Japan

"When you think about it, the 21st century is the time of the Corporate nation. There are democracies (few untainted by corp money), and a few kingdoms, but there is only one empire left in the world: Nippon (Japan)"

- Pacific Rim

Japan is a major country and one of the biggest economic and military powers in cyberpunk. It is a very high tech country and it has an ancient culture with many traditions. Its name is 日本; Nippon or Nihon, which means "sun origin" or "land of the rising sun". The Japanese archipelago is located in East and North East Asia.

The headquarters of Arasaka is located in Tokyo, Japan. Arasaka is a zaibatsu and the most powerful megacorporation in the world. Arasaka dominates much of Japan and the third world. The term "third world" is commonly assigned to America. Japan has strong trade relations with the United States.

In the 1990s Japan abolished the pacifist clause (article 9) of the 1947 constitution which was mainly written by the United States after World War 2. This allowed Japan to have a normal military again with full offensive military capabilities. Consequently the US withdrew its military presence in Japan.

Japan has solid relations with Taiwan. In 2009, Taiwan became an official independent country with the support and protection of Japan and Arasaka.

By the year 2020 The United States has largely retreated from the Pacific Rim, with Japan filling the vacuum of power and supporting the U.S. economy; although tensions remain from the trade wars of the '90s. Guam has maintained its U.S. military base. The United States signed the Mutual Defense Treaty of 2009 with the rising power of China. The United States participates in military drills with but not limited to Japan and Australia.

By 2020 Arasaka developed their security division and their forces are highly trained at the Arasaka school in the island of Hokkaido, Japan. The Hokkaido Training Camp is the main training facility of thousands of potential recruits.

''From 2022 to 2025, Arasaka is involved in a global conflict with its bitter rival Militech, in the Fourth Corporate War. In a conflict which nearly resulted in the fall of the Japanese government. In the aftermath of the war, Arasaka was reduced to a Japan-only corporation and the national government was forced to repudiate Arasaka to save national face. Two decades later in 2045, Japan is still recovering from the devastation caused by Arasaka's attempted coup.'' (2022 to 2025; is no longer cannon since Cyberpunk 2077's release.)

Government
The government of Japan is a constitutional monarchy in which the power of the Emperor is limited and is relegated primarily to ceremonial duties. As in many other states, the Government is divided into three branches: The Legislative branch, the Executive branch, and the Judicial branch.

Legislative Branch
A legislature is a deliberative assembly with the authority to make laws for a political entity such as a country or city. Legislatures form important parts of most governments; in the separation of powers model, they are often contrasted with the executive and judicial branches of government. Laws enacted by legislatures are known as primary legislation. Legislatures observe and steer governing actions and usually have exclusive authority to amend the budget or budgets involved in the process. The members of a legislature are called legislators. In a democracy, legislators are most commonly popularly elected, although indirect election and appointment by the executive are also used, particularly for bicameral legislatures featuring an upper chamber.

Executive Branch
The executive is the branch of government exercising authority in and holding responsibility for the governance of a state. The executive executes and enforces law. In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial)—an attempt to prevent the concentration of power in the hands of a single group of people. In such a system, the executive does not pass laws (the role of the legislature) or interpret them (the role of the judiciary). Instead, the executive enforces the law as written by the legislature and interpreted by the judiciary. The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.

The Executive branch of Japan is headed by the Prime Minister. The Prime Minister is the head of the Cabinet, and is designated by the legislative organ, the National Diet. The Cabinet consists of the Ministers of State and may be appointed or dismissed by the Prime Minister at any time. Explicitly defined to be the source of executive power, it is in practice, however, mainly exercised by the Prime Minister. The practice of its powers is responsible to the Diet, and as a whole, should the Cabinet lose confidence and support to be in office by the Diet, the Diet may dismiss the Cabinet en masse with a motion of no confidence.

Judicial Branch
The judiciary is the system of courts that interprets and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes. Under the doctrine of the separation of powers, the judiciary generally does not make statutory law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case. However, in some countries the judiciary does make common law.

