Canonical Korea context keeps Korean Empire issues, Japanese colonial circulation, and postwar reform in their correct systems.

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.

Political control

Who exercised power over the jurisdiction.

Legal jurisdiction

The territory or state in which the system operated.

Issuing authority

The government, central bank, colonial bank, or regime bank responsible.

Currency system

The unit, parity, legal-tender basis, and note/coin layers.

Producing mint

A manufacturer may produce for a foreign issuer without owning the issue.

Canonical catalog

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.

  1. Korea under Japanese rule

    The Bank of Chosen became the colonial note authority; pre-annexation Korean Empire coins remain canonically Korean.

  2. Korea under Japanese rule

    The Bank of Korea inherited note circulation while Japanese subsidiary coins remained temporarily in use.

  3. Korea under Japanese rule

    The hwan reform ended legal use of Bank of Chosen notes and Japanese one-jeon coins.

    100 won = 1 hwan

Context only

Banknote systems are not coin objects

Bank of Chosen

Bank of Chosen yen notes are contextual; Japanese subsidiary coins remain Japanese issues.

Excluded from coin issue count
Evidence boundary

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.
