JWP Joshi Puroresu , also known as JWP Project or simply JWP, was a Japanese joshi puroresu promotion, founded in 1992 as a splinter promotion of Japan Women's Pro-Wrestling. Celebrating its 25th anniversary at the time of its folding in 2017, JWP was the oldest joshi puroresu promotion in Japan and its Openweight Championship was the oldest championship in all of joshi. Command Bolshoi, who had worked for the promotion since the beginning, served as the final president of JWP. The promotion's slogan was "Pure Heart, Pure Wrestling".

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.
