Watch the sunlight bouncing off the water as it tumbles over Daisen Falls. Keep a lookout for any rainbows in the mist.
You're spoiled for sightseeing choice when spending time in Kotoura. Daisen Falls is an ideal place to kick off here, but there are plenty of other interesting attractions to experience. Daisen-Oki National Park, Daisenji Temple, and Okudaisen Ski Area are not far from the cascade of water and will fill in your day nicely.
