Tsutsui Katsumi (筒井勝美, 1930--20??) was a Nihon Ki-in professional.
It's very likely that he received his final promotion on retirement. 
He is deceased.  It's unclear when he died, and the AGA has not published an obituary. This information may be available in Japanese on the Nihon Ki-in site.
His kifu are not available on either Waltheri or Go4Go.
 Judging by the Nihon Ki-in site, which shows his last games as in 2004.
