Which programmer is listed between Takafumi Masaoka and Kosuke Teshima?

Naoki Masuda is the programmer listed between Takafumi Masaoka and Kosuke Teshima in the Rhythm Heaven Groove credits.

Those credits identify the three as programmers, separate from the game's artists and composers. Kazuyoshi Osawa is credited as director, while Tsunku is among the producers and also contributes to the music.

Rhythm Heaven Groove is the fifth entry in Nintendo's Rhythm Heaven series. It was developed for Nintendo Switch and retains the series' emphasis on short rhythm games driven mainly by audio cues.

A common mix-up is confusing the programming credits with the artist or composer lists. Kyohei Seki appears among the artists, while Rei Kamiya and Haruki Matsumoto are listed among the composers, making Naoki Masuda the only answer that fits the question.
