The Empire of Japan is a Nation that is the largest Empire in Asia and the Nation that is the 2nd most powerful Empire in the world behind Germany. Under the slogans of Fukoku Kyōhei and Shokusan Kōgyō, Japan underwent a period of industrialization and militarization, the Meiji Restoration being the fastest modernisation of any country to date, all of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I.

Japan after gaining it's colonial Empire is the most powerful nation when it comes to controlling trade routes in the Pacific Ocean. Japan is the third-most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the mainland's terrain is mountainous, concentrating its population of 125.57 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Area is the most populous metropolitan area in the world, with more than 37.4 million residents.

Japan has powerful companies such as Nintendo,SEGA,Sony and is the creator of the cultural art of Anime which as gained global popularity. Japan is a great power and a member of numerous international organizations, including the United Nations (since 1956), the OECD, and the Group of Seven. Although it has renounced its right to declare war, the country maintains Self-Defense Forces that are ranked as the world's fourth-most powerful military. After World War II, Japan experienced high economic growth, becoming the second-largest economy in the world. Despite stagnant growth since the Lost Decade, the country's economy remains the third-largest by nominal GDP and the fourth-largest by PPP. A leader in the automotive and electronics industries, Japan has made significant contributions to science and technology. Ranked the second-highest country on the Human Development Index in Asia after Singapore, Japan has the world's second-highest life expectancy, though it is experiencing a decline in population. The culture of Japan is well-known around the world, including its art, cuisine, music, and popular culture, which encompasses prominent animation and video game industries.


Prelude to Empire

After two centuries, the seclusion policy, or sakoku, under the shōguns of the Edo period came to an end when the country was forced open to trade by the Convention of Kanagawa which came when Matthew C. Perry arrived in Japan in 1854. Thus, the period known as Bakumatsu began.

The following years saw increased foreign trade and interaction; commercial treaties between the Tokugawa shogunate and Western countries were signed. In large part due to the humiliating terms of these unequal treaties, the shogunate soon faced internal hostility, which materialized into a radical, xenophobic movement, the sonnō jōi (literally "Revere the Emperor, expel the barbarians").

In March 1863, the Emperor issued the "order to expel barbarians." Although the shogunate had no intention of enforcing the order, it nevertheless inspired attacks against the shogunate itself and against foreigners in Japan. The Namamugi Incident during 1862 led to the murder of an Englishman, Charles Lennox Richardson, by a party of samurai from Satsuma. The British demanded reparations but were denied. While attempting to exact payment, the Royal Navy was fired on from coastal batteries near the town of Kagoshima. They responded by bombarding the port of Kagoshima in 1863. The Tokugawa government agreed to pay an indemnity for Richardson's death. Shelling of foreign shipping in Shimonoseki and attacks against foreign property led to the bombardment of Shimonoseki by a multinational force in 1864. The Chōshū clan also launched the failed coup known as the Kinmon incident. The Satsuma-Chōshū alliance was established in 1866 to combine their efforts to overthrow the Tokugawa bakufu. In early 1867, Emperor Kōmei died of smallpox and was replaced by his son, Crown Prince Mutsuhito (Meiji).

On November 9, 1867, Tokugawa Yoshinobu resigned from his post and authorities to the Emperor, agreeing to "be the instrument for carrying out" imperial orders, leading to the end of the Tokugawa shogunate. However, while Yoshinobu's resignation had created a nominal void at the highest level of government, his apparatus of state continued to exist. Moreover, the shogunal government, the Tokugawa family in particular, remained a prominent force in the evolving political order and retained many executive powers, a prospect hard-liners from Satsuma and Chōshū found intolerable.

On January 3, 1868, Satsuma-Chōshū forces seized the imperial palace in Kyoto, and the following day had the fifteen-year-old Emperor Meiji declare his own restoration to full power. Although the majority of the imperial consultative assembly was happy with the formal declaration of direct rule by the court and tended to support a continued collaboration with the Tokugawa, Saigō Takamori, leader of the Satsuma clan, threatened the assembly into abolishing the title shōgun and ordered the confiscation of Yoshinobu's lands.

On January 17, 1868, Yoshinobu declared "that he would not be bound by the proclamation of the Restoration and called on the court to rescind it". On January 24, Yoshinobu decided to prepare an attack on Kyoto, occupied by Satsuma and Chōshū forces. This decision was prompted by his learning of a series of arson attacks in Edo, starting with the burning of the outworks of Edo Castle, the main Tokugawa residence.

