Title history

Inaugural champion Io Shirai.

The title was created on May 21, 2016, during Stardom's three-day European tour, as the flagship title for a newly established international alliance called the Stardom World Association (SWA) (スターダム・ワールド・アソシエーション, Sutādamu Wārudo Asoshiēshon).^[1][5] Promotions in the alliance include Stardom, British Empire Wrestling (BEW), the French Association Biterroise de Catch (ABC), the Mexican Women Wrestling Stars (WWS) and the Spanish Revolution Championship Wrestling (RCW).^[6] Like most professional wrestling championships, the title is won as a result of a scripted match. The rules of the championship state that only wrestlers from countries other than the reigning champion can challenge it. For example, as long as the title had a Japanese champion, no other Japanese wrestler could challenge for it.^[7] On the same date, Io Shirai became the inaugural champion after defeating Toni Storm in the tournament finals.^[1]

On September 17, 2020, the championship was vacated after the previous titleholder, Jamie Hayter, was unable to travel to Stardom due to COVID-19 restrictions.^[8] On September 17, Bea Priestley won the title by defeating Momo Watanabe.^[9] On January 8, 2022, Syuri vacated the title due to being a triple champion and to focus on the World of Stardom Championship and the Goddesses of Stardom Championship.^[10] Thekla won the vacant title after defeating Mina Shirakawa.^[11] On November 3, Mayu Iwatani relinquished the title in order to pursue after the newly established IWGP Women's Championship.^[12] The title was subsequently abandoned and never mentioned again.
