Renovation of Sumi Memorial Hall

Sumi Memorial Hall, designed by Kenzo Tange, was constructed in Ichinomiya City, Aichi Prefecture in 1957 as the head office of Tsuyakin Kogyo Co., Ltd.  The building shows features of Tange’s early works; open and bold structure, double beam girders, wooden ceilings and partitions, and exposed concrete finishing.  Its architectural value being recognized, it has been specified as a registered tangible cultural property since 2008.  The ownership of the building was transferred to the Ichinomiya City Government in 2010, and the city decided to renovate it by retrofitting it for use as a lifelong learning center and community center.  It is rare in Japan for a building registered as a cultural property to be utiliized for public facilities. The seismic retrofit was carried out by reinforcement of the pillars and installation of steel braces, with care not to impair the original design, and was completed at the end of September. It is expected that the renovated building will be utilized for various activities for citizens and vitalize the region as a communication center.
