The concept of Eco-Breathing Architecture—a structure that breathes like a living organism—was adopted in the construction of the Japan Pavilion, and the building plan was based on the following policies.
structure incorporating environmental technology

- The Japan Pavilion combines traditional Japanese knowledge for living in harmony with the environment, such as ennoshita (the utility space under verandas) and uchimizu(the sprinkling of water by hands to reduce heat) with the latest environmental control and materials technology.
- Vertical hollows are strategically placed in the pavilion to make use of ancient Japanese knowledge for maximum incorporation of the power of nature, such as bringing in sunlight, using stored rainwater, and circulating air naturally.
- A cool environment is created with the generation of mist in areas where visitors will wait.
structure with dynamic spaces

- The Japan Pavilion is designed so that major spaces within the Pavilion are covered with large roofs, creating a distinct exterior that appears to be alive.
- The base color for the exterior of the Japan Pavilion is a reddish violet. This color is viewed as a natural color that arises from the harmony of red, symbolizing the sun, and blue, symbolizing water. The outer covering changes to highlight and complement changes in daylight or at night, so that the movement of nature can be felt.
