The Ishiyama-dera Temple and the Provincial Monastery of the Omi Province (Kokubun-ji Temple) were around there and Omi Kokucho (provincial government office of Omi) was on the opposite side of the Seta-gawa River, so the environment was well-ordered, and in Kokubu 2nd street, there is a stone called 'Heso-ishi' (navel stone) which was allegedly one of the foundation stones of Horanomiya.
周辺には石山寺や近江国分寺、瀬田川対岸には近江国庁があり環境も整っており、国分2丁目には「へそ石」とよばれる保良宮の礎石の一つと伝えられている石が残っている。
