Music Cafe Bar One's

Music Cafe Bar One's was a DJ bar in Ikebukuro, Tokyo, at 2-2-6 Ikebukuro, Toshima-ku. It opened in December 2017 on the fourth floor of Palace Ikebukuro, operating as both a bar and a club before closing at the end of April 2026. Operations paused temporarily in 2020 during the COVID-19 pandemic. The venue held three to four DJ events each week.

The venue held about 80 people, with fewer than 30 seats. Its sound system used speakers facing in four directions and two subwoofers. Parties focused on house and techno, with recurring nights including WARMTH and the house and deep-house party Guidance, which began there in 2022. Promoter Rikk ran events at the venue; artists who played there included OPTIMIST, Ginji, HALU(Tribal Connection) and RED-S. Guidance held its final edition at Music Cafe Bar One's on April 12, 2026. During its first two years, the venue hosted more than 200 artists from Japan and abroad, with around 20 overseas DJs a year.
