Ката (формальные упражнения) школы Вадо-рю каратэ-до. Wanshu - Вансю, Вансу.
Из описания к ролику: Masahiro Maruyama, Wado Ryu Renmei member This video was shot at the JKF 38th Tokyo Karate Athlete Championships 2008. Maruyama placed Best 16 out of 93. His
first two rounds he won with Chinto, but lost this round with Wanshu.
Although very sharp, I think the judges thought the pacing was too far
from the standard Wado Wanshu. See his Chinto on KenzenJapan.
