This is already turning into a trip of contrasts. Tokyo was all rush and all people, all the time. Mount Fuji (or at least Lake Kawaguchiko) was quiet, with very few people and little noise except the occasional clank from the bike chain. Matsumoto, a city near the Japanese Alps, strikes a balance somewhere between the two.
The main feature, right in the centre of the city, is Matsumoto Castle. It’s one of the oldest and best preserved castles in Japan.
