The Idojiri Archaeological Museum sits at the southern foot of Mt. Yatsugatake. Looking south, visitors to the museum can see beautiful Mt. Fuji, and rising up in front of them are the towering heights of the Southern Alps' Mt. Kai-Komagatake and the three peaks of Mt. Hoo. The museum has conducted its own research into areas such as the theory of Jomon agriculture and Jomon iconology, and those materials, together with its exhibition of pottery of various shapes and sizes, make this museum well worth a visit.
