CAVE
Open since 2009, Cave is a small, intimate underground DJ bar in Koenji, specializing in psychedelic trance (Psy-Trance / Goa) alongside techno. It's often described as the only club of its kind in Japan devoted to psytrance, and a long-standing cornerstone of that community.
The psychedelic-themed space typically runs a bar/DJ room and a small main floor for dancing, open Fridays, Saturdays and holidays from late. Come for a dedicated, tight-knit scene rather than a mainstream night out.
