The medals to be awarded to athletes in the 2020 Tokyo Olympics will me made from discarded electronic devices, said organizers of the international sporting event.
Japanese citizens are being asked to give the organizing committee unwanted devices.
Organizers say the program highlights the theme of sustainability and gives the whole nation a chance to participate in the preparations for the games.
The organizing committee aims to collect as much as eight tons of metal which, after the production process, will result in two tons, an amount needed to produce 5,000 Olympic and Paralympic medals.
Collection boxes will be set up throughout the country. The collection will end when the eight-ton target is reached.
