On 1854/3/27, Kaneko and Yoshida snuck aboard Commodore Perry's flagship, anchored at Shimoda, and asked that Perry take them overseas. He refused, and the pair turned themselves in to Tokugawa shogunate authorities the next day. The pair were imprisoned at Tenma-chô in Edo for a time, before being sent to Chôshû to be kept under house arrest.
