[2026] Summer songs that squeeze your heart with bittersweet feelings: classic, soul-stirring summer hits (41–50)
summer festivalWhiteberry
It’s Whiteberry’s biggest hit and a classic summer song loved across generations.
Its addictive melody makes you want to listen to it every summer, and the lyrics—describing how someone important is no longer by your side—are heartbreakingly poignant.
While it has a refreshing, summery feel, it also conveys the loneliness of not having the person you wanted beside you this summer.
It’s a song I especially recommend to anyone experiencing a breakup or an unrequited love.

fireworksaiko
There may not be many people who associate this song with a bittersweet summer vibe.
The reason it’s called a bittersweet summer song lies in what prompted Aiko to write it.
At the time, she was so busy that she couldn’t even make it to the annual fireworks festival she used to go to with friends, and from her longing to say “I want to go see the fireworks,” this song was born! When you hear that story and read the lyrics again, don’t you feel a wave of wistfulness? Some of you might have had a similar experience.
Like this song, isn’t it nice to feel the melancholy of summer through the story hidden behind a bright melody?
balladKetsumeishi
Ketsumeishi is known for many uplifting summer songs, but this track is a gentle piece packed with pure heartache.
Released in 2011 as Ketsumeishi’s 21st single, “Ballad” is truly a gem themed around an unattainable love.
On nights when you can’t see the person you love and your thoughts keep circling back to them, all kinds of feelings rush through you.
It’s a song that tenderly and sentimentally captures those nights that anyone might experience.
A perfect companion for a summer night.
Tears Flowing EndlesslyNatsukawa Rimi
The title “Nada Sōsō” is Okinawan dialect meaning “tears fall and spill over.” Famous across generations, this song is well known for having lyrics by Ryoko Moriyama and composition by BEGIN, and there are versions performed by Moriyama and by BEGIN as well.
Written about Moriyama’s late older brother, the song evokes sadness and poignancy, yet by the end it leaves you with a very gentle feeling.
It’s also a classic song of the summer.
I want to be your lover.Abe Mao
Mao Abe’s second single, “I Want to Be Your Girlfriend,” is a love song that portrays a bittersweet unrequited love.
The lyrics tighten your chest as they tell of a summer romance, a secretly held wish that never comes true, and a fleeting end.
It candidly expresses the feelings anyone in love is bound to have, making it painfully relatable.
The melody also captures that indescribable, sentimental mood as summer draws to a close, overlapping with the end of the romance and deepening the sense of poignancy.
left-right confusionYorushika
This is a song by Yorushika that was released digitally in 2022.
Many of you may know it as the theme song for the film Even If This Love Disappears from the World Tonight.
The title term “sayūmō” refers to a state where one can’t distinguish between right and left.
It perfectly captures the protagonist’s painful feelings as their memories with someone important gradually fade, as depicted in the lyrics.
It’s a track that will make anyone who’s seen the film cry, but it’s also a deeply moving, heartrending ballad that I’d recommend even to those who haven’t watched the movie.
That summer is becoming an addiction.Jenīhai
Released in September 2025, this piece is a number that beautifully captures the fleeting nature of summer and the lingering afterimages of memory.
Alongside vivid scenic descriptions, it sings of unforgettable memories being etched ever deeper into the heart over time.
Takashi Niigaki’s crystal-clear piano melodies intertwine with Ikkyu Nakajima’s wistful yet resolute vocals, enveloping the entire track in a nostalgic atmosphere.
It can be described as a work that showcases the band’s ensemble, whose expressive power has grown even further since the album “Jenny Classic.” It’s the perfect song for immersing yourself in cherished memories that resurface at the end of summer.
