Tatsuhito Senga is a Japanese professional wrestler better known by his ring names Hercules Senga and Banana Senga (バナナ千賀). He currently wrestles as a freelancer in the Japanese independent circuit and as a regular in both Michinoku Pro Wrestling and Big Japan Pro Wrestling (BJW).

Michinoku Pro Wrestling is a Japanese professional wrestling promotion founded by The Great Sasuke on October 1, 1992. It was the first independent wrestling promotion in Japan to not base its operations in Tokyo, but rather in Morioka, Iwate. Since the promotion is primarily focused on the Lucha libre style of wrestling, many of their wrestlers don masks and special motifs as they compete in the ring. However, Michinoku Pro has accepted wrestlers from various styles and backgrounds over the years. In 2003, Sasuke left the running of the promotion to Jinsei Shinzaki.
