SANGAKU is a wooden board dedicated to the temple and shrines with written math questions and answers. This paperis a survey report of the two SANGAKU in Obara district, Shiroishi city, Miyagi prefecture. One of them is in Manzo-Inari Shrine, and was originally dedicated to Mitaki Shrine in 1875. The other was displayed in the Katsura-ya Hotel, and was originally dedicated to Obara-Onsen-Yakushido Temple in 1916. They were dedicated by the people of the Saijo school (one of the old Japanese style mathematics school) and are rare in Miyagi. We surveyed these SANGAKU in the fall of 2020, took pictures with digital camera and infrared camera, and checked the characters visually. In this paper, we will present the survey summary, consideration on some math questions, consideration of the reason why Saijo school was popular in this area, reprints, and infrared photo of figures.
