Karuizawa in late September was at a calm, peaceful, and comfortable time after the din of summer. Sezon Museum of Modern Art sits in a forest, and was actually designed as a “Museum in deep green.” We pedaled our bicycles up a gentle slope in the woody area heading north for 30 minutes from Naka-Karuizawa, and finally reached the gate of this museum. After passing the gate, we walked through a beautiful forest. It was nice and refreshing. The murmur of a small stream in the museum garden, and the sound from the leaves rustling in the wind, were comfortable to our ears. The temperature was lower than 10 degree centigrade in the morning and the autumn leaves had just started to turn. We had a pleasant time sitting at the open-air terrace of the museum café.
