The 100 yen coin (百円硬貨, Hyaku-en kōka) is a denomination of Japanese yen. The current design was first minted in silver in 1959 and saw a change of metal in 1967.[1] It is the second-highest denomination coin in Japan after the 500 yen coin. The current 100 yen coin is one of two denominations which depict the emperor's rule date in Arabic numerals rather than Kanji. These numbers go from "昭和42" Shōwa, 42nd year of reign (1967) to "令和2" Reiwa, 2nd year of reign (2020).


Silver yen

100 yen coinage was first authorized in 1951 with the specification that the coins be made of a silver alloy.[2] The first coins were minted for circulation in 1957 which featured a phoenix on the reverse. The alloy decided upon consisted of 60% silver, 30% copper, and 10% zinc and came at a time when banknotes of the same denomination were already in circulation.[3] The "100 yen" bill hence became a substitute to the coin as the two were allowed to co-circulate.[4] The design of the coin was changed in 1959 which removed Latin script ("Yen"), and changed the reverse side to show a sheaf of rice. To commemorate the summer 1964 Olympics in Tokyo 16 million ounces of silver was used to strike the 80,000,000 coins produced. None of these coins were recorded as ever going into circulation as they were grabbed and stored away as collectors items.[4] The usage of silver worldwide for coinage was about to take a turn though, as the price of the bullion increased dramatically. The Japanese government had planned on producing 800 million silver coins over a 10 year span[a], but the amount of silver held was insufficient.[5] Silver was dropped from the coinage in 1967, which led to coin hoarding and silver smuggling outside of the country for melting.[6]

Cupronickel yen

The new and current design of the 100 yen coin debuted in 1967, and features sakura blossoms and the denomination in Japanese. A new alloy of 75% copper and 25% nickel (cupronickel) was decided upon to replace the former silver alloy. It was reported that by 1969 the monetary value in the old silver coins was $3 (USD) an ounce, prompting a "coin retirement" plan by the government.[7] On August 1, 1974 one hundred yen notes were withdrawn from circulation, but post World War II dated notes were allowed to retain their legal tender status.[8] The amount of coins produced then decreased from the mid to late 1970's as a possible attempt to control economic inflation.[6] The issuance of the new 100 yen coin has also been cited as a factor in the rapid spread of vending machines during this decade.[9] By the late 1970's into the early 1980's a myth was established that tied the amount of coins produced with the growing popularity of the arcade game industry. While there were reports of Japanese cities briefly running out of 100 yen coins, arcade operators would have emptied out their machines and taken the money back to the bank which kept the coins circulating.[10][11]

Production of the 100 yen coin dropped going into the mid 1980's due to various proposed reasoning. Japan at the time had been in economic decline caused in part by trade tensions with other countries that were competing with Japanese exports.[11] The Japanese government was trying to deflate the yen, and achieve more imports and less exports. Another explanation put forward is the introduction of the 500 yen coin in 1982. The Japanese mint at the time stated that a higher value coin was needed for use in vending machines.[11] In any case mintage figures recovered towards the very end of Emperor Shōwa's reign. No coins were minted in 1989 (year 64) as molds needed to make coins for Akihito had already begun.[12] Denominations of 1, 5, 10, and 500 yen were given priority over 50 and 100 yen coins.[12] By the mid 1990's 100-yen shops were expanding into retail chains, these "shops" are akin to American dollar stores. Coin production remained unhindered during the early years of Akihito's reign until the millennium, when 500 yen coins were turned out in record numbers. The offset caused low mintage numbers which included only 8,024,000 pieces struck in 2001, a record low for the series.[13] The '100 yen" coin continues to be produced to the present day as the second-highest denomination of yen coinage.
