Characteristic Strengths of Sanko Estate

Three Characteristic Strengths of Sanko Estate

Proactive action

Sanko Estate conducts leasing brokerage for approximately 1,600 spaces totaling as much as 200,000 tsubo (approx. 661,000m2 or 7,116,000ft2) annually throughout Japan. The area is estimated to be equivalent to 10% of the total office area contracted for leases annually in the major cities of Japan.

This achievement is a result of the efforts of our nearly 200 leasing brokerage staff nationwide providing clients with the best services through quick proactive action based on our deep knowledge of the properties. These efforts will continue going forward.


Sanko Estate introduced computer systems 30 years ago, ahead of anyone in the industry, and has accumulated information on approximately 100,000 office buildings throughout Japan. We keep the information updated, which includes “exclusive information” as well as publicized information. Based on the latest available property information, we propose office spaces that match the requests of our clients.


Sanko Estate negotiates with landlords in an effort to allow our clients to conclude contracts for the office spaces they favor, with terms and conditions that are reasonable and acceptable. With our strong presence in the office leasing market, we receive repeat business from many clients.
