TOKYO - Olympic organizers say millions of Japan residents have shown interest in buying tickets for next year's Tokyo 2020 Games.

Organizers closed the first phase of ticket applications on Wednesday for Japan residents, and applicants will be told on June 20 what tickets they have been allocated through a lottery system.

Organizers extended the application period by 12 hours, citing high demand.

Overseas residents will have to wait until June 15 when tickets are put on sale by special distributors in each country — known as Authorized Ticket Resellers.

Organizers declined to say how many tickets have been applied for through the on-line system. They say only that 7.5 million "ID registrations" have been recorded, which then allows people to apply and enter the lottery.

Organizers estimate 7.8 million tickets will be available, with 20 to 30% dedicated to sales outside Japan.
