The event, which lasts for five days, with be the biggest competition for nearly two years for the British diving team.
The competition, which is being held at the newly-built Tokyo Aquatics Centre, is a test event for this summer’s Olympic Games, with some qualification spots still up for grabs.
Former world champion Daley will be in action on the opening day when he competes in the 10m synchro event with Matty Lee. The pair will be hoping to claim another global medal having won bronze together at the 2019 World Championships.
Dixon will be in action on Monday when he competes in the 10m individual event alongside Daley.
Dixon, who recently turned 21, will be hoping to try and push his claims for a place in this summer’s Olympic team by impressing on the global stage.
Former Plymouth divers Robyn Birch and Dan Goodfellow are also part on the British team in Tokyo.
Ahead of the competition, high performance centre head coach Jane Figueiredo said: “We are excited and raring to go. It’s been a long journey for everyone, but the divers have shown grit and resilience throughout Covid times, and I think we have prepared to the best of our ability.
“We are ready to compete and measure ourselves against the rest of the world – and we are looking forward to putting in the work and the performances required to pick up the rest of our Olympic quota spots.
“This event is always significant, but this year it’s also one for Japan to test an event in the Tokyo Aquatics Centre venue ahead of the Olympic Games. It’s important for us to get a competition in the venue to acquaint ourselves with the pool environment and feel comfortable in the surroundings, which is key for our divers.”
