Works
Watanabe is known in particular for designing the Imperial Household Museum, the Hattori Clock shop and the Daiichi Seimei Insurance Building in Tokyo. In 1931, a competition was held to replace the original Imperial Household Museum building. This had been designed by Josiah Conder, and completed in 1882. However, it was destroyed by an earthquake in 1923. Watanabe won the competition with a design that followed the lineage of Imperial Crown Style, having a neo-classical base topped with tiled and gabled Japanese-style roofs. Although constructed from reinforced concrete, some elements of the building alluded to traditional Japanese timber construction techniques. It is today known as the Honkan building at the Tokyo National Museum. The Dai-ichi Seimei building is located across the street from the main entrance to the Imperial Palace grounds in the Marunouchi area of Tokyo. It was chosen by General Douglas MacArthur as the site for Allied Headquarters from 1945-1952.
