It is said that there is an island on which all living creatures hold special festival to celebrate a rainbow that occurs in the middle of the night.

It isn’t just celebrated by animals. The insects, plants, and even creatures long extinct are said to appear as part of the festivities.

A child named Ao stumbles upon one of these rare rainbows.

Before Ao’s eyes, something strange begins to happen…


A Spectacle
of Air
and Water

Introducing the Moonbow Festival, a spectacular immersive show based around the themes of air and water, scheduled to be held at Expo 2025 at the Water Plaza, a symbolic area of the World Expo.

The show will feature roughly 300 fountains and water screen projection in combination with music, lasers, fire and other dazzling elements, all coming together to form an innovative and multimedia entertainment experience on a grand scale.



From Suntory and Daikin.


Air and water.

They have been on this planet for billions of years,
and to this day they continue to change form
while flowing through the sky, the ocean, the land,
and all the living things that have roamed the earth.

It is from them that every living thing on the planet is born, grows strong, and flourishes.

This made us think.

“Air and water contain wisdom.”

There must be something that these elements, which have seen everything that has come to pass on earth, can teach us about the future.


We created a show based on this concept.

Expo Osaka 2025 will be an event where people from all over the world can share their ideas about creating a society where life flourishes.

Our production will be another participant to this incredible event.
We hope that together we can enjoy new experiences and encounter new emotions that help lead us to a better tomorrow.

Air and water.

They have been on this planet for billions of years,
Flowing through the sky, the ocean, the land, and all the living things that have roamed the earth.

That glass of water you drank today might have quenched the thirst of a triceratops.

The air you breathe today could be the air in the sky of the distant future.

Air and water have wisdom.
The wisdom to guide us to a better to tomorrow.
The wisdom to show us what we should do today.
