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.

Cherry blossoms, an old school building, a uniform button—packed with such scenes of spring, this =LOVE song is the group’s fifth single, released in April 2019.

It reached No.

2 on the Oricon Weekly Chart and earned a Gold certification from the Recording Industry Association of Japan.

The track was also featured in Mr.

Fusion’s programming school “Prosta Kids” commercial.

In its story-driven music video, the turmoil of parting with friends is portrayed with care.

It’s recommended not only for those approaching graduation, but also for anyone who struggles to put their gratitude for friends into words.

Graduationkyandīzu

Introducing a classic song about youthful farewells by the legendary 1970s idol group Candies.

Included on the album “Toshishita no Otokonoko,” released in April 1975, this track gently weaves the bittersweet feelings of two people who will be separated after graduation.

Unspoken emotions and memories of walking home in school uniforms evoke the aching stirrings of an unfinished love at the end of youth.

Ran Ito serves as the main vocalist, delivering the song with a slightly mature tone that leaves a strong impression.

Used as the theme song for the youth drama segment within the TV show “Migoro! Tabegoro! Waraigoro!,” it etched itself into the hearts of many viewers together with the visuals.

It’s a number we especially recommend to those who have experienced a love that ended as just friends or carry feelings they were never able to express.

A 2nd single by 22/7 that portrays a secret longing for an upperclassman at an all-girls school.

Released in April 2018, the song delicately weaves the feelings of a faint, bittersweet crush.

It tells of parting with a senior who is leaving the club, the image of a white blouse turning translucent in backlight, and a gently drifting scent.

While carrying a love that can’t be told to anyone, the story unfolds up to the moment the senior embraces her, tightening the chest with every scene.

This work leaves the ache of an unfulfilled first love, yet also a lingering sense of solace.

It’s a song that quietly stands by those who cannot confide their feelings for someone of the same gender.

Love letterHey! Say! JUMP

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.

For anyone experiencing a one-sided love and finding it hard to be honest, this is a work you should definitely hear.
