Minamiabashiri
The inland Abashiri country lies north of the Akan mountains, along rivers flowing toward Lake Abashiri and the Sea of Okhotsk. Ainu settlements occupied this wooded region, whose river valleys offered a passage between the interior and the coast. Between 1808 and 1810 a route was opened from Shiranuka on the Pacific side, across the Akan district and down the Abashiri River toward the northern shore.
