Kujira Popular Songs Ranking [2026] (1–10)
spring sunlightKanapu × Kujira1rank/position

It’s a graduation song that blends the gentle warmth of spring sunlight with the bittersweet ache of parting.
Created by virtual singer KAF and producer Kujira, who got his start as a Vocaloid P, it was released as a digital single in March 2022.
Produced as part of KAF’s third-anniversary project “Suite,” the track was written by Kujira specifically for KAF as she actually graduated from high school.
The lyrics avoid direct words like “goodbye,” instead delicately portraying the memories that resurface just before parting and the unspoken tremors of emotion.
With shimmering synths and guitar evoking bright spring sunshine, the song’s arrangement grows more heart-tugging the deeper you listen.
It’s perfect for anyone who wants to look back on memories with classmates before the graduation ceremony.
There’s an intentional openness that allows each listener’s own memories to overlap naturally, revealing something new every time you sing it.

This work gently sings of the importance of embracing loneliness and ordinariness.
Through images of the stillness of a moonless night and scattering light into the darkness, its warm lyrics, which handle a fragile heart with care, resonate deeply.
Kujira centers themes of self-acceptance and growth, beautifully expressing young people’s emotions within a unique worldview.
This piece serves as the theme song for the February 2025 film “My Senpai Is a Boy: Rain, Then Clear,” showcasing the delicate musicality honed on the albums “Until I Can Love Life” and “Vegetable Drawer.” It’s a wonderful song that stays close to the subtle feelings of youth—days at a school festival spent with dear friends, the anxiety and confusion felt while searching for one’s true self.

This song, themed around cherry blossoms shining in the spring night sky, beautifully portrays the beginning and end of love.
The delicate vocals woven by Kujira and Mei-chan, combined with the emotional composition, create an evocative world.
It expresses a love that changes with the seasons through the fleeting symbol of night sakura, and since its release in June 2020, it has captivated many hearts.
The unique sound that fuses electronica and pop harmonizes wonderfully with lyrics brimming with the feel of spring and summer.
It’s especially recommended for the season when you can sense the arrival of spring.
Listening during cherry blossom season will make the lyrical world resonate even more deeply.
It’s a song that offers comfort to those experiencing spring farewells or new encounters.

Kujira is a singer-songwriter also known as a Vocaloid producer.
A male singer renowned for his high notes, he’s gained popularity with sophisticated compositions that draw on his background as a Vocaloid P.
Among his tracks, the one I especially recommend is Wagamama.
This song uses the “Just the Two of Us” progression that’s been showing up incredibly often in recent J-pop, and it features frequent falsetto lines.
It also carries a slightly Black music vibe, so you’ll need a good sense of groove to pull it off.
Give it a try.

This is a song by Kujira that soothes the anxieties you feel when you’ve just moved to the big city.
It captures the complex mix of excitement and loneliness that comes with a new life, conveyed through fresh, vibrant production and a warm vocal.
Released digitally in February 2023, it was also included on the November 2023 album “Yasaishu” (Vegetable Drawer).
Perfect for anyone who feels on the verge of losing themselves amid the bustle of the city.
Kujira’s voice will gently nudge you forward as you strive in a new environment.
A recommended track for everyone opening a new chapter—whether moving, changing jobs, or starting anew.
Osmanthus feat. Adokujira6rank/position

Triggered by the scents of autumn, this song tells a bittersweet story that recalls parting with someone dear.
Created by Kujira—also known as a Vocaloid producer—and featuring singer Ado, it delicately traces the protagonist’s helpless emotions as they struggle to regain peace, set against an urban, chill electronic sound.
Ado’s voice, blending hardness and clarity, sharpens that cool, lingering pain.
Released in December 2019, the track was later included on the album “Nerenai Yoru ni Curtain wo Akete” (“Open the Curtain on Sleepless Nights”).
It was also added to a popular rhythm game, and continues to be widely listened to.
It’s perfect for those long autumn nights when you want to sink into a slightly sentimental mood.

This song weaves together Kujira’s production and yama’s translucent vocals in perfect harmony, creating a melancholic soundscape.
Delicately portraying the solitude of a world fallen asleep, it was included on the album “Nerenai Yoru ni Curtain wo Akete,” released in October 2020.
Wrapped in sadness and poignancy yet suffused with a gentle warmth, its tones offer quiet comfort.
In April 2024, a live performance video celebrating the 5th anniversary of yama’s activities was released, captivating fans.
For nights spent alone, moments when the heart feels heavy, or when thinking of someone—this is a song that stays close during those quiet times, becoming a source of support for many listeners.
