World Woman Pro-Wrestling Diana

World Woman Pro-Wrestling Diana (ワールド女子プロレス・ディアナ) often abbreviated simply as Diana is a Japanese joshi puroresu or women's professional wrestling promotion based in Kawasaki, Kanagawa, Japan. It was founded by Kyoko Inoue in 2010.

History
On July 29, 2010, Kyoko Inoue, who had left NEO Japan Ladies Pro-Wrestling, established World Women's Pro-Wrestling Diana Co., Ltd. with the aim of launching a professional wrestling organization. Kaoru Ito, who at the time was a junior at All Japan Women's Pro-Wrestling, organized the first event of the promotion, the "Diana Debut Show" on April 14, 2011. Furthermore, Ayako Sato joined the company for the first event. In the process Diana accepted two new trainees and they also recruited athletes from abroad, even contracting American wrestlers. In the beginning, their business was going well but athletes and trainees who belonged to other promotions left one after another. Their training base, "Komazawa World" arena was closed down and they had to reconsider their tour style and relocating. In April 2018, they moved their dojo (a martial arts gym and a training base) to Kawasaki city, Kanagawa Prefecture.

In 2012, it was announced that the dojo would be relocated. In the background, the Komazawa World Arena was jointly owned by Inoue and Kagoo, the director who resigned in June (the top page of the Komazawa World Arena official website specified "Kagoo and Inoue" as contact information). The opening of the new dojo was announced at the end of September, but the scheduled date has passed without any new information. After that, instead of the canceled "Arena Match", the Kitazawa Town Hall was used as the main venue, and the performance was held once a month from December. Even after Diana withdrew, Komazawa World Arena remained and there was talk of holding a performance, but it was closed without being realized. Affiliated players who lost their dojo were practicing at Pro Wrestling Zero1's dojo, the "Takeshiba Colosseum " and shoot boxing gyms.

Over the years, the promotion has established partnerships with various promotions from the Japanese independent scene. They started a professional relationship with World Wonder Ring Stardom at the beginning of 2022, sending various wrestlers from the roster to compete in rookie-based pay-per-views promoted by the latter promotion under the brand of "New Blood". Diana was first represented by Nanami and Haruka Umesaki at Stardom New Blood 1 on March 11, 2022.
