Imperial Crown style

The Imperial Crown style (帝冠様式, Teikanyōshiki)、(帝冠式 , Teikanshiki) is a style of Japanese architecture that developed in the 1920s and reached its peak in the 1930s until the end of World War II.

The style ran contrary to modernism and put emphasis to include traditional architectural elements. Buildings in this style were characterised by having a Japanese-style roof such as the Tōkyō Imperial Museum (1937) by Hitoshi Watanabe and Nagoya City Hall and the Aichi Prefectural Government Office.
