He was originally from Yamashiro Province. He was a follower of Doseki NAKAMURA, and in 1630, when Doseki was dying, Doseki requested Genkaku to succeed his stipend.
Later, the stipend for the go players were succeeded as Karoku (hereditary stipend) as stipulated by the Tokugawa shogunate, and upon the death of Inseki, Dosa Inseki INOUE, the younger brother of Dosaku HONINBO, took over the Inoue house
With this, Genkaku became the first Inseki INOUE; however, during the time the Inoue house was headed by Genan Inseki INOUE, the family line was revised with Doseki becoming the first generation head of Inoue house and Genkaku becoming the second.
During the time around 1624 to 1630, there was a match between Doseki (Insekisaki) and Genkaku at the Imperial Palace and the game was a draw.
In 1644, during the investigation of the successive head of the go house after Doseki, Genkaku and Saneetsu HONINBO both declined, and neither was Santetsu YASUI able to access the post.
