KOKIA Popular Song Rankings [2026] (1–10)

Thank you…KOKIA1rank/position

“Arigatou…” released in 1999 by singer-songwriter KOKIA, is a song filled with gratitude for a loved one who has been lost.

Sung in KOKIA’s straightforward, warmly resonant voice, its simple yet powerful lyrics convey deep appreciation for someone dear and a resolve to live strongly from here on.

It frees listeners’ hearts from the pain of loss.

Even the “thank you” left unsaid will surely reach them if you keep thinking of it.

Why not listen while looking up at the sky, thinking of the one you love?

Unchanging Things ~since 1976~KOKIA2rank/position

KOKIA’s singer-songwriter number “Kawaranai Koto ~since 1976~” conveys the feeling of telling those who have supported you, “Watch me as I do my best from here on.” Released in 2003, the song was chosen as the theme for the drama “Beloved.” When graduating and leaving the teachers and parents who have cared for you, expressing gratitude is of course important.

But the lyrics also depict the idea that not only saying thank you, but showing through your actions that you’ll work hard from now on is a true way to repay those who helped you.

Why not listen to this song and feel a form of gratitude expressed not just in words, but in attitude?

"Only One Feeling" GUNSLINGER GIRL

This is the song used for the opening of GUNSLINGER GIRL -IL TEATRINO-, for which the popular singer-songwriter KOKIA handled all the lyrics and composition.

Although the anime itself is relatively niche, the opening is often uploaded to video sites, so many people have probably heard it.

In particular, the chorus has a catchy rhythm and a melody that sticks in your head, so you might find yourself humming it before you know it—another reason this song is so popular.

The true soundKOKIA5rank/position

This is a song by KOKIA that calls on listeners to tune in to their true inner voice when they feel they’re losing sight of the meaning or purpose of life.

It urges us to face the part of ourselves that gets swept along by a superficial world and to reexamine our fundamental values.

With a translucent vocal and a beautiful piano melody that soaks into the heart, the piece feels like a cry from the depths of the soul.

Included on the album “moment,” released in May 2011, this work stands as a symbol of KOKIA’s musical maturity and has deeply moved many listeners.

It’s a song that offers companionship to those who feel lonely or anxious and are on the verge of losing their sense of purpose, and to anyone seeking a path that is true to themselves.
