Start Your Stroll at a Symbol of the Castle Town with Stone Walls and Main Gate
About this spot
A park that preserves the site of Usuki Castle (臼杵城), built by the Sengoku-period warlord Ōtomo Sōrin (大友宗麟). Once an island called Nibu Island (丹生島) floating in the sea, the park retains historic structures including stone walls, the tiled turret, and the Ue-Tora Gate turret. The park grounds display a statue of Ōtomo Sōrin and a replica of "Kuni Kuずし" (国崩し), one of Japan's largest cannons. From the elevated vantage point, you can overlook Usuki's castle town and sea, making it perfect for a morning stroll in the crisp air. Also known as a cherry blossom viewing spot, the trees provide pleasant, cool shade. As a starting point for historical sightseeing, it's a park where families can stop by casually.

佐志生港までは車でのアクセスが基本です。渡船の最終便は18時なので、着替えや片付けの時間を見込んで17時台には切り上げるのがおすすめ。売店は7月4日から8月末頃までの営業なので、それ以外の時期は飲み物や軽食を持参しましょう。日陰が少ないため、テントやパラソルがあると快適です。
