海と話そう。

A Conversation
with the Seas

This planet on which we live contains sacred
mysteries that still lie beyond the grasp of even the
most advanced science: the cosmos, Earth, all living
things, and the oceans that bring forth an endless
chain of life. Here, you will be able to connect with
Earth, our water planet. The BLUE OCEAN DOME
installation showcases ultrahydrophobicity*, offering
a whole new way to experience water. The oceans
hold about 97% of Earth’s water. This colossal
spherical theater depicts little-known aspects of the
seas, as well as the true state of plastic pollution. How
might this profound encounter with Earth reshape
our vision of the future?

PAVILION

The BLUE OCEAN DOME theme is “Revitalization of the Ocean.” Declining reef habitats, rising sea temperatures, catastrophic effects of global warming, and plastic pollution are just some of the crises impacting our oceans. Painstakingly portraying issues and challenges that face our Blue Planet, we reassess these relationships in the context of big concepts—the earth, the universe, life, and environment—in a manner that dramatically awakens eco-consciousness.

Tasting Exhibit: Purify: A Primordial Saltwater Tonic

At the café in Dome C, you can reorient your senses with a spirit-reset solution created by culinary expert Yoshiharu Doi. It is a one-cup expression of the bounty of nature, untouched by human interference. This invigorating beverage blends mountain spring water with pure sea salt derived from evaporated seawater, resulting in a drink that evokes a sense of natural purity.

Comment

Inheriting the philosophy of the “Osaka Blue Ocean Vision” achieved by the G20 in 2019, ZERI Japan will present the Blue Ocean Dome as a private pavilion, aiming to ① prevent plastic marine pollution, ② develop a sustainable marine industry, and ③ promote the understanding of ocean climate change, thinking and acting together with people and companies from all over the world to find solutions to these issues.
During the Expo, this movement and its exhibitions will not be confined to the venue, as we plan various events inside and outside of it to communicate our plans and activities to help solve the pollution challenge. We are looking forward to the participation of people, companies, and organizations from all over the world.

Comment

Historically, world expo pavilion architecture has essentially been a testing ground for new architectural ideas, structures, and materials. Unfortunately, in recent years, most pavilions have been a “play of shapes,” showcasing architectural designs and forms that depend on computer technology. BLUE OCEAN DOME introduces novel and unprecedented materials and structures. It serves as a platform for Japan to share cutting-edge technology and integrate it into society’s foundation. By using three materials that are strong, light and highly recyclable–paper, bamboo, and CFRP [Carbon Fiber Reinforced Polymers]–we have reduced the building’s weight and constructed it without driving a single pile. We leveraged the construction requirements of exposition pavilions–temporary construction and limited timelines–to create innovative architectural solutions. The pavilion significantly minimizes construction waste and can be easily dismantled, relocated, and reused.

Pavilion Producer

Kenya Hara

Kenya Hara provides multifaceted design direction utilizing Japanese tradition and aesthetics as future resources. He emphasizes the design of both objects and experiences, and has built a strong international reputation.

Comment

Astronauts describe a profound shift in perspective when they view Earth from space. As they gaze at our life-giving blue planet suspended in the endless black void of the universe, the staggering distances between stars underscore the miraculous nature of Earth’s very existence. Seeing Earth as a tiny sphere from this great distance fills them with an overwhelming longing to return. If we could give you a similar view of Earth, we might spark the same profound shift in consciousness that astronauts feel. The theme of this pavilion is “Reviving the Ocean.” While vividly depicting the problems facing our planet–CO2 fixation, marine resource conservation and plastic pollution–we hope to dramatically awaken people to environmental morality by reexamining the relationships between these elements from the perspective of larger concepts, like Earth, Universe, Life, and Environment.
