Hakushi Hasegawa, born December 21, 1998, in Tokyo, Japan, is a Japanese singer-songwriter known for their work in electronic music. Hasegawa began taking piano lessons at a young age and later became involved in online communities discussing electronic music, which introduced them to influential artists like Nyolfen. Their breakthrough came with the release of “Hadairo No Kawa” on SoundCloud in 2016, which went viral in Japan and caught the attention of Maltine Records founder Tomohiro Konuta. This led to their debut EP iPhone Six Plus in 2017. In 2018, Hasegawa released their follow-up EP Somoku Hodo under Musicmine, and in 2019 they debuted their first full-length album Air Ni Ni, which received critical acclaim. In May 2020, Hasegawa released Bones of Dreams Attacked!, an album featuring stripped-back cover versions of J-pop and J-rock songs. They performed at the Secret Sky Festival in response to COVID-19 restrictions on live music. In July 2023, Hasegawa signed with Brainfeeder, the label founded by Flying Lotus, becoming the first Japanese act to do so. Their subsequent releases include “Boy’s Texture” and “Departed”, both accompanied by animated music videos. On July 24, 2024, they released their third album Mahōgakkō, which was described as more chaotic and disorganized than their earlier work.
