Nagato Province

Nagato Province (長門国, Nagato no kuni^?), often called Chōshū (長州^?), was a province of Japan. It was at the extreme western end of Honshū, in the area that is today Yamaguchi Prefecture. Nagato bordered on Iwami and Suō Provinces.

Although the ancient capital of the province was Shimonoseki, Hagi was the seat of the Chōshū han (fief or domain) during the Edo period. Nagato was ruled by the Mōri clan before and after the Battle of Sekigahara.

In 1871 with the abolition of feudal domains and the establishment of prefectures (Haihan Chiken) after the Meiji Restoration, the provinces of Nagato and Suō were combined to eventually establish Yamaguchi Prefecture. At the same time, the province continued to exist for some purposes. For example, Nagato is explicitly recognized in treaties in 1894 (a) between Japan and the United States and (b) between Japan and the United Kingdom.