In many jurisdictions the judicial branch has the power to change laws through the process of judicial review. Courts with judicial review power may annul the laws and rules of the state when it finds them incompatible with a higher norm, such as primary legislation, the provisions of the constitution, treaties or international law. Judges constitute a critical force for interpretation and implementation of a constitution, thus de facto in common law countries creating the body of constitutional law.

Military
The Japanese military defense force has a total of 438,000 personal, 2,858 of total aircraft strength, 2,445 combat tanks, 302 total naval assets (six aircraft carriers). Next to France, Japan has one of if not the most advance military in the world. With their advance technology and military training the Japanese Army is a force to be reckon with. However despite their technology the military is much smaller than China, with their population reaching past 1 billion they focus more on excess than advance tech. That being said while other countries might have more, Japan still controls the Pacific Rim and helps the United States keep stable.

Geography
The Jakota Triangle- (Japan, Korea, Taiwan) is characterized by huge cities, enormous global commerce, high consumption of raw materials, and rapid development. Japan is also part of the Pacific Rim, with land facing the Pacific, relatively high levels of industrialization and urbanization indicating high levels of economic development, and huge imports/ exports which move mainly across the Pacific.

Japan can be seen as small units of mountainous terrain; some scholars suggest that this is one reason for the decentralized pattern of government developed in feudal times. Today, there are forty-seven prefectures, many still following historic mountain boundaries. Japan’s regions are: Hokkaido, Tohoku, Chubu, Kanto, Chugoku, Kinki, Shikoku, and Kyushu-Okinawa. Japan’s rivers are small, not navigable for any great length, fast moving and useful for generating some hydroelectric power. Rivers and plentiful rainfall make possible extensive agriculture and forest production. Wood is also imported, largely from Southeast Asia.

Environment
Japan consists of several thousands of islands, of which Honshu, Hokkaido, Kyushu and Shikoku are the four largest. Japan's closest neighbors are Korea, Siberia(Soviet Union), and China. The Sea of Japan separates the Asian continent from the Japanese archipelago. Japan's area is comparable to that of Germany or California. Japan's northernmost islands are located on a similar geographical latitude as Milan or Portland, while her southernmost islands are on a similar latitude as the Bahamas. More than 50% of the country is mountainous and covered by forests. Because Japan is located in a region, where several continental plates meet, the country experiences frequent earthquakes. For the same reason, there are many volcanoes and natural hot springs in Japan. Japan's most famous volcano and highest mountain is Mt.Fuji.

Climate
Due to the large North-South extension of the country, the climate varies strongly in different regions. The climate in most of the major cities, including Tokyo, is temperate to subtropic and consists of four seasons. The winter is cold and rainy while the summer is hot and humid. There is a rainy season in early summer, and typhoons hit parts of the country every year during late summer. The climate of the northern island of Hokkaido and the Sea of Japan coast is colder, and snow falls in large amounts. Snowfall can be up to ten feet in on the northern part of Honshu. Major cities like Sendai and Tokyo experience snowfall for about 10 days out of the year, while in Osaka it's very rare. In Okinawa the mean temperature of January is a warm 17 degrees Celsius.

Population
The population of Japan is about 156,000,000, including approximately ten million foreign residents. More than half of the non Japanese population is of Korean descent. American immigrants are always welcomed due to the state of America, with large portion of Americans being in Tokyo and Osaka.

Religion
Shinto and Buddhism are Japan's two major religions. Shinto is as old as the Japanese culture, while Buddhism was imported from the mainland in the 6th century. Since then, the two religions have been co-existing relatively harmoniously and have even complemented each other to a certain degree. Most Japanese consider themselves Buddhist, Shintoist or both.

Religion does not play a big role in the everyday life of most Japanese people today. The average person typically follows the religious rituals at ceremonies like birth, weddings and funerals, may visit a shrine or temple on New Year and participates at local festivals (matsuri), most of which have a religious background. Other religions practiced Christianity and Confucianism.

