Taishō era in the context of "Shōwa era"

The Meiji era (明治時代, Meiji jidai) was an era of Japanese history that extended from October 23, 1868, to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō.

The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samurai class to rebel against the Meiji government during the 1870s, most famously Saigō Takamori, who led the Satsuma Rebellion. However, there were also former samurai who remained loyal while serving in the Meiji government, such as Itō Hirobumi and Itagaki Taisuke.

Osaka (Japanese: 大阪市, Hepburn: Ōsaka-shi; pronounced [oː.sa.kaꜜ.ɕi]; commonly just 大阪, Ōsaka [oː.sa.ka] ) is a designated city in the Kansai region of Honshu in Japan. It is the capital of and most populous city in Osaka Prefecture, and the third-most populous city in Japan, following the special wards of Tokyo and Yokohama. With an estimated population of 2,816,247 as of October 1, 2025 and a population density of about 12,505 people per square kilometer, it is the largest component of the Keihanshin Metropolitan Area, which is the second-largest metropolitan area in Japan and the 10th-largest urban area in the world with more than 19 million inhabitants.

Osaka was traditionally considered Japan's economic hub. By the Kofun period (300–538) it had developed into an important regional port, and in the 7th and 8th centuries, it served briefly as the imperial capital. Osaka continued to flourish during the Edo period (1603–1867) and became known as a center of Japanese culture. Following the Meiji Restoration, Osaka greatly expanded in size and underwent rapid industrialization. The construction boom accelerated population growth throughout the following decades, and by the 1900s, Osaka was the industrial hub in the Meiji and Taishō eras. Osaka made noted contributions to redevelopment, urban planning and zoning standards in the postwar period, and the city developed rapidly as one of the major financial centers in the Keihanshin Metropolitan Area.

The Shōwa era (昭和時代, Shōwa jidai; [ɕoːwadʑidai] ) was a period of Japanese history corresponding to the reign of Emperor Shōwa (Hirohito) from December 25, 1926, until his death on January 7, 1989. It was preceded by the Taishō era and succeeded by the Heisei era.The pre-1945 and post-war Shōwa periods are almost completely different states: the pre-1945 Shōwa era (1926–1945) concerns the Empire of Japan, and the post-1945 Shōwa era (1945–1989) concerns the modern-day Japan.

Before 1945, Japan moved into political totalitarianism, ultranationalism and statism, culminating in Japan's invasion of China in 1937, part of a global period of social upheavals and conflicts such as the Great Depression and the Pacific War.

Yoshihito (嘉仁; 31 August 1879 – 25 December 1926), posthumously honored as Emperor Taishō (大正天皇, Taishō Tennō), was the 123rd emperor of Japan according to the traditional order of succession, reigning from 1912 until his death in 1926. His reign, known as the Taishō era, was characterized by a liberal and democratic shift in domestic political power, known as Taishō Democracy. Yoshihito also oversaw Japan's participation in the First World War from 1914 to 1918, the Spanish flu pandemic, and the Great Kantō earthquake of 1923.

Born to Emperor Meiji and his concubine Yanagiwara Naruko, Yoshihito was proclaimed crown prince and heir apparent in 1888, his two older siblings having died in infancy. He suffered various health problems as a child, including meningitis soon after his birth. In 1900, he married Sadako Kujō, a member of the Kujō family of the Fujiwara clan; the couple had four sons. In 1912, Yoshihito became emperor upon the death of his father, but as he suffered from neurological issues for much of his life, he played only a limited role in politics and undertook no official duties from 1919. His declining health led to appointment of his eldest son, Crown Prince Hirohito, as regent in 1921, and Hirohito succeeded him as emperor when he died in 1926.

Genrō (元老; lit. 'original elder') was an unofficial designation given to a generation of elder Japanese statesmen, all born in the 1830s and 1840s, who served as informal extraconstitutional advisors to the emperor during the Meiji, Taishō, and early Shōwa eras of Japanese history.

The institution of genrō originated with the traditional council of elders (Rōjū) common in the Edo period; however, the term genrō appears to have been coined by a newspaper only in 1892. The term is sometimes confused with the Genrōin (Chamber of Elders), a legislative body which existed from 1875–1890; however, the genrō were not related to the establishment of that body or its dissolution.

Prince Saionji Kinmochi (Japanese: 西園寺 公望; 7 December 1849 – 24 November 1940) was a Japanese statesman and diplomat who twice served as Prime Minister of Japan, in 1906–1908 and 1911–1912. He was the last surviving member of the genrō, the small group of unofficial elder statesmen who dominated Japanese politics during the Meiji and Taishō periods. As a member of the Kyoto court nobility (kuge), Saionji forged a close relationship with the imperial house from a young age and participated in the Boshin War that overthrew the Tokugawa shogunate. He spent nearly a decade studying in France, where he became a heartfelt Francophile deeply influenced by European liberalism.

Upon his return to Japan, Saionji held a series of high-ranking posts in the Meiji government, including diplomat and cabinet minister, often under the patronage of Itō Hirobumi. In 1903, he succeeded Itō as president of the Rikken Seiyūkai political party and entered into a political compromise with his rival, General Katsura Tarō. For the next decade, a period known as the Keien era, the two men alternated as prime minister, with Saionji leading cabinets from 1906 to 1908 and again from 1911 to 1912.
