Held in Matsunoyama Onsen, the festival combines local customs, humor, and celebration, reflecting Japan’s unique blend of cultural heritage and community spirit. The event often includes other local rituals, adding depth and context to the experience.
The Tokamachi Son-in-Law Throwing Event 2026 will take place on January 15, 2026, at Yakushidou Temple in Matsunoyama Onsen. New grooms are paraded around the venue before being thrown from a 5-meter-high cliff into a snow-covered area, which safely cushions their fall.
The ceremony is a mix of fun and tradition. Participants are encouraged to enjoy a drink of local sake beforehand, adding to the festive atmosphere. Alongside the throwing event, visitors can witness Suminuri (Ash Smearing), another local ritual performed in Matsunoyama Onsen town later in the day.
This unusual but captivating festival is ideal for travelers seeking authentic, offbeat experiences in Japan’s winter season.
