Sean's Japan Travel Journal: Yokote Kamakura Festival. A 400 year old tradition where kamakura both big and small are built at various locations across the city center. Kamakura are igloo-like bell-shaped houses made of snow with alters dedicated to the water deity. Inside a kamakura there is usually a charcoal brazier set up to provide warmth and grill rice cakes for visitors paying respect to the deity. At dusk, the kamakura are illuminated.