Boshin War

The Boshin War (戊辰戦争, Boshin Sensō) was fought between January 1868 and May 1869. The alliance of samurai from southern and western domains and court officials had now secured the cooperation of the young Emperor Meiji, who ordered the dissolution of the two-hundred-year-old Tokugawa shogunate. Tokugawa Yoshinobu launched a military campaign to seize the emperor's court at Kyoto. However, the tide rapidly turned in favor of the smaller but relatively modernized imperial faction and resulted in defections of many daimyōs to the Imperial side. The Battle of Toba–Fushimi was a decisive victory in which a combined army from Chōshū, Tosa, and Satsuma domains defeated the Tokugawa army. A series of battles were then fought in pursuit of supporters of the Shogunate; Edo surrendered to the Imperial forces and afterwards Yoshinobu personally surrendered. Yoshinobu was stripped of all his power by Emperor Meiji and most of Japan accepted the emperor's rule.

Pro-Tokugawa remnants, however, then retreated to northern Honshū (Ōuetsu Reppan Dōmei) and later to Ezo (present-day Hokkaidō), where they established the breakaway Republic of Ezo. An expeditionary force was dispatched by the new government and the Ezo Republic forces were overwhelmed. The siege of Hakodate came to an end in May 1869 and the remaining forces surrendered.

Meiji Era

The Charter Oath was made public at the enthronement of Emperor Meiji of Japan on April 7, 1868. The Oath outlined the main aims and the course of action to be followed during Emperor Meiji's reign, setting the legal stage for Japan's modernization. The Meiji leaders also aimed to boost morale and win financial support for the new government.

Japan dispatched the Iwakura Mission in 1871. The mission traveled the world in order to renegotiate the unequal treaties with the United States and European countries that Japan had been forced into during the Tokugawa shogunate, and to gather information on western social and economic systems, in order to effect the modernization of Japan. Renegotiation of the unequal treaties was universally unsuccessful, but close observation of the American and European systems inspired members on their return to bring about modernization initiatives in Japan. Japan made a territorial delimitation treaty with Russia in 1875, gaining all the Kuril islands in exchange for Sakhalin island.

The Japanese government sent observers to Western countries to observe and learn their practices, and also paid "foreign advisors" in a variety of fields to come to Japan to educate the populace. For instance, the judicial system and constitution were modeled after Prussia, described by Saburō Ienaga as "an attempt to control popular thought with a blend of Confucianism and German conservatism." The government also outlawed customs linked to Japan's feudal past, such as publicly displaying and wearing katana and the top knot, both of which were characteristic of the samurai class, which was abolished together with the caste system. This would later bring the Meiji government into conflict with the samurai.

The process of modernization was closely monitored and heavily subsidized by the Meiji government in close connection with a powerful clique of companies known as zaibatsu (e.g.: Mitsui and Mitsubishi). Borrowing and adapting technology from the West, Japan gradually took control of much of Asia's market for manufactured goods, beginning with textiles. The economic structure became very mercantilistic, importing raw materials and exporting finished products — a reflection of Japan's relative scarcity of raw materials.

Economic reforms included a unified modern currency based on the yen, banking, commercial and tax laws, stock exchanges, and a communications network. The government was initially involved in economic modernization, providing a number of "model factories" to facilitate the transition to the modern period. The transition took time. By the 1890s, however, the Meiji had successfully established a modern institutional framework that would transform Japan into an advanced capitalist economy. By this time, the government had largely relinquished direct control of the modernization process, primarily for budgetary reasons. Many of the former daimyōs, whose pensions had been paid in a lump sum, benefited greatly through investments they made in emerging industries.

Japan emerged from the Tokugawa-Meiji transition as an industrialized nation. From the onset, the Meiji rulers embraced the concept of a market economy and adopted British and North American forms of free enterprise capitalism. Rapid growth and structural change characterized Japan's two periods of economic development after 1868. Initially, the economy grew only moderately and relied heavily on traditional Japanese agriculture to finance modern industrial infrastructure. By the time the Russo-Japanese War began in 1904, 65% of employment and 38% of the gross domestic product (GDP) were still based on agriculture, but modern industry had begun to expand substantially. By the late 1920s, manufacturing and mining amounted to 34% of GDP, compared with 20% for all of agriculture. Transportation and communications developed to sustain heavy industrial development.

