Greeting from CEO

I started my career as Construction Engineer at Site and have been consistently engaged in construction-related work since then. The sound of construction, the feeling of tension, and the appearance of the people who work there are important treasures in my life.

Although it has just been transformed from an one-person business, we’re full with a strong desire to contribute to the construction industry by our own effort.

Having been worked on domestic and overseas construction projects, every time I see a building that has faced various difficulties and built up with the wisdom and effort of the people involved, I feel awe of construction industry.

We will take the advanced technology of the world into the construction technology and skill that Japan is proud of, and we will endeavor to help everyone in the construction industry.

We will continue to pursue the concept of Construction x Technology = ∞. We look forward for your continued support and patronage in the future.
