Nakamura Hak, born in the Ōta district of Tokyo, was a Japanese office worker turned singer‑songwriter whose moniker reflected a minimalist aesthetic; all of her recordings were captured in a single take without digital editing, showcasing her simultaneous vocal and acoustic guitar performance. In spring 2026, despite her then‑unknown status, she was chosen to perform the closing themes for the Witch Hat Atelier anime adaptation and the opening for the TV Tokyo drama Lunacy, propelling her into public awareness. That same month she signed with Avex Group’s maximum10 imprint and released her debut EP Shiro wa Yume on 20 May 2026, a physical CD that omitted digital distribution; the title track peaked at number eight on Billboard Japan’s Plantech radio chart for the week of 11–17 May. The limited edition offered a ticket to her inaugural free national tour, Unplugged (Out‑store) Live Tour – Itan. On 10 June 2026, she issued her first single in physical format, "Tada Utsukushii Noroi" which three tracks that served as Witch Hat Atelier themes. Her distinctive “unplugged” approach attracted critical attention from outlets such as Music Natalie, with reviewers noting the raw human presence captured in her performances.
