Wonder of Stardom Championship

The Wonder of Stardom Championship (ワンダー・オブ・スターダム選手権, Wandā Obu Sutādamu Senshuken) is a women's professional wrestling championship owned by the World Wonder Ring Stardom promotion. The title, which in Stardom's championship hierarchy is situated as the secondary title behind the World of Stardom Championship, was introduced on June 26, 2011, and the inaugural champion was crowned on July 24, 2011, when Yuzuki Aikawa defeated Yoshiko in a decision match. The title is often referred to simply as the "White Belt", a name famously used by All Japan Women's Pro-Wrestling (AJW) to refer to its All Pacific Championship. The title belt was crafted by American company Top Rope Belts based on designs sent by Stardom, 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 original title belt was awarded to undefeated inaugural champion Yuzuki Aikawa, when she retired from professional wrestling on April 29, 2013. It was replaced that same night by a second identical title belt.

Originally, only wrestlers officially signed to Stardom were eligible to challenge for the title, but this rule was abandoned in 2013, when Dark Angel and Yuhi were allowed to challenge for the title. When Santana Garrett won the title in November 2015, she started defending it in the United States, alongside the NWA World Women's Championship. Her six defenses on the American independent circuit were also recognized by Stardom.

Like most professional wrestling championships, the title is won as a result of a scripted match. There have been eight reigns shared among seven wrestlers. Kairi Hojo is the current champion in her first reign.
