What to wear to Rainbow Disco Club: Higashiizu sits at 22°C (72°F) by day and 12°C (54°F) at night in May, on mountain, with a moderate chance of rain. That means a light base with one warm layer you can carry, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans techno, gorp and camping, so black and functional reads as insider.
