Yasukawa was diagnosed with fractured cheek, nasal and orbital bones, which would require surgery.^[6] Three days later, Yoshiko was stripped of the title.^[7] On March 29, Kairi Hojo defeated Io Shirai in the finals of a four-woman tournament to win the vacant championship.^[8]

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).^[1][10][11] The title belt was crafted by American company Top Rope Belts,^[12] 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".^[13] The title has also been defended in Mexico and France.^[14][15][16]

Reigns

As of August 25, 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. Natsuko Tora has the shortest reign at 34 days. Io Shirai, Mayu Iwatani and Tam Nakano have the most reigns at two. Tam Nakano is the oldest champion at 36 years old, while Yoshiko is the youngest at 21 years old.

Saya Kamitani is the current champion in her first reign. She won the title by defeating Tam Nakano at Stardom Dream Queendom on December 29, 2024.
