After Dosaku died in 1702, Dōchi was passed on to Inoue Dōsetsu Inseki.
He played in an international match against a visiting Ryukyuan player, the Satonushi of Yara.

Yasui Senkaku had originally refused to play the relatively untested Dōchi; the match had been set up by Ohashi Sokei, the shogidokoro, who was a conventional go-between, and the celebrated game occurred in his official residence.
