There are two open-air museums in Inuyama, Japan that this reminded me of: (1) Meiji Mura, and (2) Little World.
Meiji Mura is an impressive collection of Meiji-era buildings that have been gathered from around Japan, including the lobby of the Tokyo Imperial Hotel (designed by Frank Lloyd Wright) and two full-size churches from Kyoto.
Little World is primarily a collection of traditional houses that have been transported to Japan and reconstructed from around the world.
The amount of effort that went into moving and re-building the dozens of buildings at each site must have been incredible. Both are worth visiting if you are near Nagoya.
