Han (Japan) in the context of "Aizu domain"

The Tosa Domain (土佐藩, Tosa-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, controlling all of Tosa Province in what is now Kōchi Prefecture on the island of Shikoku. It was centered around Kōchi Castle, and was ruled throughout its history by the tozama daimyō Yamauchi clan. Many people from the domain played important roles in events of the late Edo period including Nakahama Manjirō, Sakamoto Ryōma, Yui Mitsue, Gotō Shōjirō, Itagaki Taisuke, Nakae Chōmin, and Takechi Hanpeita. Tosa Domain was renamed Kōchi Domain (高知藩, Kōchi-han) during the early Meiji period until it was dissolved in the abolition of the han system in 1871 and became Kōchi Prefecture.

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.

Shimabara Domain (島原藩, Shimabara-han) was a Japanese domain of the Edo period. Originally known as Hinoe Domain, its administrative center was initially established at Hinoe Castle in Minamishimabara, Nagasaki Prefecture. However, it was later relocated to Shimabara Castle in Shimabara, Nagasaki Prefecture. The domain was governed by various fudai daimyō clans, including the Koriki clan and the Fukōzu-Matsudaira clan.

The Ikedaya incident (池田屋事件, Ikedaya jiken), also known as the Ikedaya affair or Ikedaya riot, was an armed encounter between the shishi which included masterless samurai (rōnin) formally employed by the Chōshū, Tosa and Higo domains (han), and the Shinsengumi, the Bakufu's special police force in Kyoto on July 8, 1864, at the Ikedaya Inn in Sanjō-Kawaramachi, Kyoto, Japan.

Chōfu Domain (長府藩, Chōfu-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, in what is now part of Shimonoseki, Yamaguchi Prefecture. It was centered around Kushizaki Castle and was ruled throughout its history by a cadet branch of the Mōri clan. Chōfu Domain was dissolved in the abolition of the han system in 1871. The domain was also called Nagato-Chōfu Domain (長門長府藩, Nagato-Chōfu-han) or Nagato-Fuchū Domain (長門府中藩, Nagato-Fuchū-han).

The Kaga Domain (加賀藩, Kaga-han), also known as the Kanazawa Domain (金沢藩, Kanazawa-han), was a domain of the Tokugawa Shogunate of Japan during the Edo period from 1583 to 1871.

The Kaga Domain was based at Kanazawa Castle in Kaga Province, in the modern city of Kanazawa, located in the Chūbu region of the island of Honshu. The Kaga Domain was ruled for its existence by the tozama daimyō of the Maeda, and covered most of Kaga Province and Etchū Province and all of Noto Province in the Hokuriku region. The Kaga Domain had an assessed kokudaka of over one million koku, making it by far the largest domain of the Tokugawa shogunate. The Kaga Domain was dissolved in the abolition of the han system in 1871 by the Meiji government and its territory was absorbed into Ishikawa Prefecture and Toyama Prefecture.

Okutono Domain (奥殿藩, Okutono-han), also known as Okudono, was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Kamo District and Nukata Districts of Mikawa Province (part of modern Aichi Prefecture), and in Saku District, Shinano Province, (part of modern Nagano Prefecture) Japan. The domain was also known as Ogyū Domain (大給藩, Ogyū-han) and later known as Tanoguchi Domain (田野口藩, Tanoguchi-han) and Tatsuoka Domain (龍岡藩, Tatsuoka-han). The ruling family was the Ogyū-Matsudaira clan.
