Nozawa Onsen Dosojin Matsuri 野沢温泉の道祖神祭り
On 15 January those not in their unlucky year attack with fire, and those who are in it defend.
A festival of the god of roads (dōsojin), protector of the village boundaries and of children's growth, which in Nozawa Onsen takes the form of a real ritual siege by fire. Handed down since at least the Tenpō period (1830–1844), it has been an Important Intangible Folk Cultural Property since 13 December 1993, and is one of the three greatest fire festivals in Japan.
