Origin of Caetus

Caetus Technologyロゴ

"Caetus" was coined from two Latin words: "Caelum", meaning the heavens or society, and "Ventus", meaning the wind.
Our name signifies our desire to create technology that, like the wind, brings fresh air into society and people’s lives.


Caetus Technology Co., Ltd. works with experts in various fields to send out new products and services into the world. To bring the benefits of technological innovation to consumers' lives quicker and with added safety, we adopt a solutions-oriented approach that goes beyond the framework of conventional services and products.
We started off by initiating a project to create functional cosmetics for professionals who suffer from rough skin as a result of the overuse of their hands, based on the concept of creating an artificial “third skin” to cover the dermis and epidermis. In our future cosmetics projects, we will continue to send out sophisticated products and services into the world while pursuing reasonable functionality and simple solutions with nothing excessive added. And we have also launched a development project for apps which propose totally new forms of self-medical care and portable medical care.
Please expect to see these and many more exciting products and services from Caetus Technology in the future.
