Tokyo Gov. Yuriko Koike vowed Friday to use the 2020 Tokyo Paralympics to create a city that can cope with the demands of a rapidly aging population.

Graying Japan is one of the world's fastest aging societies, with the number of centenarians rising to 65,692 in September, an increase of 4,124 from the previous year.

Tokyo is under pressure to update its creaking infrastructure to deal with its aging population, but Koike said she believed the 2020 Olympics and Paralympics can provide the catalyst to transform the city.
