Japan will highlight the role of advanced ecological technology in helping humans achieve a more comfortable life and confidence in the future with its huge "breathing organism" pavilion at World Expo 2010.

The country's exhibit will feature a theme on the harmony between the human heart and technology.

The theme is an extension of the Aichi Expo 2005 theme "Nature's Wisdom" and also an interpretation of the "Better City, Better Life" Shanghai Expo theme.
Japan Pavilion has secured a 6,000-square-meter plot at the Expo site. The 24-meter-high pavilion is the largest the country has ever built for a World Expo. It is also one of the largest pavilions at Expo 2010.

The pavilion will be divided into past, present and future exhibits.
The country's semi-circular pavilion will make efficient use of natural resources with solar energy collection batteries and a double-layer membrane that can filter sunshine to coincide with its interpretation of how technology can better our lives.

Visitors will be able to experience some Chinese elements at Japan Pavilion, which will involve Chinese characters and traditional Chinese architectural styles. The history of Japanese diplomatic envoys visiting China will also be part of the exhibit.

Some intelligent robots will also be a part of Japan Pavilion, but the official declined to reveal more information in order to keep the exhibit a surprise.

Japan is a member of the International Expositions Bureau. It has hosted five World Expos including the Osaka Expo in 1970, which set an Expo record of more than 64 million visitors.
