The 10,000 yen coin, measuring 26 millimetres across and weighing 15.6 grams, is designed with an image of the Expo's official character, Myaku-Myaku and the Japan Pavilion. The 1,000 yen coin, 40 mm in diameter and weighing 31.1g, will include an image of the character and a rainbow. It was revealed in April that the 500 yen coin will also feature the Myaku-Myaku character. Japan Mint plans to sell 1,000 limited sets that include all five coins from the three instalments for 344,000 yen, available to order from next March. If the orders surpass the number of planned sets, it will hold a lottery.
