I, who am a big fan of Tak Sakaguchi, joined his talk show held in Tokyo on November 9th in 2019. He demonstrated some of his techniques precisely and this footage includes some parts of video I shot. Just for the information, he is drunk a bit in this video. The host (right) is Yuji Shimomura: www.imdb.com/name/nm1647538/ Tak Sakaguchi has his own SNS accounts. Let's follow/register them to get the latest information on him!

The term “wave” is usually used (and probably created) by Tak and his master Yoshitaka Inagawa.
