Pro Wrestling Zero1 (プロレスリングゼロ1? Puroresuringuzerowan) (stylized as Pro Wrestling ZERO1), formerly known as Pro Wrestling Zero-One and Pro Wrestling Zero1-Max, is a Japanese professional wrestling promotion founded in 2001. It was affiliated with the National Wrestling Alliance (NWA) from 2001 until late 2004 and briefly reaffiliated in 2011.
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.
Zero1 has had working agreements with Pro Wrestling Noah, All Japan Pro Wrestling, New Japan Pro Wrestling, RIKIPRO, Hustle, Big Mouth Loud, King's Road and Dragondoor (now El Dorado Wrestling) which enabled Zero1 wrestlers to challenge for and hold the other promotions' titles.
Zero1-Max On November 30, 2004 Hashimoto gave up ownership of the promotion, telling the press that due to financial problems he had decided to step away from the company. A new parent company "First On Stage" was formed consisting of President Yoshiyuki Nakamura, Ring Announcer Oki Okidata, Shinjiro Otani and a company named Baltic Curry. The promotion was renamed Pro Wrestling Zero1-Max with Otani and Nakamura taking over the general operations.
Among the major changes to the federation's structure was joining the AWA Superstars of Wrestling (now Wrestling Superstars Live) as the only Japanese member. At the same time the owner of the company's National Wrestling Alliance promoting license, New Japan Pro Wrestling, took the license back for their own use.
On September 12, 2006, Zero1-Max joined 12 other pro wrestling companies and joined the Global Professional Wrestling Alliance (GPWA), a professional wrestling alliance that fosters an environment of cooperation rather than competition. The alliance also occasionally puts on "Super Shows" where all the promotions send fighters to compete representing their own companies under the GPWA banner. Pro Wrestling Noah's CEO Mitsuharu Misawa was inaugurated as the first Chairman of the new alliance, with Zero1-Max's Yoshiyuki Nakamura announced as the company's President.
In 2008, the promotion shortened the name to Pro Wrestling Zero1. In 2011, the promotion returned to the NWA as their Japanese territory. In March 2011, NWA presented Zero1 with the NWA Pan-Pacific Premium Heavyweight Championship in celebration of the promotion's 10th anniversary. In July, Daisuke Sekimoto won the Fire Festival to become the first champion.
Expansion In 2012, an Australian division of Zero1 known as Zero1 Pro Wrestling Australia opened in Adelaide taking over what was known as NWA Pro Wrestling. At the beginning of 2014 the relationship ended and the promotion is now known as Wrestle Rampage. Zero1 Hong Kong branch opened in June 2012 after Jason New returned to Hong Kong from Zero1 earlier that year. Pro Wrestling Zero1 Mexico opened its branch in September 2012 after [[International Pro Wrestling Alliance] united with Zero1 Japan. In 2013, Yoshiyuki Nakamura opened a new division of Zero1 in Belarus.
On December 17, 2013, Zero1 announced a corporate restructuring taking place at the start of the new year.
On September 16, 2016, Dream On Stage was announced as Zero1's new parent company. Also announced was a partnership between Zero1 and Akebono's Ōdō company.
On May 22nd, 2017, it was announced that Pro Wrestling Zero1 became the Japanese Affiliate Federation to the United Wrestling Network.