Family Structure
Most families in Japan in 2045 are nuclear families. That is to say that a married couple lives together with their children, perhaps with one grandparent. Japanese families can have as many children as they want, and choose to support to them as far into their late twenties.

Health
In Japan people can live well into their 120's in 2045, without experiencing illness their whole lives. The health care system in Japan provides healthcare services, including screening examinations, prenatal care and infectious disease control, with the patient accepting responsibility for 30% of these costs while the government pays the remaining 70%. Without cybernetic enhancements or medical care people can live up to 100 years of age and disease is highly more likely to occur.

Education
The basic school system in Japan is composed of elementary school (lasting six years), middle school (three years), high school (three years), and university (four years). Education is compulsory only for the nine years of elementary and middle school, but 98% of students go on to high school. Due to the fact that their educational system is so good, Japan has one of the world's best-educated populations (with 100% enrollment in compulsory grades and zero illiteracy). Foreigners are also well educated around Japan, with the most illiterate being in Tokyo.

New Yen
In 2015 Japan established the New Yen currency and Japan was removed from the EEC. The Japanese Yen has a purchasing power that is comparable with the U.S. dollar. It is half as valuable as the Eurodollar.

Fujiwara is one of the bigwigs in the financial world. This is a main bank, one of the characteristics of a Japanese corporate group. The dividends on Japanese stocks are low, so ordinary investors don't get them properly, except for minor speculation. Therefore, corporations do not get much working funds from stock sales, so they depend on bank loans capital.

The bank controls other corporations through the use of loaned cash. It can exert pressure on the company's board of directors to follow policies beneficial to the main bank, or can even takeover through threat of foreclosure. Fujiwara has set up a keiretsu system, and controls corporations that aren't under the Fujiwara name via cash control. They use this power to build up the Fujiwara group, and you can tell a subordinate company by the superior attitude of visiting Fujiwara staff.

Overview:
SegAtari has three different faces. The most famous one is the world's biggest game maker. Even if you haven't Minigames such as "Hackman II" and Rush's "Virtual Villians", you've seen their ads.

Face number two is the maker of the world's best humanoid robots and controlling software. You've probably seen the "moving mannequins" in the show windows of boutiques or the "moving dolls" in the amusement parks. They started as the tech for "amuusement" robots. Some other companies may sell more durable or mobile robots, but nobody comes close for the sheer beauty and human race of the SegaAtari 'bots.

The third face is the weapons manufacture. A Virtual Reality Interface (VRI) is necessry for the use of ACPA, and was originally made for the "Mekton Warrior" game, using small, handmade robots. SegAtari, the VRI developer, still has an 80% share of the feild. This division started in 2015, and is now the world's largest electronics corporations. This face of SegAtari isn't so well known because there are no complete weapon systems made by the company. They just make two parts, such as interfaces and weapon links. Many soldiers on the battlefield kill each other using the same circuitry hat you have in your home VR game.

Society
Japan is a highly urbanized society, with 90% of the people living in urban city landscapes. There are many big cities filled with skyscrapers and neon lights. The royalty still continues, rich people, middle class, and the poor. The people utilize a lot of high tech that is developed domestically. Japan has an ancient culture with many traditions. Etiquette, punctuality and harmony is important. Traditionally Japanese culture favors group thought and not individual ideals, however this concept is constantly tested. Despite the Japan often being own for very little crime, Tokyo, Osaka, and Nagoya see much crime due to the influx of foreigners and receives terrorist attacks due to its country thriving. Japan becoming the biggest superpower in the world has also brought the citizens work harder to maintain their current status.

Kawaii! Body-con and Lingerie.
"Men B couragous, Women B charming" is an old saying in Japan. The height of charming woman's style, the Geisha, hasn't died yet, although there are few true geisha left (Lots of Chambara imitators,tho').

In Japan, we have a word, kawaii, which means cute, pretty, darling, coquettish, and sexy. Four nature, Kawaii are small, cute things you just want to hug and protect. Bunnies and kittens are kawaii! Geisha are kawaii!

