tempest is a recurring club night held at koenji cave, a bar and dj venue in tokyo's koenji neighbourhood, co-presented by the dj and producer hanabi. this is its twentieth edition, continuing a series that has been running monthly or near-monthly since at least early 2024, making it one of the more active ongoing psy club nights at the venue.
the programming spans full-on, psytrance, psy dub, and ambient, with live acts alongside dj sets. koenji cave runs several parallel series out of the same room, and tempest sits alongside nights like phantom, laboratory, and apparition as part of a dense local schedule oriented around psychedelic electronic music.
