The way the water falls straight down the cliff of Mt. Honzan like white threads gives this waterfall its name (“shiraito” means “white thread”), which was already in use by the beginning of the Edo Period. Although it can’t be seen from land, you can get a good view of the waterfall from a sightseeing boat. Oga Peninsula’s natural wonders are protected as part of Oga Quasi-National Park and are an important resource for tourism. 8,156ha, or about 1/3 of the region, was designated a protected area in 1973.
