Sakhalin tip

The south end of Sakhalin round Aniva Bay is the last of the Ainu-Okhotsk world before the Nivkh country begins in the north.

It faces Hokkaido across the narrow Soya strait; the people fish and hunt and trade with the Hokkaido villages and with the Amur peoples. The Mongol notices of 1264 and after call the island's people Kuyi (Kuye) and are far later. Sakhalin north of about 46.4 N lies beyond this sheet's frame (anchors only).
