The name Osakamoto Oji derives from its location. It is locates at the foot of Osaka Pass. Moto means"foot", so the word Osaka(big slope)was combined with the word moto. The path leading down to Osakamoto Oji is steep,so travelers are rilieved to walk over a flatter trail after reaching the ruins. There seems to have been a small shrine building in the Edo era and some foundation stones of the building and the stumps of big trees still remain. At present only a Kamakura style stone stupa tower remains. There is a solemn atmosphere at these ruins.
