Company history

Sumitomo Realty & Development was founded on December 1, 1949, as Izumi Real Estate Co., Ltd., taking over Sumitomo Honsha’s real-estate business. It adopted its current name in 1957 and merged with the former Sumitomo zaibatsu holding company in 1963. The company expanded into Osaka and condominium sales in 1964, and was listed on the Tokyo and Osaka stock exchanges in 1970.[9][37]

The company’s development of major Tokyo properties included Shinjuku Sumitomo Building, completed in 1974, and Shinjuku NS Building, completed in 1982. In the 1990s, it expanded into custom homes and remodeling, and in 1999 entered real-estate joint-investment funds and commercial-property securitization. Its subsequent landmark projects included Izumi Garden Tower (2002), Shinjuku Grand Tower (2011), Tokyo Nihombashi Tower (2015) and Roppongi Grand Tower (2016).[9][37]
