An easy-to-understand guide to MIURA.

Tamotsu Miura had a goal for manufacturing
when he first established this company 60 years ago;
"We will make the boiler of the world's best price and quality ever!"

We at MIURA hope to be the best partner for energy, water,
and the environment, trusted by customers around the world.

For the earth, the future,
and to keep smiles on the faces of children forever.

We will contribute to creating a society
that is environmentally friendly and ways of living

This is the MIURA Group Mission.
We at MIURA see it as our duty to work from this mission to act as the best partner to the customers who trust us around the world, aiding in energy conservation and environmental protection, and contributing to the creation of a sustainable society through our business activities.

Energy, water, and the environment×SUSTAINABLE DEVELOPMENT GOALS

Expanding the hydrogen business
for the future

In the fight against global warming that is a shared cause for the entire world, MIURA has taken on the challenge of creating a carbon-free hydrogen society.

We are now working to commercialize ideas for new energy applications, developing products such as solid oxide fuel cell systems, hydrogen-fired boilers, and hydrogen production equipment.

the low-temperature sterilization technology that will change the world

We support society with the latest sterilization technologies, including those that control the spread of infectious diseases to allow people to travel the world with peace of mind, reproductive and regenerative treatments to improve precision in tasks such as culturing by suppressing the growth of abnormal cells, area decontamination to reduce the amount of residual chlorine present while improving sterilization effects, and control of resistant bacteria to eliminate the problem of drug resistance that makes medication less effective.

Protecting marine ecosystems
Ballast water management system

The sea, source of all life.
Cargo ships around the world use the sea to carry mountains of goods.
Cargo ships not laden with freight take on seawater as ballast, which they then expel into the ocean when they arrive at their destination and load on their cargo.

We know that the organisms mixed in with the ballast water taken on have a negative effect on the marine ecosystems in the areas where they are dumped.
MIURA's ballast water management system eliminates organisms contained in ballast water, helping to address marine environmental issues.

Total solutions deliver further energy savings to solve the problems our customers face

While initiatives for new energy are important, energy conservation that can be achieved now is even more so.
MIURA's total solutions offer further energy savings for those of our customers who are endeavoring to address environmental issues.
Undertaking a total review of utility equipment, transport lines, production facilities, and energy management allows us to maximize potential for energy conservation.

MIURA's Combined Strengths

Since our founding in 1959, MIURA has made the most of our know-how in boiler development and production to grow a wide variety of businesses.
Currently MIURA is leveraging its strengths in a broad range of domains such as air and electric power as well as energy, water, and the environment. As our businesses grow, so does the scope of our maintenance services.
Even though we may be active in a broader range of business domains, our desire to contribute to our customers through energy conservation and environmental protection remains unchanged.
