HOW TO ENTER
Please enter the contest according to the following guidelines.
(1) Entries shall be unpublished and original. There is no limitation on the number of entries per person.
(2) When submitting via post, please use A4 landscape (210mm long by 297mm wide) white drawing paper and draw your design within a circle, as mentioned below. Please keep approximately 1 cm wide blank within the circumference because the rim of the coin will be drawn on this space. Entries with no such blank space may be adapted by the Japan Mint for use as a coin design.
(a) For the gold coins, the diameter of the circle is 13cm.
(b) For the silver coins, the diameter of the circle is 16cm.
If you were born on or after April 2, 1996, it is not necessary to draw your design within a circle. In this case, however, please still try to draw your design within the size of the circle mentioned above, because the design will be cut out into a circle of the size mentioned above by the Japan Mint.
(3) When submitting via e-mail, please draw a design according to the above article (2), to be printable on A4 paper. The format and other materials are available HERE ( gold / silver ). The entries shall be in the following format:

(b) The resolution shall be approximately 350 dpi or more so as to ensure the reproducibility of the design.

The Japan Mint will print the entries on paper and submit them for preliminary screening, to be conducted by the Ministry of Finance and the Japan Mint.
