Grimm Grimm is the musical project of London-based songwriter, composer and record producer Koichi Yamanoha.

His work is performed in both English and Japanese and has involved collaborations with artists including Lori Goldston, Lætitia Sadier, Le Volume Courbe, Bo Ningen, Josephine Foster, and Klein.

Biography Yamanoha is originally from West Tokyo, Japan, and is the former frontman of the noise-pop group, Screaming Tea Party (2006-2010) in London. The band has released two EPs through Stolen Recordings in the United Kingdom.

In 2014, Yamanoha launched Grimm Grimm with the single, Kazega Fuitara Sayonara / Tell the Truth, through Pickpocket Records, the label founded by Kevin Shields and Charlotte Marionneau in collaboration with Honest Jon's. His debut album, Hazy Eyes Maybe (2015), was released on ATP Recordings. Tracks from the album were used on the soundtrack for the documentary film Uncle Howard (2016) featuring William S. Burroughs and directed and produced by Aaron Brookner and Jim Jarmusch. Grimm Grimm and his ensemble appeared on BBC 6 Music on 19 February 2020 where they were interviewed and performed three songs live in session. The full collection was later issued as a limited edition on tape and vinyl. The mixtape features guest contributions from British musicians Naima Karlsson and Serafina Steer.

In June 2025, video game designer Hideo Kojima announced that several songs by Grimm Grimm would be featured in the PlayStation 5 game Death Stranding 2: On the Beach, the sequel to the critically acclaimed science fiction video game. Developed by Kojima Productions and published by Sony Interactive Entertainment, the game includes a cameo appearance by Yamanoha.

Eternalise, his fourth album, was released in March 2026. The album features guest appearances by Lori Goldston, Paz Maddio, Eiko Ishibashi, Tatsuhisa Yamamoto, Jem Doulton and Josephine Foster, and was mastered by Amir Shoat. Selected tracks from the album were featured in Death Stranding 2: On the Beach.

He has also played at multiple music festivals around the world including Le Guess Who? in Utrecht, Netherlands, Green Man Festival in Wales, Sonic Festival in Belgium, and All Tomorrow's Parties in England.

Musical style The Quietus described the rhythmic composition of Yamanoha's 2020 album, Ginormous, as "Accented with percussion that comes in small clicks and creaks, metronomic rhythms, clacking, cranking sounds like wind-up gears, which sometimes stand in for more conventional drumming, or, as on 'Kyowa Amenohidesu', can create a halting, glitchy tempo." "Throughout his releases, Yamanoha has explored various nuances within his style, blending elements of baroque folk with futurist lyricism, drawing inspiration from English "Infinite canon" forms, where repetitive patterns create an endless, cyclical feel. The melodies often featured at the end of his songs echo like nursery rhymes." Clash reviewed, Hazy Eyes Maybe, describing it as "It might seem a simple, acoustic album, but scrape beneath the surface and there lie intricately crafted layers of mournful, morphing, melancholic hooks".
