Clear water counted as one of Japan’s 100 Fine Water gushes out at the base of a 500-year-old huge cedar tree in the precinct of Hakoshima Fudoson Temple in Hakoshima, Higashi-Agatsuma-cho, Agatsuma-gun, Gunma Prefecture. It springs out 30,000 tons of water per day. The water is supposed to be the sub-soil water of Lake Haruna.

Legend has it that the wife of a Warring States period warrior of the Kibe clan was pursued by the enemy and finally threw herself into Lake Haruna. Knowing this tragedy, her son Priest Enko of the nearby temple sent her memorial tablet to the bottom of the lake to appease her soul. The tablet, however, floated out of water in the springs later. This memorial tablet is placed in the temple hall even today.

The spring water pours into the Narusawa River, which supplies water for agriculture, trout aquaculture and the prefecture’s Inland Water Fisheries Experiment Station as well as the drinking water to the local village. This clear water is so cold that your hand will become numb.
