Every winter, Kinugawa Onsen turns into a celebration of good fortune and fun with the Kinugawa Onsen Oni Festival. Running from late January through late February, this unique event blends the traditional Setsubun custom of driving away evil with Kinugawa's own "oni" (demon) heritage. The result is a colorful, family-friendly festival where humans and demons join forces to welcome luck and happiness for the year ahead.
The festival's theme, "Demons of the World Gather in Kinugawa," sets the stage for an imaginative mix of folklore and festivity. One of its most popular attractions is the SL Shōfuku Oni Train, a steam locomotive that carries costumed demons and local mascot characters on a ride through the scenic area. Alongside the train experience, visitors can enjoy taiko drumming performances, wood-carving shows, and a variety of demon-themed foods.

With cultural workshops and stamp rally games adding to the fun, the Kinugawa Onsen Oni Festival offers a unique twist on Setsubun traditions. It's an event where families can laugh with "oni," celebrate renewal, and experience the warm spirit of Kinugawa Onsen in the heart of winter.
