Historic Villages of Shirakawa-go and Gokayama

This time, I will introduce about Historic Villages of Shirakawa-go and Gokayama. In 1995, Historic Villages of Shirakawa-go and Gokayama registered on UNESCO's World Heritage list. They represent architectural form that represent important era, and they are in the threat to damages. Therefore they registered on UNESCO's World Heritage list. They stand in Gifu and Toyama. Their character is their roof which are large area and have sharp angle, because they are in heavy snowed region and people want to remove the snow from the roof easily. A lot of tourists have visited there since they registered on, and this area receive benefit. However, visitor's manner become big problem nowadays. For example, they throw away garbage everywhere, and they open doors of house and resident's privacy are invaded. I would like to go to there someday, but I should have good manners then.
