Architect Kengo Kuma reflects on the Tokyo Sony building’s legacy.
M+ curators recently had to spring into action to acquire fragments of Tokyo’s iconic Sony Building, completed in 1966 by Japanese architect Ashihara Yoshinobu (1918—2003), before its demolition as part of the Ginza Sony Park Project in the run-up to the Tokyo Olympics. Thanks to a quick response and a generous donation from Sony, M+ acquired several building components. Located in Ginza, the Sony Building has been a symbol of Japan’s post-World War II recovery. To reflect on the building’s legacy, we invited architect Kengo Kuma, a student of Ashihara, to share his memories of the building.
Kengo Kuma: Japanese post-war architecture is arguably epitomised by architect Tange Kenzo (1913—2005). Tange designed the Yoyogi National Stadium for the Tokyo Summer Olympics in 1964, which became a symbol of Japan’s post-war industrialisation and high economic growth. It was overwhelmingly striking to a ten-year-old boy’s mind, and inspired me to study architecture.
However, in reality, I was a far more frequent visitor to the Sony Building in Ginza, which was completed in 1966 by architect Ashihara Yoshinobu, two years after the Yoyogi National Stadium. It was simply more fun, and I believe I subconsciously learned a lot from it.
The relationship between the floor and the ground, for example. The building’s spiralling floor levels rose as an extension from the ground. While modernist architects in America, such as Marcel Breuer, also used closely-spaced split-level floors to create a spiral circulation, Ashihara added a humanistic ambience, reminiscent of Japanese streets, to realise the Sony building.
The use of elegant aluminium louvres cladding the façade also characterises Ashihara’s remarkable style, contrasting with Tange’s powerful concrete forms. Again, Ashihara combined Le Corbusier’s solid concrete brise-soleil with the lightness of a Japanese wooden lattice. His airy louvres had a profile that determined, through meticulous calculation, how to let light through in the most efficient way. I learned this from Ashihara himself when I attended university.
Looking back on it today, Ashihara was the architect who bridged the gap between the ‘tough Japan of an industrialised society’ exemplified by Tange Kenzo, and the ‘soft and genial Japan of a post-industrialised society’ that we are currently living in. It is not an exaggeration to say that it was thanks to Ashihara that contemporary Japanese architecture was able to enter this new state.

Kengo Kuma is an architect and a professor at the Graduate School of Architecture, University of Tokyo. His architectural projects include the Suntory Museum of Art and Nezu Museum, both in Tokyo, the Great (Bamboo) Wall house outside Beijing, and, as part of a joint venture, the forthcoming National Stadium for the 2020 Tokyo Olympics.
The Sony building had a staircase, popular amongst children, that played musical notes on a ‘Do Re Mi’ scale as one ascended and descended its steps.
