Its theme highlighted the relationship between human activities and nature with the purpose of rethinking the use of technologies and lifestyles as well as to exchange ideas on the preservation of ecosystems. Presenting prototypes and making demonstrations, the Expo contributed to the development of new strategies, methods, techniques and technologies.
The Nakagute area hosted the international and corporate pavilions. Here, visitors could learn about the theme and (re) discover the pleasure of being in contact with nature.The second zone, Seto, located in the Kaisho Forest, was dedicated to the Satoyama culture, which is an example of the Japanese tradition of living in harmony with nature. It is in this area that were located the Aichi Pavilion, the Japan Pavilion and the Citizens' Pavilion.
Visitors to the Expo were able to experience, one step ahead of the rest of the world, new green technologies and environnemental solutions. For example, plastic waste and wood rests were used in the construction of buildings and biodegradable-plastics in the fabrication of over 20 million plates and cutlery for restaurants and catering. The Japan Pavilion used only renewable technologies to meet its energy needs. The Intelligent Multimode Transit System (IMTS) was used as a mode of transport within the Nagakute Area, and the fuel cell hybrid buses linked the Nagakute and Seto Areas.
Thanks to different pavilions and attractions, the Aichi Expo highlighted the relationship between humans, nature and technology.In the Earth Tower visitors discovered the wonders of light, wind and water. When they entered the 40-metre tower and turned towards the sky, they saw a ball of rising light about 36 meters in diameter. The external walls shimmered with flowing water, which in turn created the sound of the wind. This pavilion recalled the beauty and power of nature.The theme pavilion the Bio-Lung impressed the visitors with its 150 m long and 15 m high "green wall". It was fully covered by a variety of flowers and plants and represented a means of offsetting the urban heat-island effect. The JAMA Wonder Wheel Pavilion was recognizable by a large Ferris wheel that emerged from the pavilion. It allowed visitors to have, from its top, an overview of the Expo site. The pavilion was made of recyclable materials, which after the end of the event were reused for the construction of another building.
In July 2006, a part of the Nagakute area became the Expo Memorial Park. It is here that the house of Satsuki and Mei, two protagonists of the famous animated film "My Neighbour Totoro", was created. In addition, a children's activity centre and a Japanese Park were built.
In September 2006, the Aichi Kaisho Forest Centre opened in the former Seto Pavilion (Seto area). The centre was created to preserve the Kaisho Forest and create a gathering place for education.
In March 2007, a museum dedicated to the Expo, an indoor swimming pool and an ice rink were also inaugurated.
