Are there any common Japanese words which were borrowed from Ainu or other indigenous languages?


I know plenty of Japanese words that came from English and a few from other
European languages (obviously tons from Chinese), but what about words from
Japan's indigenous languages such as Ainu? Also if there are any are they all
written in kana like the newer borrowed words?




What I think common from them is
[トナカイ](http://ja.wikipedia.org/wiki/%E3%83%88%E3%83%8A%E3%82%AB%E3%82%A4)、[ラッコ](http://ja.wikipedia.org/wiki/%E3%83%A9%E3%83%83%E3%82%B3)、シシャモ、ノンノ
