The medals presented to Japan Prize laureates were designed in 1985 by Yusaku Kamekura, who was President of what was then the Japan Graphic Designers Association Inc.. The medals were then cast specially at The Japan Mint.
Kamekura described the thought process behind his work when he said, “The Japan Prize is designed to be reminiscent of the Sun. The Sun is a source of energy and is a circle, a shape that evokes the ideas of perfection and truth. So, I thought it appropriate for an award given for achievements in science.”
Kamekura also designed the certificates of merit that laureates receive. Each certificate is inscribed with the recipient’s name, their achievements, and the following citation:
"WHEREAS, you have advanced the frontiers of knowledge by your original and outstanding achievements in science and technology, and WHEREAS, you have thereby significantly contributed to the progress of the cause of peace and prosperity of all mankind.
THEREFORE, the Japan Prize Foundation, with deep respect for your manifold accomplishments, bestows upon you the Japan Prize."
