Satō Fumiyasu (佐藤 文康) started as SASUKE 22's #2 announcer. Because he sounds nearly identical to former announcer Hatsuta Keisuke, some thought that Hatsuta had not left.
Hatsuta returned in SASUKE 24, moving Satō down to #3 announcer; this was the first competition which had three announcers (second was SASUKE 27). Because of this, he is also the first of three announcers to sit in the third announcer chair (the others being Kumazaki Kazato and Nanba Masatoshi).
Hatsuta left after that tournament while Ogasawara was unable to attend and Satō became the #1 announcer in SASUKE 25. Former SASUKE competitor Itō Ryūsuke moved into Satō's old position as the #2 announcer. In SASUKE 26 Ogasawara was able to return and Satō returned to his old posistion as the #2 announcer. Hatsuta again returned in SASUKE 27, moving Satō down to #3 announcer once again.
He returned in SASUKE 36 as the #1 announcer, replacing Komada Kengo. However, in SASUKE 37, he was left once again and was replaced by Sugiyama Shinya.
