During that time Japan was ruled by fierce Shogun warlords employing highly skilled samurai armies. Paper money was first issued in Japan in the early seventeenth century, when serious shortages of coins arised. During the Edo period many local clans, merchants, communities and banks issued their own currency.
These tall, thin notes (approximately 6" x 1.5", 160mm x 40mm) were hand-printed on heavy paper with woodblocks by local artisans. These Hansatsu scrip had a face value in silver coinage, but gold and copper scrip also circulated. In addition, some scrip was marked for exchange in kind for a commodity such as rice, wine or oil.
Counterfeiting was discouraged by severe punishment, as well as by elaborate techniques such as watermarking and the use of special hidden characters. In fact, the artisans who made the paper money had to sign an oath of secrecy in blood, promising not to reveal any of these anti-counterfeiting measures.
