Honinbo Jowa (本因坊丈和, original name Todani Matsunosuke, 1787–1847) served as 12th Hon'inbō from 1827 and Meijin Godokoro from 1831 until 1839, when he was forced into retirement.
At some point in the Meiji Era this title was transferred to the more popular Shūsaku, as word was spread that Jōwa used the contacts that Hayashi Genbi had within the government to help him attain the Meijin Godokoro position.
[1] The match started with Jōwa making an unreasonably aggressive move in the fuseki, and Akaboshi countering with a variation of the taisha joseki that was developed secretly in the Inoue house.
The three moves were supposedly brought to Jōwa by ghosts, allowing him to grind Intetsu's lead away.
Gennan's tactics for discrediting Jowa's worthiness of being appointed Meijin backfired spectacularly, as this game was the supreme triumph of Jōwa's career.
