Niterra is a silver partner in the Future Society
Showcase Project, “Future Life Expo: Future City”
at Expo 2025 Osaka, Kansai, Japan

We aim to continue contributing to society and the future by not only leveraging our core technology of "ceramics" cultivated over more than 80 years but also advancing business innovation and portfolio transformation to address global environmental changes and complex social issues.

On April 1, 2023, we changed our English company name from NGK Spark Plug to Niterra and formed the Niterra Group.
The new group name incorporates our organization's desire to become a company that contributes to a sustainable society and brightens the earth.
This aligns with the Expo's goal of finding solutions to global challenges and inspiring hope for the future, as expressed through their theme "Designing a Future Society for Our Lives.“

In the Future Society Showcase project, "Future Life Expo: Future City" at the Expo 2025 Osaka, Kansai, Japan, we will dissimilate “Niterra’s challenging spirit and transformative DNA” and “Passion put into Niterra” to the world, contributing to the realization of a bright future society.

Exhibition Theme

“Brightening the Future of the Earth” with the Power of “Water” and “Air”

Niterra Co., Ltd.'s initiative for a bright future is its “Autonomous Portable Circulation Technology.” It envisions a future society where devices make their own decisions, delivering sustainable resources and energy anywhere, to anyone, when needed.
At the exhibition, a navigator will introduce the water and air circulation system called “CyclusNiterrium.” In addition, through our latest aerial sensory device equipped with an ultrasonic generator, you can interact with the characters known as “Niteon” who embody this circulation technology. Finally, we invite you to a virtual venue depicting a future where the Niteon play an active role.

What Is “Niteon”?

Niteon is an original character created to make Earth shine brighter, embodying our company’s circulation technology. For example, Suisui breaks down water to produce green hydrogen. Many other Niteons with various technologies will also make an appearance. Visit and find it!

Virtual Expo

Niterra will showcase an individual room at the Virtual Expo. It is a world where Niteon, endowed with circulation technology, comes to life. The experience comprises Niteon’s demonstration facility, “Niterium,” and its research facility, “Niteon Lab.” There is no predetermined sequence—you are free to explore by undertaking missions or engaging in biological investigations of Niteon as you wish. You can learn about circulation technology while having fun.

Scheduled for release in April 2025!

Circulation Performance by Water and Air

Circulation begins with the Water Symbol "CyclusAqua.“ Through our circulation technology, “water and air” change their shapes and forms, The navigator and the images work in unison to show how the future of the earth is brightened by the transformation of “water and air” through our circulation technology.

Portable Circulation Device for The Future

Using our future circulation device, “water and air” will undergo transformation. In doing so, they will assume new roles and contribute to a circular society.

SOEC
A device that electrolyzes water (H2O) to produce hydrogen (H2).
Methanation
A device that converts hydrogen (H2) and carbon dioxide (CO2) into methane (CH4).
SOFC
A device that chemically reacts methane (CH4) with oxygen (O2) to generate electricity and water (H2O).

Aerial Sense Device

Using ultrasonic technology, this device enables you to interact directly with images floating in mid-air. You can touch “Niteon” with your bare hands and experience the tactile sensations associated with each character’s unique abilities. Moreover, thanks to ultrasonic technology, you can also enjoy three-dimensional sound that is audible only to you. The ultrasonic generator used in the Aerial Sense Device incorporates Utilizing Lead-free Piezoelectric Ceramics—an environmentally friendly material developed by our company.
※Lead is a substance regulated under the RoHS Directive, and to reduce environmental impact, the use of lead-free piezoelectric materials is encouraged.

Area① Niterium

This is Niteon's demonstration facility, developed by the Niterra Group. Become a Niteon researcher and observe Niteon in action. At Niterium, missions have been prepared for you. We encourage you to take on the challenge.

Area② Niteon Lab

This is a facility where research and development on Niteon takes place daily. Inside the Niteon laboratory, the production machine enables you to create Niteon. By completing missions in Niterium, you’ll receive clues to its creation. Various exhibits also showcase materials related to “Niteon” and “Niterium.”
