Between Tomakomai and Noboribetsu on the south coast in central Hokkaidō, Shiraoi's Poroto Kotan (ポロトコタン) is a lakeside village of reconstructed traditional Ainu buildings, anchored by the Ainu Museum. Museum exhibits are labelled in both Japanese and English, and in the village you might catch demonstrations of Ainu crafts and cultural performances. The museum is particularly interesting but unfortunately the animals in the village are kept in very poor conditions.
Shiraoi is on the JR Muroran line.
