A report on Imperial Japanese Army and Chōshū Domain

In 1947, with American involvement, a new constitution was enacted, officially bringing the Empire of Japan to an end, and Japan's Imperial Army was replaced with the Japan Self-Defense Forces.

The nomenclature Empire of Japan had existed since the anti-Tokugawa domains, Satsuma and Chōshū, which founded their new government during the Meiji Restoration, with the intention of forming a modern state to resist Western domination.

As the Imperial Japanese Army's inaugural Chief of Staff, he was the chief architect of the Empire of Japan's military and its reactionary ideology.

He had his coming of age ceremony (genpuku) at age 15, and started off as a petty official at the Chōshū Domain and then at the Meirinkan.

The foundation of the Meiji Restoration was the 1866 Satsuma-Chōshū Alliance between Saigō Takamori and Kido Takayoshi, leaders of the reformist elements in the Satsuma and Chōshū Domains at the southwestern end of the Japanese archipelago.

This rebellion was, however, put down swiftly by the newly formed Imperial Japanese Army, trained in Western tactics and weapons, even though the core of the new army was the Tokyo police force, which was largely composed of former samurai.

The Government of Meiji Japan (明治政府) was the government that was formed by politicians of the Satsuma Domain and Chōshū Domain in the 1860s.

To further strengthen the authority of the state, the Supreme War Council was established under the leadership of Yamagata Aritomo a Chōshū native who has been credited with the founding of the modern Imperial Japanese Army and was to become the first constitutional Prime Minister.

He was a Gensui (or Marshal) in the Imperial Japanese Army and the Prime Minister of Japan from 1916 to 1918.

Terauchi Masatake was born in Hirai Village, Suo Province (present-day Yamaguchi city, Yamaguchi Prefecture), and was the third son of Utada Masasuke, a samurai in the service of Chōshū Domain.

The domains of Chōshū, Hizen, Tosa and Kaga joined Satsuma in acquiring ships.

In 1874, the Taiwan expedition was the first foray abroad of the new Imperial Japanese Navy and Army after the Mudan Incident of 1871, however the navy served largely as a transport force.

The Kiheitai (奇兵隊) was a volunteer militia raised by Takasugi Shinsaku of the Chōshū domain during the Bakumatsu period of Japan.

The success of the socially mixed unit and its Western armaments and tactics was an important influence on the development of the Imperial Japanese Army, and on the later system of universal military conscription in Japan.

He was the "Father" of the Imperial Japanese Army, launching a modern military force closely patterned after the French system of the day.

Ōmura was born in what is now part of Yamaguchi city, in the former Chōshū Domain, where his father was a rural physician.

Viscount Ōshima Yoshimasa (大島 義昌) was a general in the early Imperial Japanese Army during the First Sino-Japanese War and the Russo-Japanese War.

Ōshima was born as the eldest son to a samurai of Chōshū Domain (present-day Yamaguchi Prefecture), and fought as a member of the Satchō Alliance forces in support of Emperor Meiji during the Boshin War against the Tokugawa shogunate.
