The Shirakawa-go And Neighboring Gokayama Regions Line The Shogawa River Valley In The Remote Mountains That Span From Gifu To Toyama Prefectures. Declared A UNESCO World Heritage Site In 1995, They Are Famous For Their Traditional Gassho-zukuri Farmhouses, Some Of Which Are More Than 250 Years Old. Gassho-zukuri Means Constructed Like Hands In Prayer, As The Farmhouses' Steep Thatched Roofs Resemble The Hands Of Buddhist Monks Pressed Together In Prayer. The Architectural Style Developed Over Many Generations And Is Designed To Withstand The Large Amounts Of Heavy Snow That Falls In The Region During Winter. The Roofs, Made Without Nails, Provided A Large Attic Space Used For Cultivating Silkworms. Photo
