A marriage spot in Shiroishi
It is located between the Shiroishi Castle and the Sawabata River that feeds the outer moat of the Castle's San-no-maru ward. It is revered as a "Stone where the Kami Dwell."
People say that the stone's roots are so deep that they run from Shiroishi to Nenoshiroishi in Izumi-ku, Sendai City. And, similar to how the two distant stones are connected, people say that if one prays for a happy marriage at Shinseki Shiroishi, their prayers are fulfilled.
