Hiroshima Motomachi Aquarium, newly opened in Hiroshima Prefecture, has an displays concept called "A Museum of Water and Life." Each of its eight stages conveys a different message, displays the underwater world and the activities of living creatures, expressing the power and fragility of life. Each stage connects to the others, showcasing the fascinating creatures living in diverse environments and illustrating the facility's theme, "The Stage of Life." "Welcome" offers a fantastical portrayal of the beginning of life, while "Forest" conveys the changing seasons and the vitality of forests. "White" depicts a colorless world and the brilliance of life, while "Marine Note" and "Coral" introduce the diverse ecosystems of the ocean and the colors of coral reefs. "Flowers, Birds, Wind, and Moon of the Sea" expresses the mystery and beauty of the underwater world, while "Zipangu" depicts traditional Japanese beauty and the elegance of goldfish. Finally, "Message" uses a clock that tells the time of extinction and evolution to emphasize the fragility of life and our responsibility to the future, evoking a moving and resonant experience. To convey a deeper understanding of the concept and to convey emotion, we have incorporated immersive experiences and interactive displays that stimulate the five senses.
