The thatched roof houses known as "Gassho-zukuri" are unique to this area,
This is a very rare style of house that still exists only in Gokayama and Shirakawa-go.
The Ainokura Gassho-style Village, registered as a World Heritage Site, has 23 buildings.
There are nine gassho-style houses remaining in the Suganuma Gassho-style Village.
Many of them are about 100 to 200 years old, and the oldest ones are said to have been built 400 years ago.
It is a sturdy structure that can withstand the harsh natural environment of deep snow, and is a rational building that combines a place for living and work.
Gassho-zukuri is a great invention born from people's wisdom for living.
Ainokura and Suganuma are a nationally designated historic site and a cultural property protection area registered as a World Heritage Site.
