Becoming a shining power for the earth.

Effective April 1, 2023,
our English company name has changed to "Niterra Co., Ltd."As a result, NGK SPARK PLUG Group has become the "Niterra Group".

Concept behind Niterra
Niterra is a word that we have coined that combines "niteo",
which means "shine" in Latin, and "terra", which means "earth".
It expresses the Group's thoughts and stance of becoming
a company that not only contributes to a sustainable society,but also brightens the entire global environment.

Shared Values

Corporate Philosophy
Realize our imagination.
We continue to offer new ideas and new values.

Since its foundation in 1936, the Niterra Group has been exploring the potential of
ceramics and contributing to social development while building trust with our customers,
driven by the mindset of "Participation of all employees" and "Producing quality
products," which are the starting points for all our manufacturing. By doing so, we haveworked to earn the trust of customers in Japan and overseas under the "NGK SPARK
PLUG" company name.
However, in an era when the automotive industry is undergoing a once-in-a-century
transformation, we believe that in order to achieve solutions to social issues faster thanever before, in our various initiatives we need to bring about change that is not simply
an extension of the past.
As part of this effort, we have decided to change our English company name from its
existing name, NGK SPARK PLUG. Our new English company name is Niterra. This is acoined word that combines the Latin words "niteo," (meaning "shine") and "terra"(meaning "earth"). It expresses the Group's desire and commitment to become acompany that brightens the global environment—that truly makes the earth shine.
With technologies that transcend the realm of ceramics, our Group helps realize a better
society by addressing diverse global issues. While maintaining the shared values of the"Nittoku Way" that we have cultivated over the years, each and every Niterra employee
will stay mindful of our call to action—"Change with Will !!"—and will continue to seek
solutions to social issues with the highest aspirations.
We sincerely appreciate your continued, generous support of the Niterra Group.

Exploring needs based on experience.

"If things go well, we may be able to solve the problems ofmany women within a few years." The moment I discovered
the potential for pelvic floor muscle care for postpartum
women, my expectations grew. It was January 2021, 14
years after I joined the company and nine months after I
transferred from the Technology Development Division to
the Marketing Section. Our team was looking for new
business opportunities. Based on my experience of giving
birth and raising children, I came up with the idea of a

Niterra Ventures Company
Medical Business Department
HH (joined in 2007)“pelvic floor muscle exercise support device”. This is truly afemtech ( * ) device, and there is a projec t currently
underway to put it into practical use. My own experiencehas also been useful in the development process. We have
had postpartum women cooperate with our marketing,
and without my experience, it would have been difficult
for me to understand their feelings and circumstances. We
also had female employees from our company act asmonitors, and were able to notice many important issues
from the opinions that were fed back. Once again, I realize
the importance of marketing. There are still many issues tobe addressed in order to make this device easy for ordinary
women to use. However, if we solve these problems andgive shape to this project, I think it will become a strengthof the company in the future. There are unexpected
hardships and problems, but every day that the projecttakes a step for ward is fulfilling and I have felt ver y
rewarded.

Niterra and CCU Contributing to carbon neutrality.

Products that aim to solve social issues invarious business fields

With the urgent need to realize a carbon-neutral society,
Carbon dioxide Capture and Utilization is one technology gaining attention.
This involves the recovery of CO2 emitted from factories and reusing it as a resource.
Niterra is working as a company to realize a carbon-neutral society.

New Products / Services
Creating a future beyond imagination withcross-disciplinary technology
We are committed to confronting the world's challenges andcreating a future beyond human imagination
with products and services in new fields that transcend ceramics technology.

Utilizing all the technological capabilities of Niterra

Various cutting-edge technologies are essential for CCU. The diversity of our technology plays an active role here. For
example, for the recovery and concentration of CO2, we use "oxygen concentrator" technology, which is actively usedin the medical field. For the production of hydrogen, we use the technologies that we have cultivated through thedevelopment of solid electrolytes. The diverse expertise we have accumulated over the years is accelerating therealization of CCU.

Technologies used in CCU

Doctor Link
This new cloud service uses AI and mechanics to remotely check thehealth of vehicles and provide vehicle owners with accurate
maintenance. Diagnosis based on our big data allows us to suggest
the optimal timing and content of maintenance to vehicle owners via
a smartphone application, preventing car troubles before they occur.
In this way, we contribute to the realization of a more convenient lifeof expanded mobility.

Oxygen Enriched Combustion

CO2 recovery/concentration

Hydrogen Production

With the technology cultivated in oxygen
concentrators, it is possible to increase
the oxygen concentration of combustion
support gas and reduce the amount offuel gas used and thus the CO2 emissions.
In addition, CO2 can be easily recoveredby increasing the concentration of CO2 inexhaust gas.

With the technology cultivated in oxygen
concentrators, it is possible to recover theCO2 in the exhaust gas and concentrate it
to a concentration that is easy to use.
We are also considering the liquefactionof highly concentrated CO2 fortransportation.

It is possible to produce hydrogen from electricity andwater in SOEC using ceramics by utilizing thetechnologies cultivated for solid electrolytes. Highly
efficient hydrogen production is possible by combining
waste heat such as from methanation.

value with
“Regional CCUTM”.

"Regional CCU™" is a concept that uses CCU to aim for carbon neutrality throughout an entire
community. Starting with companies that emit CO2, we will circulate the flow of carbon recycling
while making the most of local characteristics. At the same time as reducing CO2 emissions tovirtually zero, we will solve community social issues and revitalize local societies. This will in turn
be connected to the concept of sustainable cities that will be part of the next generation. We
hope to realize such a vision of the future through "Regional CCU™". The target is 2030. We willcontinue to work toward this goal in cooperation with other companies and local governments.

NGK SPARK PLUG (*) was founded in 1936. However, our roots canbe traced back more than 140 years to the Morimura Gumi which
was established in 1876 by Ichizaemon Morimura, the forefather ofthe Morimura Group.
Our founding father Ichizaemon Morimura was an honest andpassionate merchant. Determined to reclaim wealth which had
flowed overseas, Ichizaemon embraced the challenge of foreign trade
for the prosperity of Japan. Eventually, the Morimura Gumi began to
manufacture ceramics and the Morimura Group was born, ultimately
leading to the founding of numerous prominent companies including
Niterra.
