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.

A love song by Hey! Say! JUMP where a sweet, pop melody pairs perfectly with slightly biting lyrics.

Released in May 2023 as their 33rd single, it was included as a double A-side along with “Uraomote.” It was chosen as the theme song for the drama “Ousama ni Sasagu Kusuriyubi,” starring member Ryosuke Yamada.

It’s a wedding song that captures a frustrating yet adorable feeling of love: someone who can’t be honest and acts tsundere, but whose feelings are real.

Its positive message—let’s create the best story even if we’re the worst pair—makes you feel happy just by listening.

The easy-to-learn choreography is also a draw, making it perfect for livening up happy occasions like weddings.

One of its charms is the sparkling feel of the arrangement, with beautifully resonant strings.

Just from the sound alone, you can picture a snowy scene, feel the flutter of being in love—those are the impressions it gives.

Marking the close of their 10th anniversary year, the song was later included on the album “SENSE or LOVE.” Filled with straightforward feelings for a destined someone, it seems like the perfect song to listen to around Valentine’s Day or on a winter day spent with someone special.

This piece could be called a hidden gem by AKB48, a song about pure love that asks for nothing in return.

Riding on a driving, fast-paced band sound, it delivers a heartfelt message in classic idol-pop fashion.

Originally included as a B-side to the single “RIVER,” released in October 2009, it gained such passionate support from fans that it proudly took 2nd place at the following year’s Request Hour.

It was also used as the theme for the Wii game Tōmajiden commercials, so some listeners may already find it familiar.

The bright vocals from the Under Girls, including Aki Takajo, give listeners a powerful push forward.

If you listen when you’re feeling down or when you want to cheer someone on with all your might, you’re sure to get a dose of positive energy.

Give it a listen when you’re chatting about love with friends, or when you can’t quite put your feelings for someone special into words.

This AKB48 song paints a romantic scene that makes you want to head to the chilly seaside in lingering-February cold.

It’s memorable for lyrics that liken carefree frolicking by the winter ocean to a mermaid, turning even the cold spray of the waves into shared memories.

Performed as a unit song with Azuki Yagi on vocals at a theater show in December 2024, it was later included on the album “AKB48 ~studio recordings collection~ AKB48 18th Stage ‘Koko Kara da,’” released in December 2025.

This work is a bittersweet love song that captures feelings of affection so strong they make even selfish behavior seem adorable.

It’s the perfect track for gazing out at the quiet winter sea and sinking into a sentimental mood.
