Since taking over the high school program, in just 10 seasons (2 canceled due to a global pandemic), Coach Yabui has set school coaching records for the most Far East champions produced and the most Far East team titles won with 32 Far East champions and 9 Far East titles as of 2023 and he is the second winningest coach in the history of Far East with his team never placing below 2nd in the Far East Individual team result. His Titan teams set a school record for consecutive Far East Individual titles with four (2014, 2015, 2016 and 2017) and tied the Far East record of 6 Far East champions in a tournament twice (2015 and 2016). The 2016 team was also the first in Far East history to win all 5 major titles (Kanto league, Kanto Tournament, Beast of the East, Far East Individual and Dual) in a single season. In 2023, he was appointed to serve as the head high school wrestling coach for the inaugural girls wrestling team at Seisen International School.
In addition to what he has accomplished as the Head Coach of the Titans, Coach Yabui also dedicates his time to promote the sport of wrestling both internationally and domestically.
