Mori Shogunzuka Kofun

Chikuma City, Nagano Prefecture

The best distinction of the Mori Shogunzuka Kofun museum is their amazing reproduction of the kofun's burial chamber, as seen here. Cultural heritage sites all over the world - from the Americas to Egypt, Neolithic France to China - are in terrible danger from tourism and overdevelopment, and so good reproductions like this are the wave of the future.
