Dosojin Nozawa Onsen Fire Festival

The Nozawa Onsen Fire Festival (Dosojin Matsuri) is one of Japan’s most significant fire rituals, held annually on January 15 in the hot spring village of Nozawa Onsen, Nagano. Recognized as a National Important Intangible Folk Cultural Property, the festival centers on a dramatic battle to defend a seven-meter-tall wooden shrine (shaden). The ritual is performed by village men who are in their “unlucky ages” (yakudoshi)—specifically 25 and 42 years old. The 25-year-olds defend the base of the structure, while the 42-year-olds sit atop it, as other villagers launch a coordinated assault with flaming torches to set the shrine ablaze.

The festival is the culmination of months of preparation, beginning in October when sacred trees are harvested from the local mountains. The construction of the shaden is a feat of traditional joinery, completed without nails just days before the event. Following a purification ceremony for the Dosojin—a deity believed to protect travelers and ensure healthy children—the fire battle commences around 8:30 PM. The conflict is a stylized enactment of purification, ending with the entire structure being consumed by fire to ensure good fortune for the coming year.

For visitors, the event is a high-intensity sensory experience, but it requires careful preparation for sub-zero temperatures and icy conditions. High-traction winter boots are essential, and spectators should wear clothing that they do not mind getting marked by falling ash or embers. While local residents frequently distribute free sake as part of the celebration, visitors are encouraged to drink responsibly and stay well behind the designated safety ropes, as the heat and fire can be unpredictable. Given the festival’s popularity, arriving at the site by 6:00 PM is recommended to secure a vantage point, and booking accommodation in the village months in advance is mandatory.