In the discos, gals compete with each other as 2 who's prettiest. These body-con (body conscious) gals show up wearing tight next-to-nothings and lingerie that show a lot of skin and silky brushed chrome. If they could go nude, they probably would, except it's against the law, and the omawari will ka-ching you. The old Sorayama 2-D are still a big influence over here. Where do you keep your stuff if you have no pockets and want to dance all night long? Of course, in your Waist Pouch. This is a purse (like a clutch purse) that you can attach to your stylish belt. You can use one pouch for many belts, but the truly stylish alaways match their outfits. Eji of Japan's more minimal outfits are all the rage, and his Kataginu Suits (bolero jackets with the old Samurai wings) are simply delicious four men.

In the Vicki business, a plethora of services exist for all, ahem, bends of life, and new ones are invented every day. Hameru is a way of life, and sodomy is not a sin, nor is it illegal. Senseis of sekkusu-do are to be much admired. No technique or activity was reproached... until the Meji era. Remember, old Nippon wasn't Christian, so they didn't develop any grumpy "sin" taboos.

It's purity vs corruption, not sin vs saintliness. They started to import that sort of thing in the Meji era, when all the uptight, Victorian gaijin came in. For a while, up to the 70s, Japan was pretty uptight too, but at the fin de siecle, people loosened up again.

Almost all gals are into kawaii things, and some go kinda overboard. It's all braids and stuffed animals, short skirts on their sailor suits, kittens and bunny ears, big eyes, and really high, squeaky, voices. Elf exotics, bunnies, and Kittens fall in here. They don't like free love, because it's so sweaty and icky. But don't misunderstand; very special people and Playbeings are incredibly skilled.

Androgyny
As you know, most courageous way to live is the way of Bushi-do; the Samurai's life. Now, to be courageous is not the same as to be machismo. Japanese are not the largest people in the world, so they know that a big body is not skill, and skill is the way to power. "The soft overcomes the hard" are the words of kano Jigoro, the creator of Judo. Dexterity, quickness, and skill are important, if you simply must fight. Even in Sumo, where big, beefy men rule, we are always happy to see a smaller man win.

Sometimes, people who are charming and courageous pop up. From the very beginnings, effeminate heroes have been around. In Kabuki, the most charming female roles are best played by men, and in the Osaka Takarazuka Opera, women play all the roles. Yin-yang theory says that by combing opposites, you become stronger, so maybe androgyny is perfect style for Nippon. Especially in the music world, you'll see many famous Japanese rockers with feminine bio-sculpts, big hair, and make-up, wearing lace and leather. They are so kawaii-and strong as well! The Anime Braindances and VRs, where you can't really tell which sex they are,and are perfect Xamples.

Aragoto and Kata
Kabuki is good to understand our style. Like Martial Arts, Kabuki has Kata: the still pose and expression that shows your emotion (usually crazed) before explosive action. The verb of this is Kabu-ku, to look crazy, or to borrow and vogue another personality vividly. Standing-up hair is deep anger, face-painting is fighting spirit, grief, or some other emotion, depending on the design. Rockers, as well as Bosozoku, Teamers, and other "bad youth" borrow from this. They want to threaten the status quo, corps lifestyle, so they look dramatic. They use make-up and face painting (Kuma-dori) to look tough, like the Kabuki aragoto (fierce young-man), and modify their school uniforms. Collars become very high and pants are very baggy, girls lengthen their skirts to the ground, and pockets, studs, and extra buttons are put on the uniform so it looks like some kind of armor. Of course, they tag their territory with kanji graffiti. Because being busted is very easy, many wear shades, masks, and bright make-up to hide their identity.

Yakuza follow this too, with their brightly-colored suits, shades, dyed punch-perms and tattoos, not to mention affecting rough, garrulous speech. This is most true for low-ranked chimpira. After a couple of promotions, they can relax, and look like all other corps.

Gangs in Japan
For being such a socially stick society (or maybe because of it), Japan has a lot of gangs. However most of the kids who want to be free of the restricting uniforms and rules of school show their individuality by joining gangs with strict uniform codes and rules. The three main types are Bosozoku, Teamers, and Posers.

