Cosmic Train, maimai GreeN Theme Song (maimai DX)

All songs

Overview

"Cosmic Train" is the theme song of maimai GreeN, composed by Shoichiro Hirata with vocals by SUIMI and lyrics by Miho Kiriya. It debuted on July 11, 2013 alongside the GreeN version launch, and has remained in the maimai song library across all subsequent versions, a rare longevity for a version-specific theme track. The song pairs Hirata's polished synth-pop production with SUIMI's slightly husky, sweet vocal delivery, creating a bright and catchy sound that the composer has described as "vocal pop with a sparkling feel." Lyrically, the song paints a romantic journey through space, weaving together zodiac signs (ARIES, TAURUS, GEMINI), astronomical imagery (Venus, stars, the cosmos), and the titular cosmic train metaphor, all set to a driving 140 BPM beat. A vogue-style dance PV accompanies the track, adding a stylish visual dimension. Over its lifetime, the song's charts have been revised multiple times across version updates, the Expert chart (designed by 譜面-100号) and Master chart (designed by mai-Star) have climbed considerably in level from their original GreeN ratings, reflecting maimai's evolving difficulty standards. The track later crossed over into SEGA's ONGEKI bright MEMORY in November 2022, expanding its reach beyond the maimai series.

Trivia

Cosmic Train is the designated theme song of maimai GreeN, released on the version's launch day (July 11, 2013).
The song was composed by Shoichiro Hirata, an arranger and producer who has worked with major artists including EXILE, SMAP, Morning Musume, and ℃-ute, and has contributed numerous tracks to music games.
Lyrics were written by Miho Kiriya, while SUIMI handled vocals. Hirata stated he knew from the start that he wanted SUIMI on the track and designed the melody and cosmic theme around her voice.
The lyrics reference three zodiac signs, Aries, Taurus, and Gemini, alongside Venus, stars, and a Ferris wheel floating in the night sky, framing a romantic meet-up as a train ride through space.
Hirata mentioned in the soundtrack booklet that SUIMI has a natural feel for fitting lyrics to melody, and he praised her ability to place syllables with the right phonetic feel exactly where needed.
In its original GreeN incarnation, the highest chart was a Level 10 Master. Over successive version updates, from MURASAKi to UNiVERSE+ to FESTiVAL, the Master chart was repeatedly re-rated, eventually reaching Level 12 (constant 12.5).

The Advanced chart was originally Level 5 and has been adjusted over the years, eventually settling at Level 6 from FESTiVAL onward.
The song originally belonged to the ORIGINAL genre category. It was moved to ORIGINAL & JOYPOLIS in maimai PiNK, then reclassified simply as maimai genre starting from maimai でらっくす PLUS.
Cosmic Train was added to ONGEKI bright MEMORY on November 24, 2022, with chart arrangements by みそかつ侍 (Expert) and Revo@LC supported by 一ノ瀬リズ (Master).
