The last big batch of tickets for the Rugby World Cup in Japan can be purchased online starting Saturday, with organizers making a last-minute push in their bid to completely fill the stadiums.

Online sales for some 250,000 tickets open at 6 p.m. on Saturday and will run on a first-come, first-served basis. The 20-nation tournament will see 48 matches played at 12 venues between Sept. 20 and Nov. 2.

About 1.44 million, or 80 percent, of the 1.8 million available tickets have already been sold.

In a digital marketing campaign to promote the sport, organizers have created "meet the team" and "players to watch" pages on, the tournament's official website.

"There are highlight points in each game and they're all going to be interesting," said chief ticketing and marketing officer Shoichi Morishige, the chief ticketing and marketing officer.

Former Japan head coach and current England boss Eddie Jones is among those who introduce Rugby World Cup host cities in a video posted on, a special site created by the Japan National Tourism Organization, which is linked to the ticketing site.