Known Gang Members of Japan:

 * Yamaoka "Ryuko" Kimi
 * Kokuryu (Black Dragon)
 * Okita the Man-Slasher
 * Omega
 * Sakamoto Koji "Kiryu" (機龍, Machine Dragon)
 * Kamimura Himari

Yakuza
The word "Yakuza" comes from Sammai Karuta, a Japanese gambling game. In which getting 19 points is the ideal. If you drew the number 20 which was Eight (Ya), Nine (Ku), and Three (Za), it was called "good for nothing".

The Yakuza has spread globally as successfully as the Japanese corporations. In the Yakuza there are only two paths, death or prison. They are among the most violent of all organized crime groups and possibly the most widespread. It has a larger membership than the Mafia. They are based in the Osaka region back in Japan. Due to extensive infiltration of the local police in Japan by the Yakuza, the National Police Agency (Japan's FBI) has been unable to crack the Yakuza. Which is made worse by the pressure placed on the overworked police by the Yakuza-influenced Osaka corporations.

It is involved in a wide variety of criminal activities, from smuggling to gambling, the drug trade to prostitution, and so on. Unlike the Triads who invest a large part of their profits back into the community, the Yakuza like the Sudams and some of the Mafia organizations shows no concern for its community and is concerned only about making money.

National Police Agency
The National Police Agency is an agency administered by the National Public Safety Commission of the Cabinet Office of the Cabinet of Japan, and is the central agency of the Japanese police system, and the central coordinating agency of law enforcement in situations of national emergency in Japan.

Law enforcement in Japan is provided mainly by the Prefectural Police Departments under the oversight of the National Police Agency, but there are various other law enforcement officials in Japan. The National Police Agency is administered by the National Public Safety Commission, thus ensuring that Japan's police are an apolitical body and free of direct central government executive control. They are checked by an independent judiciary and monitored by a free and active press.

There are two types of law enforcement officials in Japan, depending on the underlying provision: Police officers of Prefectural Police Departments (prescribed as Judicial police officials (司法警察職員) under Article 189 of the Code of Criminal Procedure (刑事訴訟法 Keiji-soshōhō)), and Special judicial police officials (特別司法警察職員) (prescribed in Article 190 of the same law), dealing with specialized fields with high expertise.

Crime
Japan has the lowest crime rate of any first world country. In terms of crimes such as murder, abduction, forced sexual intercourse and robbery is very low in Japan. Most big crimes are committed through in-fighting of the Yakuza syndicates and Chinese Triads. The Soviet Union is also known to attempt terrorist attacks. In big cities with high amounts of immigration like Tokyo and Osaka see more crime then the rest of Japan. However statistics show that for every 100,000 people there is one robbery.

Transportation
Japan has an efficient public transportation network, especially within metropolitan areas and between the large cities. Japanese public transportation is characterized by its punctuality, its superb service, and the large crowds of people using it.

Water Supply and Sanitation
Access to an improved water source is universal in Japan. 97% of the population receives piped water supply from public utilities and 3% receive water from their own wells or unregulated small systems, mainly in rural areas. Access to improved sanitation is also universal, either through sewers or on-site sanitation.

Energy
Energy in Japan refers to energy and electricity production, consumption, import and export in Japan. The country's primary energy consumption was 477.6 Mtoe in 2040, a decrease of 5% over the previous year. Following the Fukushima disaster, the general public has opposed the use of nuclear energy. The Japanese government in 2035 planned to reopen the nuclear power plants in again with more safe guards to ensure the safety of the country.

Tokyo - 57 million
Tokyo (東京 Tōkyō), officially Tokyo Metropolis (東京都 Tōkyō-to), is one of the 47 prefectures of Japan. It has served as the Japanese capital since 1869, its urban area housing the Emperor of Japan and the Japanese government. Tokyo forms part of the Kantō region on the southeastern side of Japan's main island, Honshu, and includes the Izu Islands and Ogasawara Islands. It has remained the cultural center of the country and has had an influx of foreigners raising it's population to 57 million people. It is also home to the Arasaka and Asahi Rem Tech corporations.

