僕の和風本当上手 (Boku no Wafuu Hontou Jouzu, "My Japanese Style is Really Good") is a crossover track that originated in the rhythm game Muse Dash, where it appeared in the "MUSIC快楽天" (Music Kairkuten) song pack. The song was ported to maimai as part of a Muse Dash themed area (Muse Dashちほー) released during the DX FESTiVAL PLUS era on April 14, 2023, and remains available in all regions including Japan, International, USA, and China. The piece was composed by iKz under the alias ボス (Boss). Its title is a playful twist on the internet meme phrase "君日本語本当上手" (Your Japanese is really good), swapping "日本語" (Japanese language) for "和風" (Japanese-style). This self-aware humor carries through to the game's collection system, where earning a FULL COMBO on any difficulty unlocks the title "君日本語本当上手", a direct callback to the original meme. Musically, the track begins at a calm 120 BPM before jumping to 180 BPM for the remainder, a BPM-shift structure shared in maimai with songs like Halcyon and 竹. The chart design continues the joke: the Master difficulty was penned by 僕の檸檬本当上手 ("My Lemon is Really Good"), a pseudonym that mirrors the song's own title structure by swapping out "和風" for "檸檬" (lemon), while the Expert chart was designed by はっぴー.
