After China, Japan has more UNESCO World Heritage Sites than any other country in East Asia. The country has 19 in total and the historic village of Gokayama is one of them. The site comprises both Gokayama village and Shirakawa-gō village (also in this list), and it's located in the Shogawa river valley. The villages are famous for their traditional "Gassho-zukuri" style of houses, which means "constructed like hands in prayer". Some of them are more than 250 years old.
