After World War II, the Allied forces occupied Japan for seven years. During the occupation period, most Japanese goods imported to the U.S. carried this mark, but not all. Today, collectors prefer and pay more for collectibles marked "Occupied Japan."
During the Occupation period, from 1945 to 1952, U.S. customs required goods imported from Japan stamped with "Occupied Japan." Many U.S. military men stationed in Japan brought these goods home as souvenirs.
Look for marks under porcelain and china goods, or marked somewhere on other products like clocks. Marks should include the words "Occupied Japan" or "Made In Occupied Japan."
Except for Japanese Noritake, Occupied Japan goods imported to the U.S. often copied similar, more expensive European products. Although mass-produced, these postwar Occupied Japan products were of good quality.
Occupied Japan-marked products included porcelain and home goods like tea sets, dinnerware, bisque figurines and lighters.
According to Kovels.com's monthly report, more collectors searched for "Occupied Japan" than any other collectible in 2009.
