At first sight nothing out of the ordinary in this quite well-made “B-29” wooden mock-up. Looks just like another airfield decoy, don’t you think?…,wrong. Taken at the Irumagawa AB (Japan), this was one of the three full-size B-29 mock-ups constructed in Japan during the war. Another, the one at the Imperial Japanese Army Academy at Saitama, was employed as a demolition trainer to develop the tactics to be employed for the “Operation Gi-gou” on Okinawa.
