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 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. 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.
