Agano (along the Seibu Chichibu line) has a jazz festival sometime mid November when the maples in the Togo Koen (Togo Park) are in their full blazing red glory. The jazz festival is at night and in the open air (so dress warmly). The steps leading to the band stand is lighted with candles. It is one of our favorite yearly events to go to. The Seibu Line has posters about this event weeks before so watch out for it.
