JPN

JPN is a three-letter code used to designate Japan in several international coding schemes. The ISO 3166-1 alpha-3 code for the country is JPN, and it appears in statistics, shipping data, and other datasets to refer to Japan. The same sequence is used as the national code by international sports organizations; for example, the International Olympic Committee and FIFA assign JPN to Japan's national teams and athletes.

In language tagging, the three-letter code for the Japanese language in ISO 639-2 and ISO 639-3 is jpn, typically shown in lowercase. Some databases display it in uppercase as JPN, but they refer to the same language code.

JPN should not be confused with JPY, the currency code for the Japanese yen. It is also distinct from internet domain references and other acronyms.

In practice, JPN functions as a shorthand in datasets, travel itineraries, and competition results, reflecting standardized codes that support global interoperability.
