Futuristic characters Miraitowa and Someity, selected by Japanese school children, have been unveiled as the Tokyo 2020 Olympics and Paralympics mascots.

Unveiled at a ceremony in downtown Tokyo, the Olympics mascot is named Miraitowa, while the Paralympic mascot will be known as Someity.

Miraitowa is a combination of the Japanese words for future and eternity.

Someity comes from a popular cherry blossom variety “Someiyoshino” and echoes the English phrase “so mighty”.

The two mascot designs were selected by elementary school children across Japan.

The selection process involving school children was introduced to get students enthusiastic about the Games while also ensuring transparency.

Organisers said the pair of futuristic characters combine tradition and innovation.

The Tokyo Olympics are scheduled for July 24 to August 9, 2020.
