Nemuro Peninsula Chashi Sites
Nemuro Peninsula Chashi Sites is a grouping of twenty-four Ainu chashi on the Nemuro Peninsula in Nemuro, Hokkaidō, Japan that have been jointly designated a national Historic Site, out of a total of thirty-two chashi sites identified in the city. The grouping is also the first entry on the Japan Castle Foundation's 2006 list of Japan's Top 100 Castles. Typically found at elevations of to above sea level, they are mostly situated on bluffs overlooking the Sea of Okhotsk, reinforced with U-shaped or semicircular moats. Relative to many of those elsewhere on the island, their state of preservation is good. They are thought to date from the sixteenth to the eighteenth centuries, and are associated with the 1789 Menashi–Kunashir rebellion.
