Tokyo unveils heat-busting stadium, 7 months before Olympics

Tokyo formally unveiled its 60,000-seater main Olympic Stadium Sunday, more than seven months before the 2020 Opening Ceremony -- with a host of special features to beat the feared heat.

Built on the site of the former national stadium used for the 1964 Tokyo Olympics, it has five floors above ground and two below, with greenery planted on the decks to provide shade from the scorching summer sun.

The eaves around the outer perimeter keep out sunlight and rain and will help channel breeze into the stadium. There are also eight mist spraying facilities, 185 fans and 16 air-conditioned lounges.

Opening the facility, Prime Minister Shinzo Abe hailed its "top-level universal design" and "harmony with its surrounding environment."
