Gaia Hypothesis

The above concepts of Kaiyukan follow a part of Gaia Hypothesis advocated by Dr.James Lovelock. This hypothesis includes "a theory of the Earth as a living organism - where the evolution of the species and their material environment are tightly coupled but still evolve by natural selctions -.(THE AGES OF GAIA, Preface xix, by James Lovelock)"
Design of the Aquarium
Kaiyukan is a vertically long aquarium having each exhibit in a spiral manner from the top. While climbing down the building from the 8th through the 3rd floor, visitors enjoy the tour of the Pacific Ocean based on the above theme.
