51st Noboribetsu Hell Festival (51st Noboribetsu Jigoku Matsuri)
Date: August 30 (Sat)-31 (Sun), 2014
This is a cheerful event in which the door to “Hell” of Jigokudani, a famous place in Noboribetsu Onsen meaning “hell valley,” opens once a year and Yama (the King of Hell), a red ogre and a blue ogre come to the town. Yama (King of Hell)-shaped floats and huge ogre-shaped portable shrines parade around the town as ogres dance in groups and local forms of folk entertainment are performed for the crowds.
