The remarkable advancements in modern science and technology, as well as architectural technology, which have brought us significant economic development and a convenient lifestyle, have also come at a great cost. In the pursuit of functionality, these advancements have led to the destruction of the health of the people living there and the irreplaceable natural environment. Faced with this issue that will impact future generations, people are now entering a turning point where they must consider how to harmonize and coexist with the Earth. At Okubo Equipment Industry, which believes that the foundation of a comfortable living space lies in clean air and clean water, we are reflecting on the role we can play under the theme of "Creating a people-friendly comfortable space while leaving a rich natural environment for the future." We aim to utilize the technologies and know-how we have cultivated over many years for the benefit of people and the Earth, both now and for future generations.
