Taiwan under Japanese rule in the context of "Cross-Strait relations"

The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation state that existed from the Meiji Restoration on January 3, 1868, until the Constitution of Japan took effect on May 3, 1947. From August 1910 to September 1945, it included the Japanese archipelago, the Kurils, Karafuto, Korea, and Taiwan. The South Seas Mandate and concessions such as the Kwantung Leased Territory were de jure not internal parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the formalized surrender was issued on September 2, 1945, in compliance with the Potsdam Declaration of the Allies, and the empire's territory subsequently shrunk to cover only the Japanese archipelago resembling modern Japan.

Under the slogans of "Enrich the Country, Strengthen the Armed Forces" and "Promote Industry" which followed the Boshin War and the restoration of power to the emperor from the shogun, Japan underwent a period of large-scale industrialization and militarization, often regarded as the fastest modernization of any country to date. All of these aspects contributed to Japan's emergence as a great power following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationalism, statism and authoritarianism, during which Japan joined the Axis alliance with Nazi Germany and Fascist Italy, conquering a large part of the Asia–Pacific; during this period, the Imperial Japanese Army (IJA) and the Imperial Japanese Navy (IJN) committed numerous atrocities and war crimes, including the Nanjing Massacre. There has been a debate over defining the political system of Japan as a dictatorship, which has been disputed due by the absence of a dictator, and over calling it fascist. The other suggested terms were para-fascism, militarism, corporatism, totalitarianism, and police state.

Mutsuhito (睦仁; 3 November 1852 – 29 July 1912), posthumously honored as Emperor Meiji (明治天皇, Meiji Tennō), was the 122nd emperor of Japan according to the traditional order of succession, reigning from 1867 until his death in 1912. His reign is associated with the Meiji Restoration of 1868, which ended the Tokugawa shogunate and began rapid changes that transformed Japan from an isolationist, feudal state to an industrialized world power. Emperor Meiji was the first monarch of the Empire of Japan, and presided over the Meiji era.

At the time of Mutsuhito's birth, Japan was a feudal and pre-industrial country dominated by the isolationist Tokugawa shogunate and the daimyō subject to it, who ruled over Japan's 270 decentralized domains. The opening of Japan to the West from 1854 fueled domestic demands for modernization, and when Mutsuhito became emperor after the death of his father Emperor Kōmei in 1867, it triggered the Boshin War, in which samurai (mostly from the Chōshū and Satsuma Domains) defeated the shogunate and restored power in his name. Documents issued during his reign include the Charter Oath of 1868, Meiji Constitution of 1889, Imperial Rescript to Soldiers and Sailors of 1882, and Imperial Rescript on Education of 1890, in which he was advised by a group of oligarchs known as the genrō. Other major events which occurred during his reign include the establishment of the Cabinet in 1885, Privy Council in 1888, Imperial Diet in 1890, and military victories over China in the First Sino-Japanese War and over Russia in the Russo-Japanese War. Taiwan and Korea were annexed in 1895 and 1910, respectively. Emperor Meiji died in 1912, and was succeeded by his eldest son, Yoshihito.

Taipei (/ˌtaɪˈpeɪ/ ; traditional Chinese: 臺北; simplified Chinese: 台北; pinyin: Táiběi pronounced:[tʰǎɪpèɪ]), officially Taipei City, is the capital and a special municipality of Taiwan. Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about 25 km (16 mi) southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border.

The municipality of Taipei is home to an estimated population of 2,494,813 (March 2023), forming the core part of the Taipei–Keelung metropolitan area, also known as "Greater Taipei", which includes the nearby cities of New Taipei and Keelung with a population of 7,047,559, the 40th most-populous urban area in the world—roughly one-third of Taiwanese citizens live in the metro areas. The name "Taipei" can refer either to the whole metropolitan area or just the municipality alone. Taipei has been the political center of the island since 1887, when it first became the seat of Taiwan Province by the Qing dynasty until 1895 and again from 1945 to 1956 by the Republic of China (ROC) government, with an interregnum from 1895 to 1945 as the seat of the Government-General of Taiwan during the Japanese rule. The city has been the national seat of the ROC central government since 1949, and it became the nation's first special municipality (then known as Yuan-controlled municipality) on 1 July 1967, upgrading from provincial city status.

New Taipei City is a special municipality located in northern Taiwan. The city is home to an estimated population of 4,004,367 as of January 2023, making it the most populous city in Taiwan, and also the second largest special municipality by area, behind Kaohsiung. The top-level administrative divisions bordering New Taipei City are Keelung to the northeast, Yilan County to the southeast, and Taoyuan to the southwest, and it completely encloses the capital city of Taipei. Banqiao District is its municipal seat and biggest commercial area.

