Shinya Hashimoto
The promotion was founded by former New Japan Pro-Wrestling (NJPW) stars Shinya Hashimoto and Shinjiro Otani. In 2000, Hashimoto proposed an independent promotion within NJPW called New Japan Pro-Wrestling Zero, but the idea was shot down. When Hashimoto was fired by NJPW in November 2000, he registered the Pro Wrestling Zero-One name.
