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. 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.
