With a width of approximately one to two meters, it flows quietly through residential neighborhoods.
Reasons for Selection as One of Japan’s 100 Famous Waters

- Crystal-clear water quality: Clear water sourced from the underground flow of the Mitaki River

- Coexistence with the local community: Continuous preservation efforts by local residents

History of Chishaku Yosui – Water’s Blessing Continuing from the Edo Period
The History of Chishaku Town Plagued by Water Shortage
Chishaku Town in Yokkaichi City has historically suffered from severe water shortages for agricultural use. This region was not blessed with water resources, and farmers constantly struggled to secure water. Chishaku Yosui was developed to solve this challenge.
Origins and Development of the Irrigation Canal
Although there are various theories about the exact time when Chishaku Yosui was developed, written records confirm that it already existed in the early Edo period. Drawing irrigation water from Kaniiike Pond in Kamikamori, the neighboring town of Komono in Mie Prefecture was an extremely challenging project given the technological standards of that era.
Completed through the cooperation and efforts of local farmers, the irrigation canal became a lifeline supporting agriculture in Chishaku Town. From the Edo period through the Showa, Heisei, and Reiwa eras, this waterway has been carefully passed down through generations of local people.
From Irrigation Water to Domestic Water
Although Chishaku Yosui was originally developed as irrigation water for agriculture, due to its clear water quality, it eventually came to be used as domestic water. Records from the Showa era document that local residents actively used this irrigation canal water for cooking and laundry.
The Secret of the Water Source – Kaniiike Pond and the Underground Flow of the Mitaki River
Clear Flow from Kaniiike Pond
The water source of Chishaku Yosui is Kaniiike Pond in Kamikamori, Komono Town. Underground flow from the Mitaki River seeps out of this pond, maintaining stable water volume and crystal-clear water quality throughout the year.
Underground flow refers to water from rivers that seeps underground from the river bottom or banks and flows as groundwater. During this process, natural filtration removes impurities, resulting in extremely clear water.
Characteristics of Water Quality
The water of Chishaku Yosui has the following characteristics typical of underground flow:
- High transparency: Crystal-clear water allowing visibility to the river bottom
- Stable water temperature: Little temperature change throughout the year
- Mineral balance: Appropriate mineral content
- Rich ecosystem: Environment where organisms that prefer clear streams can thrive
This excellent water quality was a major factor in its selection as one of Japan’s 100 Famous Waters.

The fact that koi can thrive in irrigation water so close to residential areas is evidence of extremely high water quality. It is a result of local residents’ daily care of the waterway and their efforts in cleaning and environmental conservation activities.
