Overview
Business One Holdings Co., Ltd. (ビジネス・ワンホールディングス株式会社) is a Japanese holding company headquartered in Chuo-ku, Fukuoka City, Fukuoka Prefecture. It is listed on the Fukuoka Stock Exchange Q-Board market under securities code 4827. The group traces its origins to 1984, when it was founded in Nagasaki City, Nagasaki Prefecture, as a building CAD system development group. It was incorporated as Business One Co., Ltd. (株式会社ビジネス・ワン) in 1987, and later reorganized into a holding company structure in 2008, changing its trade name to Business One Holdings and relocating its head office to Fukuoka City. The group operates across several business domains: real estate, real estate development, condominium management, rental management, finance, software, and health businesses. Its subsidiaries include Business One Co., Ltd. (software), Business One Facilities Co., Ltd. (condominium management), Business One Finance Co., Ltd. (finance), Cosmolight Co., Ltd. (real estate), Business One Rental Management Co., Ltd. (real estate leasing and consulting), Across Co., Ltd. (real estate), and others. The group also operates a furniture and home appliance rental business through Tebra de Dotcom Co., Ltd. Historically, the company's software business developed and sold packaged software specialized for specific industries, including document creation and management systems, estimation systems for electrical, plumbing, and fire protection contractors, and construction/reform estimation systems. Its major clients included major multifunction printer manufacturers such as Ricoh, Otsuka Shokai, and Canon Marketing Japan. In 2010, the company's stock industry classification changed from "Information & Communication" to "Real Estate," reflecting the growing weight of its real estate operations. The group's management philosophy emphasizes creating new business models unfettered by existing frameworks, and it aims to strengthen synergies among its eight group companies, enhance corporate value, and return profits to all stakeholders. It continues to position Fukuoka as its base of operations while expanding its business portfolio.
