Iino Seiho (飯野靖峯) was a Kansai Kiin professional player, born 1919-12-20, pupil of Yamaguchi 7 dan. Promoted 1 dan in 1936 and 7 dan in 1976. On the web, his name is often mistakenly read Iino Yasumine.

The Perfect Weiqi Database seems to claim that he both retired and died in 1984, but the page gives inexact dates.
(bugcat: The PWD also gives his forename as Yasumine. I am sceptical that this is any more "mistaken" than referring to Segoshi Kensaku or, of course, Fujisawa Shuko, if incorrect at all. I created Iino Yasumine as an alias of this page.)
