Rhythm Heaven Groove sold 393,378 copies in its first week in Japan, according to Famitsu.
The figure refers to boxed physical sales recorded in Famitsu’s Japanese weekly software chart for the week covering the game’s launch. Groove debuted at No. 1, giving the long-running rhythm series its strongest opening reported in Japan.
That number should not be confused with worldwide sales, digital purchases, shipments, or lifetime sales. Famitsu’s weekly retail figures are commonly cited as physical sell-through data, so the total number of copies actually sold across all formats may be higher.
Groove’s result was notable because it followed a long gap since the previous new Rhythm Heaven game. The earlier Rhythm Heaven Megamix opened in Japan at about 158,000 copies, making Groove’s debut substantially larger. The 393,378 figure is therefore a launch-week statistic, not a final sales total.
