Echigo-Matsunoyama Museum of Natural Science “Kyororo”

What is KYORORO?

“Kyororo” is a natural science museum in Matsunoyama Tokamachi, Niigata. The name of our museum derives from the song of the ruddy kingfisher, a bright red bird who migrates from warmer islands in Southeast Asia to our beech forests in early summer for reproduction.

A Huge Rusty...Submarine?

With a structure 160 m long situated in an rural forest, the Echigo-Matsunoyama Museum of Natural Science “KYORORO” is quite inconspicuous. It was designed by architects, Takaharu and Yui Tezuka, and constructed from plates of weathering steel that weigh approximately 2,000 t. The building appears red due to rusting, and this outer layer of rust actually protects the inside of the building by acting as a guard against further rusting!
