The standard currency in use during the period was the Eiraku tsuho (Chinese Ming-dynasty copper coins); the Muromachi bakufu never minted its own coins, instead importing these Ming copper coins by means of Japan's trade with Ming China and then having them circulate.
標準貨幣は永楽通宝であったが、室町幕府は貨幣を鋳造せずに日明貿易で明銭を輸入して流通させていた。
