Three separate flames, gathered from 62 municipalities across the host city, were combined into one during the ceremony.
"Each of the 62 wards, cities, towns and villages in the capital came up with an original way to collect fire," Tokyo Governor Yuriko Koike said during the ceremony, which was held behind closed doors amid the pandemic. "Now their representatives have brought their own fires and combined them into one - the flame of Tokyo."
Tokyo's flame will be combined with flames from other prefectures across Japan to make up the overall Paralympic flame. The scaled-down torch relay will then continue with the flame until the start of the Paralympics on Tuesday.
Japan has extended COVID-19 emergency measures in the capital and other regions that will run through the Games and, like the Olympics, the Aug. 24 to Sept. 5 Paralympics will take place generally without spectators.
