The , commonly known as the Proof Set in the United States, is a set of proof coins sold by the Japan Mint. These sets were first issued in 1987 (Shōwa 62) as "regular proof sets" consisting of denominations of 1, 5, 10, 50, 100, and 500 yen (666 yen total). In addition to "regular", those made since 1997 have also been referred to as "special", as these sets include a decorative case and in some instances a non-legal tender medal. Proof coinage is not intended for circulation as these are targeted towards collectors.
