Medals for the Tokyo 2020 Olympic Games were unveiled at a ceremony marking one year before the start of the games in Tokyo.
The designs were chosen from more than 400 entries from professional designers and design students.
The medals, which each weigh from 450 to 556 grams, are being manufactured from metal extracted from mobile phones and other small electronics donated by Japanese as part of a campaign to make Tokyo 2020 eco-friendly.
The medals are engraved with images of the goddess of victory and the ancient Greek Olympic arena, with information, such as events, marked on the side.
The medals will come on ribbons that use traditional checkered Japanese patterns and graphics that symbolizes kimono layering techniques.
The intricate designs reflect patterns of light to symbolize the energy of the athletes and those who support them. The designs also reflect how athletes strive for victory on a daily basis, as well as the Olympic themes of diversity and friendship.
