aiko Popular Songs Ranking [2026] (11–20)

A winter love story spun by aiko.
This song portrays a delicate, fleeting form of love.
Released in February 2009, it became her first single to reach No.
1 on the Oricon Weekly Singles Chart.
It was also used in a Bridgestone bicycle “Albelt” commercial.
A relationship that’s distant yet close, a one-night connection, the frustration of unrequited love—these complex emotions resonate with aiko’s delicate vocals.
It’s a song you’ll want to listen to on a quiet winter night while thinking of someone.
It’s sure to gently embrace the heart of a woman troubled by love.
around two o’clockaiko16rank/position

Singer-songwriter aiko has created numerous masterpieces themed around heartbreak.
Among them, a B-side track from her second single, “Around Two O’Clock,” continues to enjoy unwavering support from fans.
The song depicts a woman calling her unrequited love at two in the morning.
That alone is heartrending, but if you listen closely, you realize it also conveys the sorrow of her noticing that the man is with a woman she doesn’t know.
The emptiness is almost overwhelming, and it’s enough to bring tears to your eyes.

It’s a warm song that depicts an ordinary breakfast with a loved one.
The wish for the other person’s happiness is expressed through a unique perspective—the color of the straw placed in the breakfast drink—showcasing aiko’s characteristically delicate sensibility.
While honestly portraying the anxieties and conflicts that grow as the relationship deepens, it still conveys unwavering love through a refreshing melody.
Released in May 2018, the track was chosen as the theme song for TBS’s information/variety program “King’s Brunch” and was also included on the album “Wet Sandal Summer Beginnings” released the same year.
It’s a recommended listen not only for those who share breakfast with someone special, but also for anyone who dreams of such moments.
Capsuleaiko18rank/position

Compared to aiko’s other songs, “Capsule” is characterized by a melody that doesn’t move much, making it a song where you can follow the tune straightforwardly.
It seems that aiko herself has commented to that effect.
As you listen, the sections sung softly in head voice at the beginning gradually shift to an emotional chest voice toward the latter half.
In the first half, it might be good to relax and sing gently and lightly.
Also, the very end of this song features a long sustained note.
It’s the moment when the emotion is at its peak, so it’s a part I’d love for you to sing comfortably in chest voice.
The sustained vowel is “o.” Since “o” makes it easy to open the throat and pronounce, there shouldn’t be any problem as long as you take a good breath and prepare before you start singing.
Send the breath flying far into the distance!
blue skyaiko19rank/position

This is a bittersweet yet warm medium-tempo ballad that paints a sky whose appearance changes with the cloudiness of one’s heart.
The title may suggest a refreshing image, but in reality it delicately conveys inner wavering.
Released in February 2020 as the 39th single and also known as a song from a Mercari commercial, it was included on the album “Doushitatte Tsutaerarenai Kara” (“Because No Matter What, I Can’t Convey It”).
It will gently stay by the side of those who, in fleeting moments when they look up at the sky, feel loneliness, or who carry the pain of parting while going about their days.
Why not listen to this masterpiece that’s perfect for spring’s melancholy?

Singer-songwriter aiko continues to portray the delicate nuances of love with razor-sharp lyrics and a one-of-a-kind melody.
This song conveys a bittersweet yet resolute vow to never wear again a piece of clothing bound to a special memory.
The unforgettable recollections hidden beneath its sound may gently touch the drawers of the heart that each listener carries.
It’s one of the tracks on her 16th major-label album, “Zanshin Zansho,” and also serves as the opening theme for the TV anime “Apocalypse Hotel.” A bitter yet beautiful pop number.

tomorrowaiko21rank/position

The major-label debut single by singer-songwriter aiko, who has released numerous classics featuring poignant lyrics that resonate with women and cool, jazz-tinged chord progressions.
Used as the theme song for the film “Shinsei Toire no Hanako-san” (New Toilet no Hanako-san), it is, in fact, the only song in aiko’s catalog that she did not compose herself.
Its sprightly beat and digital sound offer a different charm and impression from the aiko you might imagine.
The contrast between the dark arrangement and her cute vocals is addictively appealing—an uplifting dance tune that gets your energy up.
