Yuya no Shimizu is a clear natural spring located in Sazawa, Chonan Town, Chiba Prefecture. In 1985, it was selected as one of Japan’s 100 Remarkable Waters, a list recognizing notable water sources throughout the country.
The spring has long been valued by the local community and continues to be used as a source of agricultural water. Surrounded by lush greenery and historic religious sites, Yuya no Shimizu is a peaceful destination where visitors can experience the connection between nature, local life, and traditional Japanese beliefs.
Yuya no Shimizu is also known as the “Sacred Spring of Kobo Daishi.” According to local tradition, Kobo Daishi (Kukai), the famous Buddhist monk who founded the Shingon school of Buddhism, visited this area while traveling to spread Buddhist teachings.
At the time, local farmers were suffering from a severe drought. According to the legend, Kobo Daishi used his spiritual powers to cause pure water to spring from the ground, providing relief to the people.
This story has been passed down through generations, giving the spring a strong connection with Kobo Daishi and the area’s religious heritage.
During the Muromachi period (1336–1573), the spring came under the administration of Tsurugaoka Hachimangu Shrine and developed as a bathing and recuperation site operated by the shrine.
At the time, the area was known as Yuya, a name associated with the bathing facilities. This history is believed to be connected to the alternative name “Yuya no Shimizu,” which is still associated with the spring today.
Yuya no Shimizu produces approximately 48 liters of water per minute, with a relatively stable flow. The water continues to be used for agricultural purposes in the surrounding area.
Visitors should note that the spring water must be boiled before drinking. Although the spring is famous for its clean and refreshing appearance, it is important to follow local guidance concerning its use.
