Insider tip — Bell Sakura no Yu serves Utsunomiya, the gyoza capital of Japan where the pan-fried dumpling arrived with soldiers returning from Manchuria after World War II and became embedded in local identity to the point where the city consumes more gyoza per household than anywhere in Japan. The Oya Stone Museum underground cathedral, carved from the soft volcanic tuff quarried beneath the city, is one of Tochigi most extraordinary hidden spaces.
