Keicho Tsuho

Japanese: 慶長通宝 - けいちょうつうほう

Coin coins (copper coins, 1 mon in value) minted by the Edo Shogunate around 1606 (Keicho 11). There were two types, large and small, the former being high-quality coins and the latter being coins descended from bitasen. The former were minted in Edo or Kyoto, the latter in Kansai and west. In 1608 and 1609, the Shogunate banned the use of Eiraku coins, which had been currency since the Middle Ages, but this was not realized. In an edict of 1609, the Shogunate established the exchange rates of the three currencies as follows: 1 ryo of gold = 50 momme (momme) of silver, and 1 kanmon of Eiraku coin = 4 kanmon of Kyo coin.
