true blue / yearning…ZONE
The opening theme of the anime Astro Boy (Tetsuwan Atom).
In their early days, they were marketed not as a band or an idol group but as a “bundle,” but later became famous as a skilled all-girl band.
They even performed at the Budokan for their final live show, after which the band disbanded.
Andromedaaiko
Aiko’s 13th single, which ranked 3rd on the Oricon weekly chart, 9th monthly, and 74th for the year.
Tied in as the theme for Glico Dairy’s “Café au Lait” commercial, this heartbreak song is achingly poignant: the lyrics tell of a girl who once prided herself on her sharp eyesight, yet couldn’t perceive the changes in his heart—something vision can’t catch—and now, with tears blurring her view, even finding him before her is difficult.
SHALL WE LOVE ?gomattou
This is the only single from a limited-time unit consisting of Aya Matsuura, Miki Fujimoto, and Maki Goto—three artists who were showcasing their talents as solo singers within Hello! Project at the time.
It’s a cool, weighty dance number that leans more toward singer sensibilities than typical idol vibes.
Summer MemoriesKetsumeishi
The seventh single by Ketsumeishi, released on July 16, 2003.
Its light, upbeat rhythm captures the crisp, refreshing feel and cheerful vibe of summer.
The beach-shot music video, presented in reverse playback, showcases Ketsumeishi’s signature playful spirit.
With this track, they made their second appearance on Music Station and reached No.
2 in summer song rankings, reflecting just how strong their momentum was at the time.
Time after time ~In the City Where Flowers Dance~Kuraki Mai
The theme song of the anime film Detective Conan: Crossroad in the Ancient Capital.
The lyrics feel as if they’re inspired by springtime in Kyoto, and when you listen to it while thinking of the Kyoto we live in, the song takes on a different look.
It’s a wonderful track that lets you feel the spirit of Wa (Japanese harmony) all in a single song.
