Kyoto (京都) and originally Heian-kyo (平安京), is a major city in Japan known for having served as its imperial capital for centuries since the Heian period. It was originally modelled after the Tang capital of Chang'an in China. It served as the seat of power for the Ashikaga shogunate from 1333 until 1573. During the Sengoku period, Chaya Shirōjirō Kiyonobu kept on eye on Christian missionaries and report any Templar activities to Tokugawa Ieyasu, a daimyo aligned with the Assassins.
With the establishment of the Tokugawa shogunate, its prominence was superseded by that of the shogunate's capital, Edo. After the Imperial Court won the Boshin War, they relocated to Edo, rechristening it as Tokyo, and making it the new national capital.
