Ogasawara Wataru (小笠原 亘) became SASUKE's main announcer when Hatsuta Keisuke left after SASUKE 21. He replaced Komada Kengo as the #2 announcer for SASUKE 14. Ogasawara became the main announcer when Hatsuta Keisuke was absent from SASUKE 22 and SASUKE 23. He moved to announcer number #2 when Hatsuta Keisuke returned in SASUKE 24. Ogasawara was unable to announce SASUKE 25 for unknown reasons, most likely due to a schedule conflict. Ogasawara returned to announce SASUKE 26 and SASUKE 27, the latter which would be his last tournament as an announcer for SASUKE before an eight-year hiatus. He was replaced by Ishii Tomohiro in the following tournament. He returned in SASUKE 37 as the #2 announcer after Sugiyama Shinya moved to the #1 spot.
Of the many, many translation errors that G4 has made while dubbing Ninja Warrior, arguably the most egregious involves Ogasawara. In SASUKE 23, G4 gave Ogasawara's name for competitor #51 -- Kinoshita Takayuki. Ogasawara had just replaced Satō Fumiyasu as announcer, who called the first half of the First Stage.
