Hatsuta Keisuke (初田 啓介) announced 25 SASUKE tournaments. He began as the #2 announcer in SASUKE 2 and became the main announcer following Furutachi Ichiro's departure after SASUKE 12. Ogasawara Wataru moved from #2 announcer to lead after SASUKE 21 was Hatsuta's last competition until returning in SASUKE 24 and SASUKE 27 onwards to SASUKE 31. Due to being unable to announce the 2015 SASUKE, his spot as the number #1 announcer was taken over by Komada Kengo. He was the only announcer in KUNOICHI 1 and KUNOICHI 2.
Despite his two tournament absence from SASUKE, he was the lead announcer for KUNOICHI 8. He was replaced by Komada Kengo in KUNOICHI 9