From 1894, Japan built an extensive empire that included Taiwan, Korea, Manchuria, and parts of northern China. The Japanese regarded this sphere of influence as a political and economic necessity, which prevented foreign states from strangling Japan by blocking its access to raw materials and crucial sea-lanes. Japan's large military force was regarded as essential to the empire's defense and prosperity by obtaining natural resources that the Japanese islands lacked.

Sino-Japanese War

The First Sino-Japanese War, fought in 1894 and 1895, revolved around the issue of control and influence over Korea under the rule of the Joseon Dynasty. Korea had traditionally been a tributary state of China's Qing Empire, which exerted large influence over the conservative Korean officials who gathered around the royal family of the Joseon kingdom. On February 27, 1876, after several confrontations between Korean isolationists and Japanese, Japan imposed the Japan–Korea Treaty of 1876, forcing Korea open to Japanese trade. The act blocks any other power from dominating Korea, resolving to end the centuries-old Chinese suzerainty.

On June 4, 1894, Korea requested aid from the Qing Empire in suppressing the Donghak Rebellion. The Qing government sent 2,800 troops to Korea. The Japanese countered by sending an 8,000-troop expeditionary force (the Oshima Composite Brigade) to Korea. The first 400 troops arrived on June 9 en route to Seoul, and 3,000 landed at Incheon on June 12. The Qing government turned down Japan's suggestion for Japan and China to cooperate to reform the Korean government. When Korea demanded that Japan withdraw its troops from Korea, the Japanese refused. In early June 1894, the 8,000 Japanese troops captured the Korean king Gojong, occupied the Royal Palace in Seoul and, by June 25, installed a puppet government in Seoul. The new pro-Japanese Korean government granted Japan the right to expel Qing forces while Japan dispatched more troops to Korea.

China objected and war ensued. Japanese ground troops routed the Chinese forces on the Liaodong Peninsula, and nearly destroyed the Chinese navy in the Battle of the Yalu River. The Treaty of Shimonoseki was signed between Japan and China, which ceded the Liaodong Peninsula and the island of Taiwan to Japan. After the peace treaty, Russia, Germany, and France forced Japan to withdraw from Liaodong Peninsula. Soon afterwards Russia occupied the Liaodong Peninsula, built the Port Arthur fortress, and based the Russian Pacific Fleet in the port. Germany occupied Jiaozhou Bay, built Tsingtao fortress and based the German East Asia Squadron in this port.

Boxer Rebellion

In 1900, Japan joined an international military coalition set up in response to the Boxer Rebellion in the Qing Empire of China. Japan provided the largest contingent of troops: 20,840, as well as 18 warships. Of the total, 20,300 were Imperial Japanese Army troops of the 5th Infantry Division under Lt. General Yamaguchi Motoomi; the remainder were 540 naval rikusentai (marines) from the Imperial Japanese Navy.[citation needed]

At the beginning of the Boxer Rebellion the Japanese only had 215 troops in northern China stationed at Tientsin; nearly all of them were naval rikusentai from the Kasagi and the Atago, under the command of Captain Shimamura Hayao. The Japanese were able to contribute 52 men to the Seymour Expedition. On June 12, 1900, the advance of the Seymour Expedition was halted some 50 kilometres (30 mi) from the capital, by mixed Boxer and Chinese regular army forces. The vastly outnumbered allies withdrew to the vicinity of Tianjin, having suffered more than 300 casualties. The army general staff in Tokyo had become aware of the worsening conditions in China and had drafted ambitious contingency plans, but in the wake of the Triple Intervention five years before, the government refused to deploy large numbers of troops unless requested by the western powers. However three days later, a provisional force of 1,300 troops commanded by Major General Fukushima Yasumasa was to be deployed to northern China. Fukushima was chosen because he spoke fluent English which enabled him to communicate with the British commander. The force landed near Tianjin on July 5.

