Ever saw the movie "None But The Brave" (1964) by Frank Sinatra? Japanese title: 勇者のみ Yūsha Nomi
There were quite a few scene showing Lt. Kuroki' s IJA officer's cap (his right side, behind the chin-strap button) with his name キロク stitched on. (words were read and written from right to left at that period, nowadays is from left to right so in this case クロキ Kuroki.
It's a very interesting movie about a transport plane with bunch of U.S. Marines crash-landed on an island occupied with small Japanese forces.....
