Overview

Oshika Cobalt Line — Ishinomaki to Ayukawa Whaling Coast.

The Oshika Cobalt Line traces the forested ridge of the Oshika Peninsula, Miyagi's remote finger reaching into the Pacific. This day ride links the rebuilt tsunami-coast towns of Ishinomaki and Onagawa with an old whaling port at the peninsula's tip, on a quiet ridge road with views over Sendai Bay and the sacred island of Kinkasan.