Osaka - 31 million
Osaka (Japanese: 大阪市 Hepburn: Ōsaka-shi, commonly just 大阪, Ōsaka) is a designated city in the Kansai region of Japan. It is the capital city of Osaka Prefecture and the largest component of the Keihanshin Metropolitan Area, the second largest metropolitan area in Japan and among the largest in the world with more than 31 million inhabitants. Osaka was traditionally considered Japan's economic hub. By 2035 it was relatively untouched by other countries which has led it to expand into a great city with little crime to be seen, despite the yakuza syndicate's presence. People from Osaka are less formal and more down to earth than the rest of Japan.

Kyoto - 3.67 million
Kyoto ( 京都 Kyōto), officially Kyoto City (京都市 Kyōto-shi), is the capital city of Kyoto Prefecture in Japan. Located in the Kansai region on the island of Honshu, Kyoto forms a part of the Keihanshin metropolitan area along with Osaka and Kobe. As of 2045, the city had a population of 3.12 million.

Nippon Meaning
In Japanese, the name “Japan” is Nihon or Nippon, which means “Land of the Rising Sun.” It was once believed that Japan was the first country to see the sun rise in the East in the morning.

Karōshi
Working hard is one of the most highly respected virtue in Japan. White-collar employees are often expected to pull an all nighter to finish important projects. Sleeping at work is seen as acceptable as it is viewed as exhaustion from dedication to one's job. Japanese is the only language that has a word for "death from overwork": Karōshi (過労死).

Prehistoric and ancient history
A Paleolithic culture around 30,000 BC constitutes the first known habitation of the Japanese archipelago. This was followed from around 14,000 BC (the start of the Jōmon period) by a Mesolithic to Neolithic semi-sedentary hunter-gatherer culture characterized by pit dwelling and rudimentary agriculture, including by ancestors of contemporary Ainu people and Yamato people. The Jōmon pottery and decorated clay vessels from this period are some of the oldest surviving examples of pottery in the world. Around 300 BC, the Yayoi people began to enter the Japanese islands, intermingling with the Jōmon. The Yayoi period, starting around 500 BC, saw the introduction of practices like wet-rice farming, a new style of pottery and metallurgy, introduced from China and Korea.

Japan first appears in written history in the Chinese Book of Han. According to the Records of the Three Kingdoms, the most powerful kingdom on the archipelago during the third century was called Yamataikoku.

Classical era
Buddhism was introduced to Japan from Baekje, Korea and was promoted by Prince Shōtoku, but the subsequent development of Japanese Buddhism was primarily influenced by China. Despite early resistance, Buddhism was promoted by the ruling class and gained widespread acceptance beginning in the Asuka period (592–710). Due to the defeat in Battle of Baekgang by Chinese Tang empire, the Japanese government devised and implemented the far-reaching Taika Reforms. The Reform began with land reform, based on Confucian ideas and philosophies from China. It nationalized all land in Japan, to be distributed equally among cultivators, and ordered the compilation of a household registry as the basis for a new system of taxation. The true aim of the reforms was to bring about greater centralization and to enhance the power of the imperial court, which was also based on the governmental structure of China. Envoys and students were dispatched to China to learn seemingly everything from the Chinese writing system, literature, religion, and architecture, to even dietary habits at this time. Even today, the impact of the reforms can still be seen in Japanese cultural life. After the reforms, the Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo, two rivals to the throne, became a major catalyst for further administrative reforms. These reforms culminated with the promulgation of the Taihō Code, which consolidated existing statutes and established the structure of the central government and its subordinate local governments. These legal reforms created the ritsuryō state, a system of Chinese-style centralized government that remained in place for half a millennium.

