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.

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 highly addictive Vocaloid track that opens with stylish guitar cutting.
It’s a song by the Vocaloid producer Kujira, also known as the composer of “Haru wo Tsugeru,” his collaborative track with singer yama, and it was released in 2020.
The lyrics overlay the image of falling nighttime cherry blossoms with the feelings at the moment of parting, tightening the chest, yet perhaps thanks to the brisk tempo, it creates a unique world that doesn’t end in mere sadness.
Many listeners will relate to the almost philosophical feeling of “it goes on until the end of the end.”
