Matsudaira Sadanobu
He was outranged by the treatment of "Dainagon" Nakayama Naruchika by the shogunate over an issue pertaining to the regnal name for Emperor Kōkaku and publicly criticized the "rōjū" Matsudaira Sadanobu. Forced to leave Kyoto, he travelled to Kyushu in hopes of enlisting Satsuma Domain in his efforts against the shogunate, but was rebuffed. After traveling to various parts of Kyushu, he was arrested by the shogunate at the home of a friend in Kurume, Fukuoka and was invited to commit "seppuku".
