Rhythm Heaven Groove Tops 1 Million in Cumulative Sales in Japan, Claims the Weekly No. 1 Spot for the 7th Time with 24,756 Units — Onimusha: Way of the Sword's Two Versions Land in the Top 5 in Week Two (Sept. 7–13)

Rhythm Heaven Groove claimed the weekly No. 1 spot for the seventh time with an estimated 24,756 units sold, and its cumulative sales in Japan have now topped 1 million units.

The tracking period ran from September 7 to September 13, 2026. The figures are Famitsu’s weekly sales estimates for Japan. The game, published by Nintendo for Nintendo Switch, has players work through a series of short minigames, tapping buttons in time with the music. It launched on July 2, the same day as in Japan, and its cumulative sales in Japan passed 1 million units roughly ten weeks later.

Second and fifth place went to Onimusha: Way of the Sword, now in its second week on sale. The PlayStation 5 version sold 19,654 units, and the Nintendo Switch 2 version sold 7,070. Famitsu counts sales by platform, so the two versions of the same game appear as separate entries. The game launched on September 4 and topped 1 million units worldwide on its first day.

Third place went to Splatoon Raiders (Nintendo Switch 2) with 8,163 units, and fourth to Tomodachi Life: Living the Dream (Nintendo Switch) with 7,607. Minecraft (Nintendo Switch) followed in seventh with 3,324 units, and Mario Kart World (Nintendo Switch 2) placed eighth with 3,141.

Two titles are new entries this week. Sixth-place Gakkou de Atta Kowai Hanashi to Tsukikomori (Nintendo Switch, 3,683 units) bundles together two horror adventure games originally released for the Super Famicom in the 1990s. Tenth-place ROMANCE OF THE THREE KINGDOMS XIV Complete Edition (Nintendo Switch, 2,797 units) is a complete edition marking the series’ 40th anniversary.

The ninth-place finisher, Village in the Shade (Nintendo Switch 2, 2,837 units), will be published by NIS America, Inc. on October 27.

Most of the titles in the top 10 are already available outside Japan. Tomodachi Life: Living the Dream launched on April 16, while Onimusha: Way of the Sword, Splatoon Raiders, and Mario Kart World all launched worldwide simultaneously. ROMANCE OF THE THREE KINGDOMS XIV, along with the expansion pack ROMANCE OF THE THREE KINGDOMS XIV: Diplomacy and Strategy Expansion Pack, is available on Steam.

In hardware, Nintendo Switch 2 led with 28,341 units sold. PlayStation 5 Digital Edition followed with 7,082 units, then Nintendo Switch Lite with 3,791, and Nintendo Switch – OLED Model with 2,913.
