# World of Stardom Championship

The World of Stardom Championship (ワールド・オブ・スターダム王座, Wārudo Obu Sutādamu Ōza) is a women's professional wrestling world championship owned by the World Wonder Ring Stardom promotion. The title, which is situated at the top of Stardom's championship hierarchy, was introduced on June 26, 2011, and the inaugural champion was crowned on July 24, 2011, when Nanae Takahashi defeated Yoko Bito in the finals of a four-woman tournament.

### 2015 tournament

On February 22, 2015, during a title match between the current champion Yoshiko and Act Yasukawa, Yoshiko began shooting on Yasukawa, legitimately injuring her, with the match having to be ended prematurely. Yasukawa was diagnosed with fractured cheek, nasal and orbital bones, which would require surgery. Three days later, Yoshiko was stripped of the title. On March 29, Kairi Hojo defeated Io Shirai in the finals of a four-woman tournament to win the vacant championship.

On September 24, 2017, during a match between the current champion Mayu Iwatani against Toni Storm, the title changed hands which was unplanned, as Iwatani legitimately dislocated her elbow, prompting the referee to stop the match and award the championship to Storm.

### Origin and belt design

The title is often referred to simply as the "Red Belt", a name famously used by All Japan Women's Pro-Wrestling (AJW) to refer to its WWWA World Single Championship (of which Takahashi had been the last titleholder back in 2006). The title belt was crafted by American company Top Rope Belts, with a conscious decision to imitate the AJW title belt in terms of its color, with Stardom president Rossy Ogawa referring to the promotion's heyday as the "Golden Age of Joshi Puroresu". The title has also been defended in Mexico and France.

## Reigns

As of March 13, 2025, there have been 19 reigns between 14 champions and two vacancies. Nanae Takahashi was the inaugural champion, as well as the longest reign at 602 days.
