A breakup song sung by an idol. A collection of bittersweet love songs.

Among the songs sung by idols, there are so many love songs, aren’t there?

In this article, we’ll focus on breakup songs among those many love songs.

Even when we say “breakup songs,” the stories behind them vary: songs about breaking up after dating, songs about confessing and being rejected, songs about unrequited love that ended before the feelings could be conveyed, and so on.

So as you listen to the songs we’re about to introduce, be sure to read the lyrics as well, and take your time to savor the stories and bittersweet emotions woven into each one.

This is a ballad that captures the frustration of being unable to take that first step in love, alongside the pure feelings you hold for someone.

Its structure—passing the vocals along over delicate piano and strings—seems to carefully trace the subtle shifts of a wavering heart.

Many listeners will likely feel a tightening in their chest at the image of someone entrusting their overflowing feelings to a letter, lacking the courage to speak directly.

It’s the coupling track included on the standard edition of the single “encore,” released in May 2025.

While the title track drew attention as a TV drama theme, this song quietly won fans over as a hidden gem.

It’s a piece that stays close on nights when you want to keep thinking of someone in silence.

Debuting in 2023 and winning the Best New Artist Award at the Japan Record Awards in just one year, Boku ga Mitakatta Aozora are set to release their 7th single in December 2025.

The title track is a classic winter first-love song with lyrics by Yasushi Akimoto and music by Daisuke Shirai.

It tells a poignant story of a boy who is captivated by a girl he glimpses by chance on a train platform, and, seeing her as delicate like a fairy, keeps searching for her every morning.

Vivid scenes—winter uniforms, scarves, and crowded trains—tug at the heart, and it’s impossible not to empathize with the protagonist, who senses the love may never be fulfilled yet still engraves the feeling of “I truly fell in love.” The music video, featuring Ami Kanazawa in the center playing a transfer student, has drawn attention for its direction that shifts between reality and imagination.

Highly recommended for anyone who wants to revisit a softly bittersweet page of youth.
