Jun Kasai

Personal life Kasai is married to his wife Michiyo; the couple have a daughter together. Kasai also has a son, Hinata, from a previous relationship. In July 2025, DDT Pro-Wrestling revealed Hinata had been training for them. He made his debut the following month at Wrestle Peter Pan 2025.

He was born in Hokkaido and now lives in the mainland, but claims on his official website that he is from "Hiladelhia, America" as a joke; he has described Philadelphia as his second homeland. While Kasai wrestled in the United States, he was a lodger in Matthew Prince, better known as the wrestler Wifebeater's house. He has described Prince as a real madman, unlike many deathmatch wrestlers who are in fact gentlemen outside the ring.

Other media Kasai is the subject of a documentary called Kyo-En. The documentary was released in 2021. In 2025, videogame creator Hideo Kojima praised the film.

Championships and accomplishments Since 2005, there have been "razor blade board" deathmatches in BJW, Apache Pro Wrestling and Freedoms, and all of them have involved Kasai.
