Thinking about the furniture is thinking about the family. In the same way, choosing the furniture with thinking about the family is thinking about the way of living. We designed "Edo-ma" as a module, which is one of the standard dimensions of living in Japan. Furniture neatly fits into limited-Japanese living space. Furthermore, sense of unity and comfortable living space is born. There is tense atmosphere and beautiful layout can be realized. To suit your life style, to match the growth of the family, you can enjoy coordinated freely. That is the "source" brand. As you become ” source” of life to create a smile of family, We will continue to create "source".
