History

In the medieval period, Hagi was dominated by the Yoshimi clan, who built Hagi Castle, the ruins of which can be visited today. The Mōri clan became daimyōs of Chōshū Domain at the beginning of the Edo period and built Hagi Castle at the foot of Mt. Shizuki in 1608. They transferred the capital of the domain from Hiroshima to Hagi at the same time. Hagi then developed as the political center of Chōshū for over 250 years.
When the Meiji Restoration came about in the 1860s, as the result of efforts by samurai from Chōshū and a number of other domains, this small city gained great historical significance. Many Japanese statesmen and Prime Ministers were born and brought up in this city.
On March 6, 2005, Hagi absorbed the towns of Susa and Tamagawa, and the villages of Asahi, Fukue, Kawakami and Mutsumi (all from Abu District) to create the new, expanded city of Hagi.
Population
One of the factors underlying the continual decrease of population is said to be its poor public transport. Industry did not grow at all and the rapid economic growth of Japan only caused the town to decline. But it also kept the traditions alive and the traditional look of the town preserved.