On June 17, 1900, naval Rikusentai from the Kasagi and Atago had joined British, Russian, and German sailors to seize the Dagu forts near Tianjin. In light of the precarious situation, the British were compelled to ask Japan for additional reinforcements, as the Japanese had the only readily available forces in the region. Britain at the time was heavily engaged in the Boer War, so a large part of the British army was tied down in South Africa. Further, deploying large numbers of troops from its garrisons in India would take too much time and weaken internal security there. Overriding personal doubts, Foreign Minister Aoki Shūzō calculated that the advantages of participating in an allied coalition were too attractive to ignore. Prime Minister Yamagata agreed, but others in the cabinet demanded that there be guarantees from the British in return for the risks and costs of the major deployment of Japanese troops. On July 6, 1900, the 5th Infantry Division was alerted for possible deployment to China, but no timetable was set for this. Two days later, with more ground troops urgently needed to lift the siege of the foreign legations at Peking, the British ambassador offered the Japanese government one million British pounds in exchange for Japanese participation.

Shortly afterward, advance units of the 5th Division departed for China, bringing Japanese strength to 3,800 personnel out of the 17,000 of allied forces. The commander of the 5th Division, Lt. General Yamaguchi Motoomi, had taken operational control from Fukushima. Japanese troops were involved in the storming of Tianjin on July 14, after which the allies consolidated and awaited the remainder of the 5th Division and other coalition reinforcements. By the time the siege of legations was lifted on August 14, 1900, the Japanese force of 13,000 was the largest single contingent and made up about 40% of the approximately 33,000 strong allied expeditionary force. Japanese troops involved in the fighting had acquitted themselves well, although a British military observer felt their aggressiveness, densely-packed formations, and over-willingness to attack cost them excessive and disproportionate casualties. For example, during the Tianjin fighting, the Japanese suffered more than half of the allied casualties (400 out of 730) but comprised less than one quarter (3,800) of the force of 17,000. Similarly at Beijing, the Japanese accounted for almost two-thirds of the losses (280 of 453) even though they constituted slightly less than half of the assault force.

After the uprising, Japan and the Western countries signed the Boxer Protocol with China, which permitted them to station troops on Chinese soil to protect their citizens. After the treaty, Russia continued to occupy all of Manchuria.

Russo-Japanese War

The Russo-Japanese War was a conflict for control of Korea and parts of Manchuria between the Russian Empire and Empire of Japan that took place from 1904 to 1905. The victory greatly raised Japan's stature in the world of global politics. The war is marked by the Japanese opposition of Russian interests in Korea, Manchuria, and China, notably, the Liaodong Peninsula, controlled by the city of Ryojun.

Originally, in the Treaty of Shimonoseki, Ryojun had been given to Japan. This part of the treaty was overruled by Western powers, which gave the port to the Russian Empire, furthering Russian interests in the region. These interests came into conflict with Japanese interests. The war began with a surprise attack on the Russian Eastern fleet stationed at Port Arthur, which was followed by the Battle of Port Arthur. Those elements that attempted escape were defeated by the Japanese navy under Admiral Togo Heihachiro at the Battle of the Yellow Sea. Following a late start, the Russian Baltic fleet was denied passage through the British-controlled Suez Canal. The fleet arrived on the scene a year later, only to be annihilated in the Battle of Tsushima. While the ground war did not fare as poorly for the Russians, the Japanese forces were significantly more aggressive than their Russian counterparts and gained a political advantage that culminated with the Treaty of Portsmouth, negotiated in the United States by the American president Theodore Roosevelt. As a result, Russia lost the part of Sakhalin Island south of 50 degrees North latitude (which became Karafuto Prefecture), as well as many mineral rights in Manchuria.

Tashio Era

On 30 July 1912, Emperor Meiji died and Crown Prince Yoshihito succeeded to the throne as Emperor of Japan. In his coronation address, the newly enthroned Emperor announced his reign's nengō (era name) Taishō, meaning "great righteousness".

The end of the Meiji period was marked by huge government domestic and overseas investments and defense programs, nearly exhausted credit, and a lack of foreign reserves to pay debts. The influence of Western culture experienced in the Meiji period continued. Kobayashi Kiyochika adopted Western painting styles while continuing to work in ukiyo-e. Okakura Kakuzō kept an interest in traditional Japanese painting. Mori Ōgai studied in the West and introduced a more modern view of human life.

The events flowing from the Meiji Restoration in 1868 had seen not only the fulfillment of many domestic and foreign economic and political objectives—without Japan suffering the colonial fate of other Asian nations—but also a new intellectual ferment, in a time when there was worldwide interest in communism and socialism and an urban proletariat was developing. Universal male suffrage, social welfare, workers' rights, and nonviolent protests were ideals of the early leftist movement. Government suppression of leftist activities, however, led to more radical leftist action and even more suppression, resulting in the dissolution of the Japan Socialist Party (日本社会党 Nihon Shakaitō) only a year after its founding and general failure of the socialist movement in 1906.

