- Other Names: 忠敝 (Chûhei), 忠太夫 (Chûdayû)
- Japanese: 戸田 銀次郎 (Toda Ginjirou)
Ginjirô was placed under house arrest by the shogunate along with former lord of Mito Tokugawa Nariaki and fellow karô Fujita Toranosuke; Toda and Fujita were released, however, on 1846/12/28, while Nariaki remained confined for a time.
By 1853, Toda and Fujita were actively engaged in petitioning the shogunate to allow for Nariaki's involvement in discussions or policy decisions regarding foreign relations and coastal defense; they were eventually successful, and Nariaki was formally brought into policy discussions.
