Greetings from the President

I was appointed as the representative director in 2008. I will continue the will of my predecessor and further enhance the services we can provide to you.

Even though construction materials and methods may change, our passion for building houses will never change.
Our goal is to create a building that can adapt to changes in the community and lifestyle, and that can circulate, so that we can build a highly durable home and remodel it when the time comes. We do not do construction based on price alone.

We cannot afford to cut back on the number of people and building materials needed to carry out responsible and high quality construction. We will work together to ensure that the people who live in and invite to homes have a comfortable life. We have a lot of experience in doing various kinds of work related to houses.

Please feel free to contact us if you have any questions, even if it is a small matter, or if you want to repair somewhere, but you don’t have any idea where to ask for.

Director Keita Tanaka
