Tokyo 2020 organisers have conducted an earthquake drill at Ariake Gymnanstics Centre, in preparation for next year's Olympic and Paralympic Games.

Around 650 participants took part, including Tokyo Metropolitan Government officials, local police, firefighters and self-defence forces.

The large-scale drill was based on a 7.3 magnitude quake, hitting the metropolitan area at 9.15am on July 26 next year, with events scheduled across 20 venues.

While only 350 spectators took part, organisers were pleased with the results.

"Firstly, I think we have achieved most of our primary purposes of this drill," said the city's director of security, Hiroya Yarimizu.

"As the most important aim, we focused on how the Olympic Organising Committee and Tokyo (Metropolitan Government) could interact with each other.

"The police, firefighters and Self Defence Forces (SDF) joined the drill this time and I think we all communicated well."

At Tokyo's waterfront area, announcements in English and Japanese urged the participants to stay calm, while firefighters gave first aid to those injured as security guards helped people to evacuate.

Around 150 drill participants were also taken to a park and given bottles of water, at a designated temporary evacuation site.

Wheelchair users were also involved, with those visually impaired linking arms with officials to evacuate.

"I would like everyone to do everything possible to handle the situation and to offer support to both domestic and overseas visitors," Tokyo Governor Yuriko Koike told participants.

Japan is historically vulnerable to earthquakes, typhoons and tsunamis - in March 2011, a massive quake and tsunami devastated the east coast, killing almost 18,000 and triggering a meltdown at the Fukushima nuclear power plant.
