What is Taro-bo Shimizu (Ippai Shimizu)?
Taro-bo Shimizu is a collective term for spring waters existing in multiple regions. Also known by the name “Ippai Shimizu,” each region possesses its own unique history and legends. The most famous are the spring waters remaining in Oshu City, Iwate Prefecture and Shinchi Town, Fukushima Prefecture, both of which have preserved traditions related to Minamoto no Yoshiie and the Zenkunen War.
Origins and Meaning of the Name
The name “Ippai Shimizu” has different origins depending on the region. The Ippai Shimizu in Iwate Prefecture is said to derive from water that Minamoto no Yoshiie discovered by digging to quench the thirst of his soldiers, with its name coming from the fact that the limited spring water was shared one cup at a time. On the other hand, “Ippai Shimizu” in Shinchi Town, Fukushima Prefecture, is said to have gotten its name from people repeatedly asking for “just one more cup!” due to its extraordinary deliciousness, and is also known as water of longevity.
Iwate Prefecture’s Ippai Shimizu | Legends of Minamoto no Yoshiie and the Zenkunen War
Historical Background and the Zenkunen War
The Ippai Shimizu located at Samukaze Pass in the southwestern area of Koganei District, Oshu City, Iwate Prefecture, is an important historic site related to the Zenkunen War (1051-1062). The Zenkunen War was a battle in which the father and son Minamoto no Yoriie and Yoshiie advanced to Oshu to subjugate the Abe clan, with many legends from the battles of that time remaining in this region.
Minamoto no Yoshiie’s Prayer and the Miracle of Spring Water
According to legend, when Minamoto no Yoshiie advanced his troops to Samukaze Pass, his retainers complained of thirst. Yoshiie prayed at the Hachiman Shrine and received an oracle from the deity saying, “There is spring water, so try digging.” When Yoshiie dug at that location with his bow and arrow, water sprang forth just as the deity’s oracle had promised.
This miraculous spring water is said to have quenched the soldiers’ thirst and raised the morale of the military force. From the fact that it was shared one cup at a time with care, the name “Ippai Shimizu” was given.
