Since the Osaka head office, built in 1961, was starting to show signs of ageing, the company decided to carry out a full renovation to mark its 75th anniversary in 1993. Renovations were completed in January of that year. For the renovation, the cutting-edge SSG (Structural Sealant Glazing) method using glass curtain walls was selected, with the frameless glass creating a beautiful flat appearance. The building also made use of many of the company’s advanced products, such as the high-efficiency heat-reflecting glass REFSHINE™ and MULTILITE™ double glazing. In addition, the ground floor featured a music hall with an optimum acoustic space, which was opened to the general public as a place of recreation and relaxation.
