LifeBusiness interior design

L&B is a design company that collaborates with businesses to solve challenges through the power of design. We don’t just pursue aesthetics; we are involved in the entire process—from business strategy, design, planning, and execution, to consulting related to design. If you have any concerns, please feel free to consult with us. We are confident that we can be of help.

We handle around 120 spaces annually, designing and managing everything from private residences, retail stores, and show windows, to offices, RC (reinforced concrete) constructions, and wooden structures across Japan. Since our business started with interior design, we can provide proposals for every detail, including fine furnishings. We also specialize in custom furniture and unique construction methods.

Building trust has always been our priority, and we have continued to receive work solely through referrals.
With a small team of experts, we emphasize doing careful, high-quality work. We take full responsibility and create spaces that fully satisfy our clients.

This translation keeps the original nuances and professionalism while maintaining a clear structure in English. If you have any further questions or require adjustments, feel free to ask!

Representative Director

Takeshi Ue上 岳史

Graduated from Sophia University. While still a student, he founded Alpha Group Co., Ltd., which was listed on the JASDAQ stock exchange 10 years later. He managed the company as a listed company with sales of 30 billion yen for 20 years. After that, he undertook management buyout of education and welfare-related businesses, and once again attempted to start a business as a social entrepreneur. He felt that the system to support the social participation of people with developmental disabilities in Japan was insufficient, so in 2014 he founded Happy Terrace Co., Ltd. (now Dekoboko Base Co., Ltd.), a welfare service company specializing in developmental disabilities, and became its representative director. The company has 232 locations across Japan. He entered the disability welfare business as a corporation and became a pioneer in the industrial development of the welfare field, bringing about social change. In addition to being a founder, he also served as an outside director of two listed companies in Japan for a total of 12 years. He has now moved his base of operations to Silicon Valley in the United States.
