Ии Наосукэ
Ii Naosuke regarded the Harris treaty, which Hotta Masayoshi had negotiated with the American envoy Townsend Harris as in Japan's best interests. In accordance with the protocol he asked the three house lords of the "gosankyō" for their views in writing. However Ii faced a problem in the form of an obstructionist policy from members of the Hitotsubashi faction led by Hitotsubashi Keiki's father Tokugawa Nariaki.
