知床半島
Among the approximately five hundred and thirty "chashi" identified by archaeologists, the sites of eight have been designated national Historic Sites: the Otafunbe "chashi"; Shibechari River "chashi" and Appetsu "chashi"; Moshiriya "chashi"; Yukuepira "chashi"; Katsuragaoka "chashi"; Nemuro Peninsula "chashi"; and Tsurugataicharanke "chashi". Others known include the Arashiyama "casi", Harutoru "casi", Onibishi's "casi", Sarushina "casi", Sashirui "casi", Setanai "casi", and Uraike "casi". Although there are nineteen "chashi" on the Shiretoko Peninsula, it is inscribed as a Natural rather than a mixed Natural and Cultural UNESCO World Heritage Site.
