Quick brush-up on WWII history.
On August 6, 1945, the Enola Gay, a B-29 bomber, dropped an atomic bomb nicknamed "Little Boy" over the center of Hiroshima, Japan at 8:15 am. Three days later on August 9th, a second atomic bomb nicknamed "Fat Man" was detonated over the city of Nagasaki, effectlively ending WWII. Japan's formal surrender came 24 days later when the "Japanese Instrument of Surrender" was signed on September 2, 1945, aboard the U.S. Navy battleship USS Missouri in Tokyo Bay.
How this relates to Toyota: the Hiroshima Toyota Motor Sales Co. Ltd. Building was destroyed by the first bomb.
In the aftermath, Toyota was determined to rebuild operations. They relocated and began reconstruction under the name "Toyota Sales Co. Ltd.” approximately one year later. The date reconstruction was complete is unknown .
This copper container and matching tray was produced to commemorate the completion of the Hiroshima Toyota renovation. How many years it was made after completion is also unknown, but Toyota has commissioned many other items to mark the 10th anniversary of significant company events. We don't know if it dates to the late 1940's (shortly after the new Hiroshima Toyota was completed), its 10th anniversary, or sometime after that. I speculate it was in the 50's.
Box and tray are crafted of hammered copper with what appears to be riveted brass inlay. The container measures 6 1/2" x 4", the tray 9" x 6 1/2". The top stamp on the underside of the tray tanslates loosely to "Hirosima Toyota Reconstruction Commemoration". I believe the bottom two characters translate to "Copper <something or other>". Can't quite make out the second character, but it could be, believe it or not, "Bug". If it is, I don't know how it relates. It really is a nice piece and exudes Toyota quality.
