Rhythm Heaven Groove debuted at No. 1 on Famitsu’s Japanese sales charts. Famitsu’s weekly tracking placed Nintendo’s new Switch release above every other game during its launch week.
The debut covered the week of June 29 through July 5, 2026, after Groove launched in Japan on July 2. Famitsu reported 393,378 physical copies sold in that opening chart period, making it the week’s leading title as well as the strongest new release.
The wording can cause a mix-up between Famitsu’s review scores and its sales charts. Famitsu is both a major Japanese video-game magazine and a source of widely cited Japanese sales rankings. Nintendo Dream, V Jump and Dengeki are also familiar Japanese game publications, but they are not the magazine identified for Groove’s No. 1 debut in this question.
