Thank You! That was exactly what I was looking for.

Is that measurement land only, or does it include air and sea territory? Additionally is the land mass limited to that which was actively occupied or does it include those land masses passively occupied with landmines or controlled by isolation? I ask because the majority of Japan's holdings were strategically located islands. By skipping uninteresting islands Japan was able to conserve men and resources effectively controlling those unoccupied islands by isolation. This strategy also helped them to keep the Allies guessing where they really were and as opposed to where they simply controlled by default. An example of the extent of sea and air controll held by occupation of two closely oriented islands (with satellites) Look at Batanes, PI on a map.

The province is located between the pacific and the china sea, closer to Taiwan than the main island of the Philippines. The provincial capital Basco has the only safe port in the middle of some of the worst water commonly travelled. One can actually see Taiwan on a clear day. The entire province has only 20,928 hectares of land mass, but the sea territory that can be defended from it is substantial. Once this province was abandoned by the Japanese in 1946, the Americans set up a small monitoring station on the south side of the main island. Ruins of it still stand.
