The Japanese Army and Navy both used the Rising Sun Flag as their battle flag. The difference between the two uses was that the Navy one was offset from center toward the lanyard while the Army one was centered. This example is the Navy version. I also have a Hinomaru flag here. I have a smallish Jap collection, mostly because my grandfather fought the bastards. I think if I could find a nice farewell flag or a souvenir signed flag I’d be done.