The beginning of the Taishō period was marked by the Taishō political crisis in 1912–13 that interrupted the earlier politics of compromise. When Saionji Kinmochi tried to cut the military budget, the army minister resigned, bringing down the Rikken Seiyūkai cabinet. Both Yamagata Aritomo and Saionji refused to resume office, and the genrō were unable to find a solution. Public outrage over the military manipulation of the cabinet and the recall of Katsura Tarō for a third term led to still more demands for an end to genrō politics. Despite old guard opposition, the conservative forces formed a party of their own in 1913, the Rikken Dōshikai, a party that won a majority in the House over the Seiyūkai in late 1914.

On February 12, 1913, Yamamoto Gonnohyōe succeeded Katsura as prime minister. In April 1914, Ōkuma Shigenobu replaced Yamamoto.

Crown Prince Yoshihito married Sadako Kujō on 10 May 1900. Their coronation took place on November 11, 1915.

World War I

Japan entered World War I on the side of the Allies in 1914, seizing the opportunity of Germany's distraction with the European War to expand its sphere of influence in China and the Pacific. Japan declared war on Germany on August 23, 1914. Japanese and allied British Empire forces soon moved to occupy Tsingtao fortress, the German East Asia Squadron base, German-leased territories in China's Shandong Province as well as the Marianas, Caroline, and Marshall Islands in the Pacific, which were part of German New Guinea. The swift invasion in the German territory of the Kiautschou Bay concession and the Siege of Tsingtao proved successful. The German colonial troops surrendered on November 7, 1914, and Japan gained the German holdings.

After the fall of Britain and France by Germany. Germany gave it's territories with the colonies in Asia all to Japan. America gave the Philippines to Japan as a way to get Australia and New Zealand.

After WWI-Present

After Japan's victory, Japan has become a prosperous nation with hordes of resources and puppet states to control areas in Japanese territory (some included European protectorates).


Japan is a unitary state and constitutional monarchy in which the power of the Emperor is limited to a ceremonial role. Executive power is instead wielded by the Prime Minister of Japan and his Cabinet, whose sovereignty is vested in the Japanese people. Naruhito is the Emperor of Japan, having succeeded his father Akihito upon his accession to the Chrysanthemum Throne in 2019.

Japan's legislative organ is the National Diet, a bicameral parliament. It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper House of Councillors with 245 seats, whose popularly-elected members serve six-year terms. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. The prime minister as the head of government has the power to appoint and dismiss Ministers of State, and is appointed by the emperor after being designated from among the members of the Diet. Elected in the 2020 Japanese prime minister election, Yoshihide Suga is Japan's prime minister.

Historically influenced by Chinese law, the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki. Since the late 19th century, the judicial system has been largely based on the civil law of Europe, notably Germany. In 1896, Japan established a civil code based on the German Bürgerliches Gesetzbuch, which remains in effect with post–World War II modifications. The Constitution of Japan, adopted in 1947, is the oldest unamended constitution in the world. Statutory law originates in the legislature, and the constitution requires that the emperor promulgate legislation passed by the Diet without giving him the power to oppose legislation. The main body of Japanese statutory law is called the Six Codes. Japan's court system is divided into four basic tiers: the Supreme Court and three levels of lower courts.

The Empire of Japan's military is divided into two main branches: the Imperial Japanese Army and the Imperial Japanese Navy.

Imperial Japanese Army

The Imperial Japanese Army is the official ground-based armed force of the Empire of Japan from 1868 to 1945. It is controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which are nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training.

The Imperial Japanese Navy (IJN; Kyūjitai: 大日本帝國海軍 Shinjitai: 大日本帝国海軍 Dai-Nippon Teikoku Kaigun (help·info) "Navy of the Greater Japanese Empire", or 日本海軍 Nippon Kaigun, "Japanese Navy") is the navy of the Empire of Japan. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. After two centuries of stagnation during the country's ensuing seclusion policy under the shōgun of the Edo period, Japan's navy was comparatively backward when the country was forced open to trade by American intervention in 1854. This eventually led to the Meiji Restoration. Accompanying the re-ascendance of the Emperor came a period of frantic modernization and industrialization. The navy has several successes, sometimes against much more powerful enemies such as in the Sino-Japanese War and the Russo-Japanese War.
