Vejret i Nozawa Onsen (Nozawa) i maj

Forum regulars call May one of the best weather months to visit Japan generally, and Nagano Prefecture's higher-elevation spots like Karuizawa run noticeably cooler than Tokyo - low 20sC by day even in early May. Conditions vary sharply with elevation though: up in the mountains around Kamikochi, snow can still linger into early May before the valley turns lush green by month's end, with snowy peaks visible in the distance even in the warmer weeks. One caveat for wildlife-focused visitors: snow itself is unlikely in May at the Snow Monkey Park, but the monkeys' appearances are unpredictable regardless of season, with no guaranteed viewing time.
