Sumitomo Building

Sumitomo Building is an office building in Kitahama, a commercial district of Osaka, housing corporate workspaces across multiple floors. The structure rises prominently in the downtown area and serves as workspace for various professional organizations and businesses.

The building was completed in 1962 according to designs by architect Masajiro Yamane during a period of intense commercial growth in post-war Japan. Its completion marked an important phase of urban development as Osaka rebuilt economically after the war.

The building reflects corporate design principles of 1960s Japan, showing how major companies thought about workspace and professional identity. Its appearance and internal organization demonstrate the architectural standards that shaped modern office environments of that era.

The building sits in central Osaka and connects easily to local transportation networks. Note that this is a private workspace where access requires authorization from the management.

The building received the BCS Prize for its construction quality and building techniques, a rare recognition for office structures of that period. This award showed that it set standards for modern construction methods in Japan.
