Ominato.
Ominato, on the north coast of the principal island, is a torpedo-boat base. The town lies in a huge bay (Rikuoko Bay) that runs out of the Tsuguru Straits, on the opposite shores of which Hakodate stands.
The country is very mountainous, the highest peak being 3264 feet high, and the lower ones seldom less than a thousand feet.
In the war the Russians once passed through the Tsuguru Straits, but it was a risky proceeding.