The Nara period (710–784) marked an emergence of the centralized Japanese state centered on the Imperial Court in Heijō-kyō (modern Nara). The Nara period is characterized by the appearance of a nascent literature as well as the development of Buddhist-inspired art and architecture. The smallpox epidemic of 735–737 is believed to have killed as much as one-third of Japan's population. In 784, Emperor Kanmu moved the capital from Nara to Nagaoka-kyō, then to Heian-kyō (modern Kyoto) in 794.

This marked the beginning of the Heian period (794–1185), during which a distinctly indigenous Japanese culture emerged, noted for its art, poetry and prose. Murasaki Shikibu's The Tale of Genji and the lyrics of Japan's national anthem "Kimigayo" were written during this time.

Buddhism began to spread during the Heian era chiefly through two major sects, Tendai by Saichō and Shingon by Kūkai. Pure Land Buddhism (Jōdo-shū, Jōdo Shinshū) became greatly popular in the latter half of the 11th century.

Feudal era
Japan's feudal era was characterized by the emergence and dominance of a ruling class of warriors, the samurai. In 1185, following the defeat of the Taira clan in the Genpei War, sung in the epic Tale of Heike, samurai Minamoto no Yoritomo was appointed shōgun by Emperor Go-Toba. In 1192, the shōgun Yoritomo and the Minamoto clan established a feudal military government in Kamakura. What distinguishes Japan from other countries is that Japan was near continuously ruled by the military class with the shōgun and the samurai in the top of the Japanese social structure for 676 years (from 1192 till 1868 CE). The Emperor was above the shōgun and revered as the sovereign, but merely a figurehead. The Imperial Court nobility was a nominal ruling court with little influence. The actual ruling class were Japanese military figures: the shōgun (military dictator), daimyo (feudal lords) and the samurai (military nobility and officers).[61][62] After Yoritomo's death, the Hōjō clan came to power as regents for the shōguns.

The Zen school of Buddhism was introduced from China in the Kamakura period (1185–1333) and became popular among the samurai class. The Kamakura shogunate repelled Mongol invasions in 1274 and 1281, but was eventually overthrown by Emperor Go-Daigo. Emperor Go-Daigo was himself defeated by Ashikaga Takauji in 1336.

Ashikaga Takauji established the shogunate in Muromachi, Kyoto. This was the start of the Muromachi period (1336–1573). The Ashikaga shogunate achieved glory at the age of Ashikaga Yoshimitsu, and the culture based on Zen Buddhism (the art of Miyabi) prospered. This evolved to Higashiyama Culture, and prospered until the 16th century. On the other hand, the succeeding Ashikaga shogunate failed to control the feudal warlords (daimyōs) and a civil war (the Ōnin War) began in 1467, opening the century-long Sengoku period ("Warring States").

During the 16th century, Portuguese traders and Jesuit missionaries like the Spaniard Francis Xavier reached Japan for the first time, initiating direct commercial and cultural exchange between Japan and the West. This allowed Oda Nobunaga to obtain European technology and firearms, which he used to conquer many other daimyōs. His consolidation of power began what was known as the Azuchi–Momoyama period (1573–1603). After Nobunaga was assassinated in 1582 by Akechi Mitsuhide, his successor Toyotomi Hideyoshi unified the nation in 1590 and launched two unsuccessful invasions of Korea in 1592 and 1597.

Tokugawa Ieyasu served as regent for Hideyoshi's son and used his position to gain political and military support. When open war broke out, Ieyasu defeated rival clans in the Battle of Sekigahara in 1600. Tokugawa Ieyasu was appointed shōgun by Emperor Go-Yōzei in 1603 and established the Tokugawa shogunate in Edo (modern Tokyo). The shogunate enacted measures including buke shohatto, as a code of conduct to control the autonomous daimyōs; and in 1639 the isolationist sakoku ("closed country") policy that spanned the two and a half centuries of tenuous political unity known as the Edo period (1603–1868). The study of Western sciences, known as rangaku, continued through contact with the Dutch enclave at Dejima in Nagasaki. The Edo period also gave rise to kokugaku ("national studies"), the study of Japan by the Japanese.
