The dockyard lies at the foot of a picturesquely wooded hill, in the Bay of Tokio, and is well defended by sea forts. To the landward the defence is, however, poor, and Yokosuka could be taken by an army that could secure a foothold on the southern coast, supposing it able to defeat the defenders.

At Tokio, roughly twenty-five miles from Yokosuka, there is a small dry dock belonging to the Japanese Government. It is, however, only suitable for gunboats and destroyers.
