Xavier Duval

Xavier started Nihon Tai Jutsu in France in 1998 with Thierry Durand (6th Dan, Seibukan Academy/FMNITAI) and Max Lormeteau (9th Dan, Seibukan Academy/FMNITAI), training with many masters of Nihon Tai Jutsu and other martial arts (Hapkido, Kali, Aikido) across Japan, South Korea and Europe.

After settling in Hong Kong in 2008, he founded Hong Kong Bujutsu Seishinkai in 2012 and has taught there since.

From 2010 to 2024 he trained within Aunkai under Akuzawa Minoru sensei, from whom he received a Menkyo Kyoshi (teaching license). The tanren methods he learned there remain central to Seishinkai’s bujutsu tanren curriculum. He is no longer affiliated with Aunkai.

Xavier’s current practice and teaching in Hong Kong is centered on Kishinkai Aikido — taijutsu and kenjutsu — under the guidance of Leo Tamaki. He continues to teach Nihon Tai Jutsu through seminars outside Hong Kong.
