Identity first
Control is not the same as issuance
Every record keeps six relationships visible. This prevents a Japanese minting or control relationship from overwriting the issuer and jurisdiction printed into the coin's history.
Who exercised power over the jurisdiction.
The territory or state in which the system operated.
The government, central bank, colonial bank, or regime bank responsible.
The unit, parity, legal-tender basis, and note/coin layers.
A manufacturer may produce for a foreign issuer without owning the issue.
The country or historical jurisdiction under which the coin belongs.
Political geography
Jurisdiction and canonical identity
The canonical country field governs catalog ownership; the controlling-power field preserves the political relationship.
| Jurisdiction | Political class | Control | Canonical catalog | Span |
|---|---|---|---|---|

Authority hierarchy
Issuer, note bank, administration, and mint
A dash means the authority did not perform that issuing role; it does not mean the authority was absent from the wider system.
Currency layers
Coins and banknotes are modeled separately
Taiwan and Korea had territory-specific note systems while using Japanese metropolitan coins. Karafuto and the South Pacific Mandate used the Japanese yen directly. Manchukuo had a separate yuan system.

Change over time
Currency transitions
Adoption, parity, succession, and withdrawal are distinct events. A conversion rate appears only when a cited source states it.
- South Karafuto
South Karafuto was legally integrated into Japan's home jurisdiction without a new territorial coinage.
Japanese control does not make a foreign coin Japanese. Japanese use abroad does not create a colonial coin issue. Mint production does not prove circulation. No occupation countermark is published without institutional evidence.
