Like the Keicho Tsuho coin, an official minting record of this currency has not been confirmed, and there are some uncertainties such as whether it was issued by the Edo bakufu (Japanese feudal government headed by a shogun), whether it was privately minted Bitasen (low quality coins whose surfaces were worn away), the purpose of the issuance, etc.
この貨幣も慶長通宝と同様に正式な鋳造記録が確認されておらず、江戸幕府によるものであるか、民鋳の鐚銭であるのか、あるいはその発行目的など依然不明な銭貨である。
