Company information
We are seriously considering and materializing the creation of a "circular society." That is our mission. Nature constantly changes its form and circulates while transforming. I find the mechanism of that circulation, which transcends human wisdom, to be very beautiful. The universe, the Earth, the human body, and our society are all part of nature. We aim to realize a better circular society by taking nature as our model.
