BEGIN Japanology Professional Wrestling In Japan プロレス
This is the main episode, as far as I can tell.
NHK BEGIN Japanology Season 6 - Ep15: Japanophiles - Kenny Omega
Kenny Omega is a professional wrestler enjoying a successful career in Japan. As well as embracing the unique appeal of Japanese pro-wrestling, he is also a fan of Japan's popular culture. An ardent fan of manga, anime and video games, Omega even makes use of pop culture motifs in his wrestling moves - which are sometimes performed outside the confines of the ring.
