Gokayama

Gokayama (五箇山) is an area within the city of Nanto in Toyama Prefecture, Japan. It has been inscribed on the UNESCO World Heritage List due to its traditional gasshō-zukuri houses, alongside nearby Shirakawa-gō in Gifu Prefecture. The survival of this traditional architectural style is attributed to the region's secluded location in the upper reaches of the Shōgawa river. This is also the reason that Gokayama's lifestyle and culture remained very traditional for many years after the majority of the country had modernized. Many of the houses easily surpass 300 years in age.

The Gokayama region includes the former villages of Taira, Kamitaira, and Toga. The gasshō hamlet of Ainokura is located in Taira, while that of Suganuma is in Kamitaira; both are nationally designated Historic Sites.

Ainokura, in the Gokayama region, was inscribed on the World Heritage List in December 1995 as one of the three villages of gassho-style houses.

Ainokura has 20 gassho-style houses. Most of them are 100 to 200 years old, and the oldest is said to have been built some 400 years ago. The gassho roof has a slope of about 60 degrees forming a nearly equilateral triangle. This steep pitch allows snow to slide off the roof easily. The enormous roof is supported by stout, oak beams called "chonabari", which are curved at the base. The roofs are rethatched every 15 to 20 years. Nowadays this is done by Gokayama Forest Owners' Cooperative. More details about the houses.

Akisinonomiya Imperial prince stayed at an Ainokura inn two times. The first time was when he was a Gakushuin in high-school as a second-year student where he took part in a summer training of a geography meeting. While staying in Anikoura he said "I like three places in the world most, one of them is Gokayama". The second time was 9 years after that with his wife.
