ITEC Co., Ltd.
CEO Masayasu Iida

Japan, where I was born and raised, has wonderful nature and enriches my life in each season. There are also abundant and prosperous creatures in the frigid regions of Antarctica and the Arctic. We are now required to build a recycling-oriented society that can maintain the prosperity of today that humankind has built while protecting this wonderful environment of the earth, and continue and develop toward the future. I think that the key word of the energy source necessary for building this recycling-oriented society is "sun, water, air", and the key word of technological development is "advanced supercritical technologies".
We have been creating new materials and developing equipment using water and carbon dioxide as reaction fields in supercritical systems that utilize high-temperature and high-pressure technology. This process was started through industry-academia collaboration, and 10 years have already passed, and today we are finally in the stage of practical application. Energy-related and environment-related businesses will continue to grow with the times. We will accelerate the practical application of these functional nanoparticle synthesis technologies and do our best to help society by providing next-generation advanced materials necessary for building a recycling-oriented society. We look forward to your continued guidance and support.

Please do not hesitate to give us your opinions, impressions, or anything about our company.
We'll be expecting you.
