In January 1999, Super Delfin announced that due to disagreements with The Great Sasuke regarding the direction of Michinoku Pro Wrestling, he would be leaving the promotion alongside several wrestlers and backstage personnel. On March 4, he officially founded Osaka Pro Wrestling (OPW) in his hometown of Osaka. Starting April 29, OPW produced their first tour, the Spicy Series 1999. The first event took place at the Namihaya Dome – now the Towa Pharmaceutical Ractab Dome – in Kadoma, Osaka and saw the team of Super Delfin, Masato Yakushiji and Naohiro Hoshikawa defeat Dick Togo, Black Buffalo and Violencia.[1]
The promotion held a major flagship event called the Osaka Hurricane each year from 2003 to 2012 and also hosted the fourth edition of the Super J-Cup in 2004, which was the second edition of Osaka Hurricane.
In 2010 Osaka Pro started a close working relationship with American promotion Chikara.
On March 1, 2014, Osaka Pro announced that it would fold on April 20, 2014 due to financial difficulties, after which all of its wrestlers would become freelancers.[2] Osaka Pro later announced that the promotion would continue under new president Yuji Sakagami and wrestlers Kuishinbo Kamen and Takoyakida. The new Osaka Pro Wrestling lost many of the old one's key wrestlers as well as their home base of Nasci Hall Umeda, forcing them to employ a new tour format.[3]
In October 2021, it was announced that Zeus had been appointed as the owner and president of OPW. He became president on July 30, and on August 26, he received a share transfer from former owner Yuji Sakagami. However, he remained under contract with All Japan Pro Wrestling (AJPW) for the rest of the year.[4]
