Chiw-pet and the old name Chūbetsuチゥ ペッと旧称「忠別」
Before 1890 the area was called Chūbetsu, after the Ainu name of the Chūbetsu River. The city museum’s first Ainu place-name sign (2003) writes the river’s name as Chiw pet; a later sign at the Kitasaito Garden (2018) uses Chuk pet. The Kawamura Kaneto Ainu Memorial Museum still gives its address in Ainu as Yaunmosir Chiwpet-kotan.[13][14]
