Which artist is listed as Rhythm Heaven Groove's lead art designer?

Ko Takeuchi is listed as Rhythm Heaven Groove’s lead art designer. In the game’s Wikipedia credits, he appears under the artists heading, alongside Kyohei Seki, while the article’s development section identifies Takeuchi as the art director.

Takeuchi is a longtime Nintendo collaborator whose work is especially associated with the WarioWare series. That background makes him a natural fit for Groove, a game built around sharply contrasting visual styles, comic timing, and short rhythm challenges.

A common mix-up is confusing the game’s artists with its composers. Koji Kamada is listed among the composers, Kazuyoshi Osawa is the director, and Kouichi Kawamoto is listed among the producers. The credits therefore distinguish these roles rather than presenting several interchangeable art-design answers.

Groove continues the series’ tradition of turning simple rhythmic inputs into visually unusual minigames. Its art direction supports that variety instead of forcing every challenge into one uniform visual style.
