1 Monme

Ashimori was a small fudai domain in Bitchu Province (modern Okayama Prefecture), holding a assessed yield of just 25,000 koku — modest even by han standards. Domain-issued paper currency, hansatsu, allowed local lords to effectively borrow against future tax revenue while keeping metallic coin within domain borders. The monme denomination places this firmly in the silver-unit system of western Japan, distinct from the gold-based ryo denominations more common in Edo-area issues.

1730 falls within a period of widespread hansatsu proliferation following the Kyoho economic reforms, which paradoxically drove many smaller domains toward paper as silver coinage tightened.
