Hashimoto Sanai

Sanai Hashimoto (橋本 左内, Hashimoto Sanai, April 19, 1834 - November 1, 1859) was a Japanese samurai and loyal supporter of the Emperor during the final days of the Tokugawa regime.

Upon returning to Echizen, he joined the Clan as a Shoinban and became Deputy Head of the Fukui Domain school.

Inviting Yokoi Shōnan as political adviser on behalf of the daimyō Matsudaira Yoshinaga, he became a key figure in the governmental reforms of the clan.

Summoned to Edo in 1857 he actively tried to promote, albeit unsuccessfully, Hitotsubashi Yoshinobu to the 14th Shogunate.

In October 2009, a descendant of Naosuke reconciled with the people of Fukui at a memorial service marking the 150th anniversary of the execution.
