Hayashi Genbi
Hayashi Genbi (1778 - 1861), also known as Genbi Monnyu, was Japanese 8-dan professional go player (his promotion was disputed). Originally a Honinbo pupil, he became the eleventh head of the Hayashi house.
Genbi was the author of three collections: Gokyo Shumyo, Gokyo Seimyo and Rankado Kiwa[1].
He has been suspected of having falsely claimed that some of Huang Longshi's games were ancient games involving Japanese players [2].
