The young-tree motif is paired with the national inscription and the denomination. Japan Mint says the artwork was selected through a public design competition for the new aluminum 1 Yen coin.

Numeral & Shōwa Date Side

The opposite face bears the numeral 1 and a year inscription using the Shōwa era. The date on this issue is 昭和五十一年.

Historical Context

The aluminum 1 Yen coin first circulated in 1955. Japan Mint historical materials describe the decision to reintroduce this small denomination after the earlier brass version had been discontinued.

Source discrepancy: The Japan Mint official manufacturing table gives 928,850,000 for 1976, whereas the supplied Numista catalogue lists 928,800,000. This archive retains both figures and uses Japan Mint as the primary source. Do not silently substitute or combine them.
