There’s so much more to the Japan Pavilion! So in this post we’ve taken a deeper look. Check out our tips on how to get the most out of the experience, and then go visit the Japan Pavilion!

Rotate. Circulate. Feel the cycle of life. Experience “circulation” at the Japan Pavilion!

The Japan Pavilion is the largest at this year’s Expo. Its vast grounds (approximately 12,950 m²) are large enough to fit a baseball field, and the theme of the pavilion, “Between Lives,” is present throughout the space.

What does “Between Lives” mean?

All living things, as well as the things and systems created by humans, are imbued with life. When each one fulfills its role, it is passed on to something else, changing form and taking on a new role… The Japan Pavilion focuses on this cycle of life. Inside and outside the pavilion, each visitor is also part of this cycle. Through viewing the exhibits, visitors become aware of their own links to the various activities of life.

Expressing the Cycle of Life Through Architecture

What really catches the eye about the architecture is the wooden planks. Made from thinned wood, they are called CLT (cross-laminated timber), and 560 pieces are used in 280 sets for the interior and exterior walls. By arranging them diagonally in a circular pattern, they embody the “relay of life” and “circulation of life.” As the building is planned to be reused after the Expo is over, the pavilion’s architecture was designed to avoid damaging the planks as much as possible and to make dismantling easier.

The gaps between the boards allow the presence of people, sounds, and light to be felt from both inside and outside the building.
The benches placed around the perimeter of the pavilion are also made from CLT. The warmth of the domestic cedar is very comfortable!

Introducing the Three Areas of the Japan Pavilion

The Japan Pavilion is made up of three areas that form a large circle. We’ve picked out some of the highlights of the pavilion, which is packed with the latest technology, the mysteries of the universe, and rediscovering the culture that Japan has cultivated, all of which are based on the idea of ​​learning from the past and creating something new.

Maps of the pavilion can be found in multiple locations around the perimeter.
The hourglasses that greet visitors at the entrance to each area mark the passage of time in each individual’s unique life.

Plant Area: From Garbage to Water

What we want you to focus on in this area is the workings of microorganisms.

The popular bear-shaped toy, BE@RBRICK, expresses the idea that the food waste collected from the Expo site is not something that can be thrown away or its final form.

After experiencing the process of how waste is transformed into water and energy at the biogas plant attached to the Japan Pavilion, you will emerge at the water basin located in the heart of the Japan Pavilion. What’s more, one of the world’s largest Mars rocks awaits you. Be sure to pick up a “Mars Rock Viewing Certificate”* at the exit of the area as a memento of your visit! *Certificates will be distributed while supplies last.

If you look closely at the trash on the conveyor belt, you can see a certain popular character!

Farm Area: From Water to Materials

Modern society faces the challenges of dependence on fossil resources and food shortages. Algae is gaining attention as a potential solution to these issues. The exhibit explores the diverse possibilities of algae. Don’t miss the popular Hello Kitty display! 32 different versions of Hello Kitty represent both seaweed familiar in Japan, such as wakame and hijiki, and species that can only be seen under a microscope. Finding your favorite Hello Kitty will make you feel closer to algae♪

Factory Area: From Materials to Products

The theme of this area is “things” and “manufacturing.”

As you walk through the area, you’ll come across a corner dedicated to Japanese manufacturing, which has a long history of focusing on “soft” production. Doraemon (one of Japan’s most treasured anime characters) will be your guide to the area, providing laid-back and humorous explanations of the exhibits. You can find hints for a sustainable society in the exhibits, which are filled with the mottainai spirit, a traditional way of thinking that values cherishing things.

Also, don’t miss the ephemeral art created by water dripping onto a diatomaceous earth canvas!

The Biogas Plant That Generates Energy for the Japan Pavilion

The Japan Pavilion is also known as the “Garbage-Eating Japan Pavilion” and the “Living Pavilion.” The reason for this is its biogas plant. Food waste collected from within the Expo site is broken down using the power of microorganisms and converted into water for the basin and biogas. This biogas is used to generate electricity, which contributes to the Japan Pavilion’s electricity supply.

The Biogas Plant is normally closed to the public, but did you know that tours* are available? Don’t miss this chance to see the equipment up close while listening to a guided tour by the plant’s architect!

*To participate in a tour, you must purchase an admission ticket and make a reservation in advance via the reservation website. Please check the reservation website for availability.

The plant attached to the Japan Pavilion generates biogas electricity and has a maximum processing capacity of 1 ton per day!
