a three-day outdoor camping rave held at a dedicated outdoor event site in the mountains of yamanashi prefecture, roughly two and a half hours from tokyo by car. the event is built around a programmatic pairing of goa trance and suomi trance, drawing live acts and djs from finland and across europe alongside local performers. a pre-party club night in tokyo serves as a warmup event in the months before.

the site includes free first-come camping, bungalow accommodation, vendor stalls, and shuttle bus access from central tokyo. the format runs from friday afternoon through sunday midday, with music stopping late sunday morning.
