Tokyo's New National Stadium, the main venue for next year's Olympics and Paralympics, has been shown to media ahead of its planned completion this year.
The stadium is about 90 percent finished. It's scheduled to be completed at the end of November.
Journalists were allowed inside on Wednesday, almost a year before the games' opening.
The stadium's three-tiered stands are white, green and brown, and its roof, completed in May, is made from trees grown in Japan.
About 45,000 of its 60,000 seats have been installed, as well as 185 blowers for cooling down spectators.
Test images were displayed on two screens measuring more than 30 meters wide and nine meters high.
The stadium's pedestrian deck features trees from Japan's 47 prefectures.
About 2,400 people are working on the arena. They are to start laying the turf for its field this month, and begin work on its tracks next month.
A public opening event is scheduled for late December.
