On September 5th, Pro Wrestling ZERO1 returned to TOKYO SQUARE in Itabashi, where a new member of the roster was added in the form of Koji Doi.

Doi has been competing with ZERO1 since February, taking part in the promotions Fire Festival 2026, and most recently challenged for Junya Matsunaga’s ZERO1 World Heavyweight Championship. Doi started his wrestling career back in 2011 and has past experience working in WRESTLE-1, AJPW, and other independent promotions around Japan.
