Watch the sunlight sparkling on the water as it flows over Kanamenotaki Fall. Keep a lookout for pretty rainbows in the mist.
You're spoiled for sightseeing choice when staying in Hitoyoshi. Kanamenotaki Fall is a great place to start here, but there are loads of other worthy spots to visit. Aoi Aso Shrine, Tengu Bridge, and Hitoyoshi Castle are near the cascade of water and will round out your day nicely.
