The Nasu Mountain Opening Festival is an annual event that celebrates the start of the climbing season of the Nasu Mountain Range. Held at the Nasu-Take Shrine, this festival is primarily conducted to pray for the safety of climbers, with the local Nasu Onsen Shrine priest officiating the ceremony. On the day of the event, participants can enjoy the magnificent view from the summit of Chausu Mountain and embark on a mountain tour around nearby peaks like Minatsuki Mountain after the ceremony. It’s a wonderful opportunity to appreciate the natural beauty of the Nasu Mountain Range and the season of fresh greenery. By participating in this event, you can gain a rare climbing experience and a valuable chance to engage with local culture. It will be a special day to feel the local customs and nature. In May, when hydrangeas are in full bloom in Nasu, enjoy a once-in-a-lifetime mountain experience. Visit the Nasu Mountain Opening Festival to fully indulge in the grandeur of nature and local traditions.
