History

Nikken Sekkei dates its origins back to 1900, as an offspring of Sumitomo Corporation. Under the name of Sumitomo Temporary Architecture Department, it was founded in response to Sumitomo's need to establish a headquarters. The company established its independence from the Sumitomo Corporation in the 1950s under the name Nikken Sekkei Komu Co. Ltd. As a private practice since 1970, Nikken Sekkei has maintained its In-house Shareholder Corporate System and is partly owned by its employees.

Nikken Sekkei together with Nikken Sekkei Research Institute (NSRI), Hokkaido Nikken Sekkei, Nikken Sekkei Civil Engineering (NSC), Nikken Housing System Ltd (NHS), Nikken Space Design (NSD), Nikken Sekkei Construction Management (NCM) forms the Nikken Group.
