About

The Nemuro Peninsula Chashi Sites consist of twenty-four historically significant Ainu fortifications, known as chashi, situated on the Nemuro Peninsula in Hokkaidō, Japan. These defensive structures, dating from the 16th to the 18th centuries CE, are strategically located on bluffs that provide a commanding view over the Sea of Okhotsk. They are characterized by their U-shaped or semicircular moats, which served as defensive barriers. The sites are well-preserved and reflect the Ainu's strategic use of the natural landscape for protection. Notably, these chashi are linked to the 1789 Menashi–Kunashir rebellion, highlighting their role in regional conflicts. Their inclusion in Japan's Top 100 Castles underscores their cultural and historical importance.
