Banknotes of the Japanese yen are the banknotes of Japan, denominated in Japanese yen (¥). These are all released by a centralized bank which was established in 1882, known as the Bank of Japan. The first notes to be printed were released between 1885 and 1887 in denominations of 1 to 100 yen. Throughout their history, the denominations have ranged from 0.05 yen to 10,000 yen. Banknotes under 1 yen were abolished in 1953, and those under 500 yen were discontinued by 1984. Higher end notes of 1000 yen and more made their appearance in the 1950s. These continue to be issued to the present in ¥1000, ¥2000, ¥5000, and ¥10,000 denominations. The formerly used notes of 1 to 500 yen from 1946 to the 1980s, while discontinued, continue to be valid. These are, however, worth more than their face value on the collector's market.
At present, Japanese banknotes are printed with portraits of people from the Meiji period and later. This is because it is desirable to use an accurate photograph as the original for a portrait, rather than a painting, in order to prevent counterfeiting.
