This paper is a study on Sangaku Dedicated to Kumano Shrine in Semine-Izumiya, Kurihara City, Miyagi Prefecture. Currently, two Sangaku are kept at Kumano Shrine. These were created in 1986 and are restorations of the old Sangaku. In September 2023, we had the opportunity to investigate these. As a result of investigating the basis on which these were created, we were able to uncover the contents of the Sangaku that were originally dedicated. And it is different from the restored sangak that exists today.
