A high-energy rock tribute to Japan's staple grain, "日本の米は世界一" (Nihon no Kome wa Sekaiichi, "Japanese Rice Is the Best in the World") was contributed to maimai by the three-piece band 打首獄門同好会 (Uchikubi Gokumon Doukoukai). Originally released as a single in spring 2015, the year the band marked its 10th anniversary, the song rattles through a celebratory list of donburi bowls (gyūdon, katsudon, tendon…), set meals (sashimi teishoku, karaage teishoku…), and a relentless chorus declaring rice the pillar of the Japanese table. The music video's full version culminates in the shouted pun "米(マイ)! 米(マイ)!", a happy accident that echoes the "mai" of maimai itself. In maimai, the track arrived on December 5, 2017 with MURASAKi PLUS and has since seen its Advanced and Master difficulty levels rise across successive DX versions, reflecting the chart's enduring popularity. The MASTER chart, designed by Jack, packs a dense 706 notes including 110 Slides and 150 Breaks, while the EXPERT chart by サファ太 offers a 10+ level workout. Outside Japan, the title was romanized as "nihon no kome ha sekaiichi" and the artist as "UCHIKUBIGOKUMON-DOUKOUKAI" on Asian English releases.
