Akaigawa (赤井川村, Akaigawa-mura) is a village located in Shiribeshi, Hokkaido, Japan.

The name derives from Ainu word "hure-pet", meaning "red river".

[4] Per Japanese census data,[1] the population of Akaigawa has declined in recent decades.

Akaigawa's mascot is Akarin (あかりん), a 10-year-old farmer girl who is active day and night either through sports or farming.

She usually ends her sentences with "desu no" (ですの) which, along with her eyes, are her charm points.
