On the occasion of the Ojō Kōki, who was appointed as the lord of Osugasō, Shimousa Province, he was invited by Shinano Suwa Taisha Shrine as the god of the lord of the territory. He has since been revered as the god of industrial development, the god of wisdom, and in recent years as the god of advanced learning. The present main shrine is of the 1853 (Kaei 6) construction, and the annual festival "Sawara no Taisai (Autumn Festival)", which takes place in October every year, is designated as a national important intangible folk cultural property.

Western-style Mie-bashi, a masonry method, on the lower Nagao River at Takiguchi, Shirahama. Because there are three arches, it is not really glasses, but it has come to be called a glasses bridge from the appearance of moving to the river. The bridge was built in Meiji 21 (1888) with a donation of 399 yen and 40 yen from the villagers. He said he had walked across the river before the construction. It is a sturdy bridge that, in wartime, tanks passed through it without being broken by the Great Kanto Earthquake. Repair work was carried out in 1977 and 1993, and the figure remains at the time of construction. Prefectural Designated Tangible Cultural Property. Japan's Meihashi Hyakusyo.
