10000 Yen - Teller Practice Banknote

Training notes produced for bank teller instruction in China have long used foreign currency designs as practice material — employees needed to learn detection of counterfeits and handling procedures for currencies they might encounter in exchange transactions. This example using the Japanese 10,000 yen format makes practical sense given the volume of cross-border commerce between China and Japan, particularly from the 1990s onward.

These were never legal tender in any jurisdiction. Chinese-produced teller training notes of this type are untracked by most major catalogs, which makes provenance and precise issue dating difficult to establish with confidence.
