A number by flumpool produced in 2011 as the set piece for the NHK All-Japan School Music Competition (Junior High School Division) and also broadcast on “Minna no Uta.” The bond with friends is something invisible to the eye, but the time spent together and the days of crying and laughing side by side surely remain in our hearts.

This work sings about that unseen yet undeniable certainty that we are companions.

It peaked at No.

4 on the Oricon Weekly Singles Chart and was also included on the album “experience.” Not only the fun times, but even the clashes—everything was necessary to deepen the bond.

It’s a song that gently gives a push to friends facing life’s milestones, such as graduation or moving on to the next stage.

This is a song that cheers on everyone who’s worked hard.

Wacci, known for delivering heartwarming tracks that fit into everyday life, released it in July 2018.

It was also included on their album Ultramarine Refrain, released in November of the same year.

In 2019, it was chosen as the support song for Fuji TV’s Mezamashi TV “Japan Connects Project,” gaining attention as it resonated with the struggles and triumphs of athletes.

There are days when things don’t go your way as you devote yourself to club activities or entrance exam prep.

In those moments, this song gently reminds you that the friends who have been striving alongside you can be your support.

It’s a friendship anthem that gives you the strength to keep looking forward, even while carrying frustration.

Give it a listen, and let it take you back to the time you spent with your cherished friends.

This song, which feels like reminiscing about childhood friends, is a collaboration between singer-songwriter Kenshi Yonezu and Masaki Suda, who is active both as an actor and a musician.

It’s included on the album “BOOTLEG,” released in November 2017, and drew major attention, reaching No.

3 on the Billboard Japan Hot 100.

Yonezu sings the first verse, Suda sings the second, and in the latter half you can enjoy their back-and-forth.

Contrasting a gray-tinted everyday life with the innocent days that were once as blue as the sky, it portrays a friendship that remains connected at heart even when apart.

In the music video, the two passing by each other in the same park leaves a striking impression, resulting in a work that blends poignancy with warmth.

It’s a song that gently stays by your side when an old friend suddenly comes to mind.

The song “Hanakotoba,” which entrusts friendship to flowers, is a warm, heartening track.

It was released digitally by Warner Music Japan in July 2025.

With lyrics penned by Neil, the magical words that encourage a downcast friend are truly moving.

The refreshingly cool synths and tight beats also bring out the clarity of the vocals.

It’s perfect for anyone who wants to believe in a friendship that remains unchanged, even when you’re apart.

RPGSEKAI NO OWARI

It’s one of SEKAI NO OWARI’s signature songs, popular across generations and responsible for many hits.

I’ve heard this song was written after the members had a fight.

No matter what kind of argument you have, and even if you get angry, the person you just can’t come to hate is probably a true friend.

The melody is wistful, yet it’s a nostalgic song that everyone has heard before.

It enjoyed a resurgence in popularity after being used as the theme song for the anime “Anohana: The Flower We Saw That Day.” The melancholy melody pairs well with the calm, gentle singing voice.
