Early Life
Masaaki Arai was born on October 29, 1965. Information on his early life and education is limited. He joined Unihouse Incorporated in 1987.
Rise to Success
In 1997, Masaaki Arai founded Open House Group. Under his leadership as President and CEO, the company focused on providing homes, with the aim of finding houses in Tokyo. The company went public in 2013 and has sold over 60,000 homes in the Tokyo metro area. Arai’s aggressive, unifying style has been compared to the warlords who unified feudal Japan. Open House Group reported $8.6 billion in annual revenue in the fiscal year ended September 2024. The company's success is partly attributed to its unique approach to land acquisition and sales strategies, focusing on customer needs and market demand. In 2025, Open House expanded its operations to the US property market.
Key Business Strategies
Arai's business strategy revolves around acquiring land and building houses, overseeing every step of the process. Open House focuses on land close to railway tracks or of irregular shapes, acquiring them at a lower cost. The company employs young people for land acquisition, increasing the frequency of visits to real estate agents. Open House differentiates itself by catering to specific needs and providing customized solutions, unlike traditional home builders. The company also uses data-driven sales strategies and accepts crypto payments.
Philanthropy
Open House Group is committed to sustainability, with initiatives to address climate change. It signed the "UN Sports for Climate Action Framework" and set goals to reduce greenhouse gas emissions. The company introduced a "CO2-free menu" for customers of its single-family homes, and expanded the supply of "carbon-free clean electricity" in Ota City Sports Park.
