DENOMINATION GUIDE — WHERE & WHEN (coins catalog: by names & emitents)
  1. JAPAN (1870-Present): 1 yen = 100 sen = 1000 rin.
Note: Fractional units (sen and rin) were officially withdrawn from circulation in 1953. While the yen was used in colonial Korea and Taiwan, local circulating coins for these regions were typically issued as sen units.
YEN (EN) as a currency name: Rooted in the Chinese word yuan, meaning "round." In Japanese, the character is pronounced "en." The term "yen" became global due to 19th-century Western phonetic interpretations. Despite this, the Japanese traditionally refer to their currency simply as "en" (円).

Evolution of Japanese Coinage

The yen was established in 1871 during the Meiji Restoration, replacing the fragmented feudal system with a unified decimal structure modeled on Western standards. Originally, the system was bimetallic, with high-purity gold and silver coins intended for international trade.

As the 20th century progressed, precious metals were gradually phased out. The 100 yen silver coin of 1958 represents the final era of circulating silver in Japan. By 1967, the rising price of silver led to a total transition to cupronickel for this denomination. For numismatists, these Shōwa-era silver coins are a bridge between the classical imperial designs and the modernist aesthetics of contemporary Japan.

Modern Circulation and Practical Use

Following post-World War II hyperinflation, the yen became the sole practical unit for daily transactions. Today, Japanese coinage is noted for its distinctive functional designs:

  • 5 and 50 Yen: Feature central holes for easy tactile identification.
  • 1 Yen: Struck in pure aluminum; it is famously light enough to float on water.
  • 500 Yen: One of the highest-value circulating coins in the world, often featuring sophisticated anti-counterfeiting latent images.

From the intricate dragons and phoenixes of the early eras to the clean symbols of the current Reiwa period, the Japanese yen remains a rich field of study, reflecting the nation's rapid economic and cultural transformation.
