Nagaoka-kyō (長岡京) was the capital of Japan from 784 to 794. Its location was in Otokuni District, Yamashiro Province, corresponding to a 4.3 x 5.3 kilometer area spanning the borders of the modern cities of Mukō and Nagaokakyō, Kyoto, the town of Ōyamazaki, and the Nishikyō-ku ward of the city of Kyoto. The ruins of the palace have been found in the Kaidecho neighbourhood of the city of Mukō and have been designated as a National Historic Site since 1964, with the area under protection expanded in 2016.
