The Shōgitai

The Shōgitai ( 彰義隊, roughly “Corps to Manifest Righteousness”) was a pro-Tokugawa militia formed at Edo early in 1868. It is distinct from the Seieitai — different origins, different leadership, opposite fate. It is the fighting group Sakakibara Kenkichi was invited to join during the battle of Ueno.

After defeat at Toba-Fushimi, Yoshinobu returned to Edo, and on 11 February 1868 he declared submission to the new government, and the next day entered confinement at Ueno’s Kan’ei-ji. Bakushin and Hitotsubashi-house retainers who rejected that submission organized in response; the corps was formed in 1868 to guard Yoshinobu, and it received from the bakufu the duty of policing the city of Edo.

Its head (頭取) was Shibusawa Seiichirō (渋沢成一郎, also Kisaku 喜作), a cousin of Shibusawa Eiichi, with Amano Hachirō (天野八郎, 1831–1868) as deputy; neither was a hereditary bakushin — both had risen from farming or village-headman backgrounds into Hitotsubashi or bakufu service — and the name “Shōgi” expressed the aim of making the great cause manifest, seeking Yoshinobu’s reprieve and restoration, and fighting if the new government would not grant it.

The old bakufu’s submission faction tried to manage the militia by recognizing it and giving it city-patrol duties, and it first placed its headquarters at Hongan-ji, then moved to Ueno — to Kan’ei-ji, the Tokugawa family temple, where it rallied around the Rinnōji-no-miya Kōgen Nyūdō Shinnō.

After the bloodless surrender of Edo Castle on 11 April 1868 and Yoshinobu’s removal to Mito, Shibusawa argued for withdrawing from Ueno, clashed with Amano, and left to form the Shinbugun (振武軍), eventually joining Enomoto and fighting at Hakodate, while Amano took command of the Shōgitai.

The hardliners who remained were joined by Shinsengumi remnants and stayed at Kan’ei-ji under the banner of protecting the Rinnōji-no-miya and the Tokugawa mausolea. The unit’s dress and bravado briefly made it fashionable in Edo; estimates of its strength range from over a thousand to around two thousand men.

On the Battle of Ueno ( 上野戦争 ): the Shōgitai refused the order to disband and refused to return the Rinnōji-no-miya to Kyoto, repeatedly clashing with and killing government soldiers, so that the new government’s authority in the city sank to the point that some leaders even proposed abandoning Edo Castle.

The high command then resolved to destroy it: on the 15th of the fifth month, following Ōmura Masujirō’s plan, Satsuma troops attacked frontally from the Kuromon while Chōshū struck from the Hongō Dangozaka direction and others closed in, annihilating the Shōgitai in a single day, after which the Rinnōji-no-miya escaped and later became the nominal head of the Ōuetsu Reppan Dōmei.

This was 4 July 1868, with Saigō Takamori leading the Satsuma assault at the gate, and Hizen’s Armstrong guns firing across Shinobazu Pond. Some 266 bodies were afterward gathered and cremated, which is why the Shōgitai graves stand both in Ueno Park and at Entsū-ji.

This is the same engagement, seen from the other side, in which Sakakibara — having declined the Shōgitai — got the prince out to Mikawajima. Amano was captured and died in custody that year; survivors scattered north to Aizu and the alliance or to Hakodate.
