Ogi-island in the Seto Inland Sea has a unique landscape with stone retaining walls and alleys. With depopulation and aging, the quantity of open spaces increased. As the stone wall degrades, the landscape heritage is threatened. We clarified the characteristics of the landscape by its facade and alley configuration. The study finds that the stone wall has a high heritage and aesthetic value, but is threatened by modern repairs. Three alley types were identified namely, V Alley, U Alley and L Alley.
