The JWP Openweight Championship was a women's professional wrestling championship owned by the JWP Joshi Puroresu promotion. The championship, which was situated at the top of JWP's championship hierarchy, was introduced on December 2, 1992, when Dynamite Kansai defeated Cutie Suzuki in a tournament final to become the inaugural champion. At the time of JWP Joshi Puroresu's folding in April 2017, the JWP Openweight Championship was the oldest active title in all of joshi puroresu.[1]
Like most professional wrestling championships, the title was won as a result of a scripted match. There were thirty reigns shared among nineteen different wrestlers. The title was retired on April 2, 2017, when JWP Joshi Puroresu went out of business. That same day, Hanako Nakamori won the final match contested for the title, making her third successful defense against Tsubasa Kuragaki.[2] [3]
On December 2, 1992, Dynamite Kansai became the inaugural JWP Openweight Champion by defeating Cutie Suzuki. On October 15, 1995, Kansai would defeated Suzuki once again to win the title, which was previously vacated. On November 28, 2004, after the championship was vacated once again, Azumi Hyuga won it by defeating Kayoko Haruyama in a tournament final. On September 19, 2010, at JWP Revolution, the 15th champion Kaori Yoneyama successfully defended her title against Emi Sakura in a Hair vs. Hair match, forcing Sakura being shaved bald.[4] Sakura would later win the championship on October 28, 2012, after defeating Kayoko Haruyama.
On April 2, 2017, at JWP's 25th Anniversary show, which was JWP's last show as JWP closed doors, the championship was deactivated with Hanako Nakamori being the last champion, with a final successful title defense against Tsubasa Kuragaki.[2] [3]
Over the championship's 24-year history, there have been 30 reigns between 19 champions and two vacancies. Dynamite Kansai was the inaugural champion, while Hanako Nakamori being the last. Arisa Nakajima and Azumi Hyuga share the record for most reigns at four. Kayoko Haruyama's first reign is the longest at 719 days, while Kyoko Kimura's reign is the shortest at 25 days. Mayumi Ozaki is the oldest champion at 46 years old, while Kansai is the youngest at 22 years old.
