The 2020 Olympic medals are going to be made from old mobile phones and other electronic devices.
Around 5,000 gold, silver and bronze medals will be made for the Olympic and Paralympic Games in Tokyo next year.
Since 2017, organisers in Japan have been asking people to donate old phones and devices.
Millions have been handed in, and they will stop taking donations next month.
Organisers plan to use metals from the phones to make thousands of medals.
The project was an attempt to promote recycling, and get Japanese citizens involved in the Olympics.
The Tokyo Olympics summer games will take place in July and August 2020.
It will be the first time the Japanese capital has hosted the Games since 1964.
