国会議事堂
In the early twentieth century, a distinctive style of architecture was developed for the empire. Now referred to as Imperial Crown Style (帝冠様式, "teikan yōshiki"), before the end of World War II, it was originally referred to as "Emperor's Crown Amalgamate Style", and sometimes "Emperor's Crown Style" (帝冠式, Teikanshiki). The style is identified by Japanese-style roofing on top of Neoclassical styled buildings; and can have a centrally elevated structure with a pyramidal dome. The prototype for this style was developed by architect Shimoda Kikutaro in his proposal for the Imperial Diet Building (present National Diet Building) in 1920 – although his proposal was ultimately rejected. Outside of the Japanese mainland, in places like Taiwan and Korea, Imperial Crown Style architecture often included regional architectural elements.
