This one sen was struck in [[Japan]] during the reign of the Showa emperor, Hirohito (1926-89). The type was struck 1927-38; this date is common. Prior to the opening of Japan in the 1850's and 1860's, Japanese coins were a mix of Chinese-style cast copper cash, silver rectangular "bu" and rare, gold "oban."  The last one sen coin was issued in 1945, as B-29's rained death on Japanese cities.
