Overview

ハム太郎とっとこうた (Hamtaro Tottoko Uta) is the opening theme song of the long-running TV anime とっとこハム太郎 (Tottoko Hamtaro), known internationally simply as Hamtaro, which aired from 2000 to 2006. The original recording was performed by ハムちゃんず (Hamuchanzu), a vocal group formed for the anime series. For its inclusion in maimai でらっくす PLUS (DX PLUS) on January 23, 2020, the song was re-recorded as a cover by 光吉猛修 (Takenobu Mitsuyoshi), a celebrated Sega sound creator and vocalist whose unmistakable voice powered the soundtracks of Daytona USA, many Sega arcade hits, and even previous maimai appearances. His cover gives the child-friendly tune a characterful, enthusiastic delivery that stands apart from the original. The song's upbeat, cheerful melody and simple lyrics about friendship and daily adventures capture the warmhearted spirit of the Hamtaro franchise. Within maimai, however, this innocent exterior hides some of the more demanding charts in the POPS&アニメ category. The Re:Master chart (level 12+, constant 12.8), designed by はっぴー, packs 597 notes with a notably high density of Touch notes (137) and Break notes (13), creating a playful but intense challenge that contrasts sharply with the song's gentle aesthetic. The Master chart underwent multiple level revisions across maimai versions, starting at level 11 in DX PLUS, rising to 11+ during Splash through FESTiVAL, and finally settling at level 12 from FESTiVAL+ onward, reflecting ongoing community re-evaluation of its difficulty. An 宴 (Utage/Party) chart was added on March 13, 2025, further expanding the song's high-difficulty offerings.

  • The title ハム太郎とっとこうた is a portmanteau fusing the character name ハム太郎 (Hamtaro) with the anime's distinctive 'とっとこ' motif and うた (uta, meaning song), essentially translating to 'Hamtaro's Scurry-Along Song.'

  • DX Collection titles reference memorable phrases from the anime: unlocking '今日はとっても楽しかったね。明日はも~っと楽しくなるよね。ねっハム太郎♪' requires playing with two or more players, mirroring the show's themes of friendship.
  • The Expert chart (level 8) was designed by 小鳥遊さん, the Master (level 12) by ぴちネコ, and the Re:Master (level 12+) by はっぴー, giving the song three distinct charting styles across its upper difficulties.
  • Despite being a cover of a children's anime theme, the song's high-level charts are considered staple picks for players seeking to challenge Touch-note and density-heavy patterns within the POPS&アニメ category.
