Of course, the most interesting fact about the medals is that they're made out of recovered materials from used electronics. Between April 2017 and March 2019, people all over Japan donated their small electronic devices, from which officials could recover the gold, silver and bronze necessary.

According to the committee, engineers were able to recover 32kg of gold, 3,500kg of silver and 2,200kg of bronze -- 95 percent copper and 5 percent zinc -- from 78,985 tons of electronics. That figure included a staggering 6.21 million old mobile phones handed over at NTT DoCoMo stores across the country.
