It is known as one of Japan’s representative spring water spots. Crystal-clear water gushes forth from a small flat area nestled in the mountains, and it is a rare location throughout Japan where you can directly observe the beginning of the first-class river, the Himekawa.
This article provides a thorough explanation of information you should know before visiting, from the charm of Himekawa Spring Source Water to detailed access methods, highlights for each season, and surrounding tourist information.
What is Himekawa Spring Source Water | Crystal-Clear Stream Selected as One of Japan’s 100 Famous Waters
Himekawa Spring Source Water is a spring located in the Oyomi district of Hakuba Village, characterized by clear water gushing forth from a mountain valley at an elevation of approximately 750 meters. With this spring as its source, the Himekawa River begins and flows from Nagano Prefecture through Niigata Prefecture to the Sea of Japan.
Characteristics of Himekawa Spring Source Water
The reason Himekawa Spring Source Water was selected as one of Japan’s 100 Famous Waters lies in its high water quality and the richness of the surrounding natural environment. The water temperature of the spring remains stable at approximately 11 degrees Celsius year-round, and it boasts exceptional transparency, allowing you to see to the bottom of the water.
Water gushing forth from between the sediment layers of the Oyomi Wetland on the south side of Doukaku Mountain, the source of the water source, forms a pure spring water without river inflow. To protect this precious natural environment, the Himekawa Spring Source and the surrounding Oyomi Wetland area was designated as the “Himekawa Spring Source Prefectural Natural Environment Conservation Area” based on Nagano Prefecture’s Natural Environment Conservation Ordinance on March 31, 1980, and was further designated as the first recipient of the “Natural Scenic Exploration Garden” system in 1978.
The Central Divide Between the Shinano River System and the Sea of Japan
A notable geographical feature of Himekawa Spring Source Water is that it is separated by a watershed from Aoki Lake, which belongs to the Shinano River system. Within just a few kilometers, the continental divide is located where water flows in one direction toward the Pacific Ocean side (Shinano River system) and in the other direction toward the Sea of Japan side (Himekawa).
A location with a first-class river source and continental divide near a national highway like this is rare throughout Japan and is known as a geographically valuable place. Because you can directly observe the beginning of a river in a flat area, it also has high educational value and is used in school nature observation field trips.