Before the establishment of Spanish and Dutch outposts in Tamsui in 1626, the area of present-day New Taipei City was mostly inhabited by Taiwanese indigenous peoples, mainly the Ketagalan people. From the late Qing era, the port of Tamsui was opened up to foreign traders as one of the treaty ports after the Qing dynasty of China signed the Treaty of Tientsin in June 1858. By the 1890s, the port of Tamsui accounted for 63 percent of the overall trade for entire Taiwan, port towns in the middle course of Tamsui River had also developed into bustling business and transportation centers. During the Japanese rule of Taiwan, the entire area of New Taipei City was organized as part of the Taihoku Prefecture. After the Republic of China took control of Taiwan in 1945, the present-day New Taipei City was designated on 7 January 1946 as Taipei County in Taiwan Province, which was constituted from the former Taihoku Prefecture, but not including present-day divisions of Taipei City, Keelung and Yilan County, the latter of which became detached from Taipei County on 10 October 1950. Its county status remained until 25 December 2010 when it was promoted to special municipal status and renamed as "New Taipei City".

Keelung (/kiːˈlʊŋ/ kee-LUUNG; Chinese: 基隆; pinyin: Jīlóng; Pe̍h-ōe-jī: Ke-lâng), Chilung or Jilong (/dʒiːˈlʊŋ/ jee-LUUNG), officially known as Keelung City, is a major port city in northeastern Taiwan. The city is part of the Taipei–Keelung metropolitan area with neighboring New Taipei City and Taipei. Nicknamed the Rainy Port for its frequent rain and maritime role, the city is Taiwan's second largest seaport (after Kaohsiung), and was the world's 7th largest port in 1984.

In 1626, the Spanish established Fort San Salvador at present-day Keelung, an area inhabited by Taiwanese indigenous peoples. Control of the area eventually passed to the Qing dynasty. Fighting between China and Europeans around Keelung occurred in the 19th century during the First Opium War and the Sino-French War. The island of Taiwan was ceded to the Empire of Japan in 1895 after the First Sino-Japanese War; under Japanese rule the city was called Kirun. Keelung became part of Taiwan Province under the Republic of China after 1945. Administratively, the city became a first-level subdivision in 2018 after the provincial government was abolished.

The colonial expansion of the Empire of Japan in the Western Pacific Ocean and East Asia began in 1895 with Japan's victory over the Chinese Qing dynasty in the First Sino-Japanese War. Subsequent victories over the Russian Empire (Russo-Japanese War of 1904-1905) and the German Empire (World War I) expanded Japanese rule. Taiwan came under Japanese control from 1895, Korea in 1905, Micronesia in 1914, Southern Sakhalin in 1905, several concessions in China from 1903 onwards, and the South Manchuria Railway from 1905. In 1931, Japan invaded Manchuria, resulting in the establishment of the puppet state of Manchukuo the following year; thereafter, Japan adopted a policy of founding and supporting puppet states in conquered regions. These conquered territories became the basis for what became known as the Greater East Asia Co-Prosperity Sphere from 1940. (The Co-Prosperity Sphere expanded to include much of China, Indo-China, Malaya, the Philippines, the East Indies, Burma and New Guinea by 1942.)

Including Mainland Japan, colonies, occupied territories, and puppet states, the Empire of Japan at its apex was one of the largest empires in history. The total amount of land under Japanese sovereignty reached 8,510,000 km (3,300,000 sq mi) in 1942. By 1943, it accounted for more than 20% of the world's population at the time, with 463 million people in its occupied regions and territories.

Kana (仮名; Japanese pronunciation: [ka.na]) are syllabaries used to write Japanese phonological units, morae. In current usage, kana most commonly refers to hiragana and katakana. It can also refer to their ancestor magana (真仮名; lit. 'true kana'), which were Chinese characters used phonetically to transcribe Japanese (e.g. man'yōgana); and hentaigana, which are historical variants of the now-standard hiragana.

Katakana, with a few additions, are also used to write Ainu. A number of systems exist to write the Ryūkyūan languages, in particular Okinawan, in hiragana. Taiwanese kana were used in Taiwanese Hokkien as ruby text for Chinese characters in Taiwan when it was under Japanese rule.

The Japanese invasion of Taiwan, also known as Yiwei War in Chinese (Chinese: 乙未戰爭; May–October 1895), was a conflict between the Empire of Japan and the armed forces of the short-lived Republic of Formosa following the Qing dynasty's cession of Taiwan to Japan in April 1895 at the end of the First Sino-Japanese War. The Japanese sought to take control of their new possession, while the Republican forces fought to resist Japanese occupation. The Japanese landed near Keelung on the northern coast of Taiwan on 29 May 1895, and in a five-month campaign swept southwards to Tainan. Although their advance was slowed by guerrilla activity, the Japanese defeated the Formosan forces (a mixture of regular Chinese units and local Hakka militias) whenever they attempted to make a stand. The Japanese victory at Baguashan on 27 August, the largest battle ever fought on Taiwanese soil, doomed the Formosan resistance to an early defeat. The fall of Tainan on 21 October ended organised resistance to Japanese occupation, and inaugurated five decades of Japanese rule in Taiwan.
