Kobukuro Popular Song Ranking [2026] (31–40)
Summer rainKobukuro31rank/position
This is a song by Kobukuro that was used as the opening theme for the TV Tokyo anime Cross Game.
You can almost picture two people huddling under a single umbrella, illuminated by summer lightning.
The piece portrays a bittersweet emotional sway between the rain that tries to wash away memories of a past love and the vivid, summer-dream-like memories that remain nonetheless.
It was released in April 2009 as the B-side to the single Niji (Rainbow) and is also included on the album CALLING.
It’s a captivating work that lets you savor both the exhilaration of summer days and a sudden, nostalgic loneliness at the same time.
TwilightKobukuro32rank/position
Twilight is a song that straightforwardly expresses feelings for someone who has grown distant.
It’s a track released by Kobukuro in 2015 and was used as the theme song for the film Twilight Sasara Saya, starring Yui Aragaki.
Parts of a person that can only be seen from the closeness of being a couple, and memories that can no longer be made, weigh down as sorrow after a breakup.
Until you can overcome it, it may be nothing but a burden, but with time, you will surely come to realize how irreplaceable those things are.
SunKobukuro33rank/position
The upbeat, refreshing summer song “Taiyo” (The Sun) was released in 2002 as a double A-side single together with “Negai no Uta” (Song of Wishes).
While the overall tempo is on the faster side, the spacing between words—except in the A verse—is relaxed enough that you won’t feel rushed singing it.
The rhythmic section in the A verse is built on similar melodic patterns, so once you get the hang of it, it becomes easy to sing.
Riding the groove and having fun is the key to performing this song well.
Give it a try not only at karaoke but also in the car or during leisure activities—it’s great for all kinds of situations.
Treasure IslandKobukuro34rank/position
Among Kobukuro’s early songs, “Takarajima” (Treasure Island) enjoys enduring popularity with fans.
It evokes the purity of childhood, when everything looked beautiful and, together, they discovered their very own “treasure island.” As they gradually grow up, graduate, and set off on separate paths, the song encourages taking that first step toward the “treasure island” that surely lies ahead on each of their journeys.
Graduating from familiar places and leaping into new environments—taking on new challenges—takes courage, and this is the song that gives you a gentle push when you need it.
paper airplaneKobukuro35rank/position
Kobukuro is a pop duo that enjoys strong support for their orthodox pop style.
They’ve produced numerous classics, but among their songs, Paper Airplane isn’t particularly well-known.
That said, its extremely catchy melody has earned it enduring support from many fans.
The way they write lyrics that resonate with so many people is quintessential Kobukuro.
Be sure to check it out!
Wings of the HeartKobukuro36rank/position
Kokoro no Hane is a song included on Kobukuro’s best-of album ALL SINGLES BEST 2, released in 2012.
It originally dates back to their days as street musicians and has long been a fan favorite.
Looking up at the sky that connects us, he thinks of his girlfriend in a distant town…
It’s lovely not only to let his longing grow, but to make up his mind to actually go and see her.
Goodbye, HEROKobukuro37rank/position
Kobukuro is a musical duo that heals listeners’ hearts with dramatic ballads.
They’re known for powerful message songs delivered with assured vocal prowess.
While they often create songs with a warm atmosphere, “Sayonara HERO” is a powerful, passionate rock tune.
It’s included on their 2009 album “CALLING” and was created for the musician Kiyoshiro Imawano.
The track is filled with emotional feelings for a hero they once admired.
It’s also recommended to listen while thinking of someone you looked up to in your childhood.
Star SongKobukuro38rank/position
A track by Kobukuro included on their album “Star Made,” released on August 4, 2021.
As the title suggests, it’s a gentle song that evokes a quiet summer night sky, and musically it’s very much in their style—easy to hum and approachable.
If you focus on singing carefully throughout, it shouldn’t be too hard to score high at karaoke.
That said, the high notes in the chorus might be a bit tough for the average male singer, so it might be a good idea to check the key settings in advance.
heartKobukuro39rank/position
The song “Kokoro” (“Heart”) is a number that gives you an opportunity to face your own heart.
Released in 2017, it was chosen as the theme song for the film “I’m Taking a Break at Work Now” (Chotto Ima Kara Shigoto Yamete Kuru), and the music video features NAOTO from EXILE and Sandaime J SOUL BROTHERS from EXILE TRIBE.
The track unfolds at a relaxed pace, as if having a gentle conversation with your heart, making it easy to sing without rushing.
If the key feels a bit high, try lowering it a few steps so you can sing more comfortably and freely.
The Way Back to the FutureKobukuro40rank/position
Released by Kobukuro in September 2006 and included on their classic album ALL SINGLES BEST—which became a massive hit with total sales exceeding 3.5 million copies—this song was also used as the image song for NTT West’s telegram service.
The lyrics, which open with a melancholic autumn scene, poignantly portray the regret of not being able to be honest and the earnest wish to face each other once more, tightening the chest.
With its warm, acoustic sound and the duo’s powerful vocals gently nestling close to the heart, it is a gem of a ballad perfect for listening to deeply on long autumn nights.
