"I want to make good things."
- Carrying on the thoughts of developer Toichiro Koyama
In 1988, at the age of 54, he founded N.E.T. Corporation and used his knowledge of textiles to invent the Biofringe (a high-performance microbial retention material). Since he himself had a deep respect for the natural environment, he aimed to create a healthy water treatment environment for microorganisms, and conducted a series of analyses and research to "create a good product" and "accumulate as much experimental data as possible. As a result, we have surpassed the limits of conventional contact materials and have earned a high reputation in the water treatment industry for more than 30 years, including engineering design and proposals for treatment in various fields.

My father, who was a meticulous person, left a long document on the history of the company called "The History of N.E.T.", and he ended it with the sentence, "Microorganisms do not betray. As a person who works with plants for a living, I have actually had the experience of strongly remembering that "plants do not betray. I felt as if I had received what my father wanted to convey in that short sentence, and it strengthened my resolve to take on the next generation. I am determined to carry on the passion of the developer and respond to your requests, and I look forward to your continued guidance and encouragement.
