Gassho-style is one of the traditional architectural styles for houses in Japan.
In most of the cases, the houses have a steep roof with an angle from 45 to 60 degrees.
It is said that in a region with heavy snowfall, this slope helps to mitigate work for snow removal and, in the case of a region with heavy rains, it helps the drainage of rainwater.
In the remaining gable roofed houses
it is said that there is a lot of working space in the attic.
The reason for the steep angle is to secure a two-layers or three-layers space which is just the right space for families raising and selling silkworms.
Shirakawa-go is village famous for its gassho zukuri style houses, and in 1995, together with Gokoyama, was registered as World Cultural Heritage Site by UNESCO.

Shirakawa-go has also a very beautiful landscape.
It is often lit up in winter and it is famous as a tourist destination

Gassho zukuri is a style of architecture that concentrates the wisdom of a region affected by heavy snowfall and dedicated to sericulture.

The interior of the gassho zukuri constitutes the third floor.
The attic has been used as a work space.

Work to re-cover the roof of thatch is carried out once in 20 to 30 years, with maintenance work carried out twice a year.These tasks are carried out in cooperation with other local residents, and this system of cooperation is called “Yui”
