South Pacific Mandate Monetary Context
Japanese yen became legal tender in the mandate; national Japanese coins remain circulation evidence rather than mandate-issued coins.

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.

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 Pacific Mandate
Japanese yen replaced the prior German-mark environment and became legal tender.
- South Pacific Mandate
Japanese administration ended; later trust-territory systems used the United States dollar.
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.
