The Ichigaya section of Tokyo was the location of the Imperial General Headquarters (IGHQ).
At the conclusion of World War II, it was the site of the International Military Tribunal war crimes trials. The area was subsequently renamed "Pershing Heights" and, from 1952 to 1957, was the location of the headquarters of the United Nations Command and the Far East Command.

I have not been able to identify this building. However, I believe it was located in Pershing Heights.
