It looks Japanese-ish, right? Well, that's because a lot of Japan's classical-era architecture and aesthetic designs originated from China. When the Tang Dynasty collapsed, many artists, architects, scholars, and generals fled to Japan, where both they and their Chinese knowledge were assimilated into the local culture. During the classical Japanese Heian Era, their society tended to mimic Chinese lifestyle and cultural trends. One example of this is how the great Japanese cities of Kyoto and Nara were actually based off the architectural layouts of Chang'an, China's ancient capital.
