おても☆Yan is a maimai original arrangement of おてもやん (Otemoyan), a traditional Japanese folk song from Kumamoto Prefecture, performed by longtime Sega vocalist Takenobu Mitsuyoshi (光吉猛修). It joined the maimai ORANGE lineup on February 19, 2015 as a shared song, initially only obtainable by tapping an Aime card at the Sega booth during JAEPO 2015, or by playing alongside someone who had already unlocked it. General availability arrived with the ORANGE PLUS update on March 19, 2015. At 90 BPM, the track is the third entry in maimai's folk song arrangement series, following Tankō Bushi and So-ran Bushi. Mitsuyoshi's concept fused the traditional folk melody with a light J-rap / hip-hop sensibility popular in mid-2010s Japanese music, while preserving the original folk vocal delivery. Professional folk singers and a shinobue (Japanese transverse flute) player were brought in for the recording, with the shinobue's free-form improvisations adding an organic counterpoint to the beat-driven arrangement. Mitsuyoshi later noted that the tricky structure of the original Otemoyan made it difficult to arrange at first, but the addition of live instruments unlocked creative ideas that shaped the final version. The song's in-game genre has shifted across maimai versions: originally categorized as VARIETY, it moved to ORIGINAL & JOYPOLIS, then ORIGINAL, and finally settled under the maimai genre in the DX era. Its MASTER chart, designed by 譜面-100号 (Fumen -100 gou), holds a notable place in maimai chart history as the first to feature very short hold notes, nicknamed HOLDTAP by the community, that behave like taps rather than holds, punishing any instinctive press-and-hold. This gimmick pattern later resurfaced in several other charts, most famously Axeria. The chart's level has been revised multiple times across version updates, rising from 11 in ORANGE to 13 in the current DX era.
