The name 'Uriwari' derives from the historical practice of 'uri-wari,' meaning 'to split melons,' referring to the local custom of chilling melons in the cold spring water.
The water's constant year-round temperature of 12.6 degrees Celsius remains stable regardless of seasonal surface air fluctuations.
The waterfall is fed by a spring surfacing from the mountainside rather than a traditional river-fed cascade.
The site is officially recognized by the Japanese Ministry of the Environment as part of the 'Heisei Meisui Hyakusen' (100 Remarkable Waters of the Heisei Period).
Uriwari Falls is a cascading, spring-fed waterfall located in the mountains of Wakasa, Fukui Prefecture. The water source originates from a limestone layer in the adjacent forest, maintaining a constant temperature of approximately 12.6 degrees Celsius throughout the year. The site is designated as one of Japan's 100 Remarkable Waters by the Ministry of the Environment. The water flows over moss-covered rocks, creating a distinctively cool, humid microclimate that fosters a lush bryophyte environment. Historically, the cold spring water was utilized to chill local produce, specifically watermelons and vegetables, due to its low and consistent temperature. The falls are located within the Wakasa-wan Quasi-National Park area.

Bring a towel to dry your hands, as the water is exceptionally cold and refreshing.
Wear shoes with good grip, as the moss-covered rocks and forest paths can be slippery.
Bring a reusable water bottle to sample the spring water directly from the source.
Do not attempt to climb the waterfall rocks, as they are fragile and hazardous; do not expect a large, thunderous cascade, as this is a quiet, gentle spring-fed flow.
Stay on marked trails to protect the delicate moss and surrounding forest ecosystem; do not use soaps or detergents in the water.
