Only famous artists! Anime songs that energize the Reiwa era
When it comes to anime songs, in the Showa era there were many child-oriented tracks made specifically for each anime, while in the Heisei era there were many tie-in songs that often had little to do with the anime’s storyline.
In contrast, these days there are more and more songs written for anime that have also become signature hits for the artists themselves.
This may well be because Japanese anime has gained popularity overseas.

Protect the LightNEW!Spitz
Released in October 2025 as a digital single—the first in about two and a half years—it serves as the opening theme for the TV anime SPY×FAMILY Season 3.
Masamune Kusano commented, “While it’s a work whose comical and cute depictions are fun, I wanted the song to face the sorrow that flows at the root of the story rather than run from it,” and true to his words, the sound beautifully captures a world where poignancy and hope intersect.
The rich arrangement, co-produced with Seiji Kameda, is also a highlight, with horn sections and organ adding vivid color.
It gently gives a push to the courage to protect what matters most.
Adult Chick ChildrenNEW!yama
A high-velocity arrangement that grabs your ears—the opening theme for the TV anime “SANDA.” yama’s razor-sharp vocals confront the universal question: What does it mean to become an adult? Simply growing older doesn’t make you one, but having youth doesn’t make you a child either.
The song vividly captures the struggle with change and the pains of growth.
It will be available digitally in October 2025, with a CD release in December.
Don’t miss the chance to experience yama’s undeniable coolness!
