Company Philosophy

Sengi Kori

The characters above are pronounced "Sengi Kori" and mean that those who put virtue first, and profit last, will prosper. This is a teaching of Xun Zi, a disciple of Confucius. Taking it to heart, we at BioRangers have since the very beginning of our company believed that putting the interests of customers and all other stakeholders first, and sincerely addressing their concerns, will ultimately contribute to our own development as a company. "Sengi Kori" captures perfectly the character of the organization we aim to be. It is a pure expression of the convictions and philosophy we practice in our business.

Message from the President

BioRangers, Inc. Representative Director and President Masakazu Kono

Our goal is to deliver services that give rise to new value.

When BioRangers was established in 1998, we became the first company in Japan to use microorganisms to remediate contaminated soil and groundwater. Since then, the perceptive understanding and cooperation of a great many companies has enabled us to complete over 200 remediation projects. Going forward, our goal will continue to be to perform highly effective, economical, and environmentally conscious remediation services.
