The flame was handed to Tokyo Governor Yuriko Koike at the Komazawa Olympic Park stadium, just two weeks before the start of the games.
The event was held a day after Japan announced that no spectators will be allowed at the Tokyo Olympics due to the worsening COVID-19 situation in the country.
The Olympics will be held from July 23 to Aug. 8, followed by the Paralympic Games from Aug. 24 to Sept. 5.
