Comments

This coin is an imitation of the Chinese Yong Le Tong Bao and circulated alongside a large quantity of imported Chinese originals known as a toraisen. Japanese made coins are scarce today and distinguishing them and the imported coins is quite difficult. Dark copper alloys are said to be more frequent in Japanese coins and craftsmanship ranges from nearly Chinese quality to poorly made bitasen DHJ# 2.97-98 and 3.19.
Ming dynasty inscription coins were officially prohibited by the Tokugawa shogunate in 1608 but bitasen continued to circulate until 1670 replaced by the more favoured Kan'eitsūhō.
