Visitors can also test their skills in target games, try their hand at sword fighting demos, or enjoy Japanese street food from colorful yatai stalls.
The festival’s grand finale features a powerful taiko drum performance, which echoes through the valley and brings the community together in one last summer celebration. With easy access from most accommodations in the Hirafu area, it’s a must-attend event for anyone visiting in late August.
