A hill on the sea and a river delta
After the Battle of Sekigahara, the Mori clan was cut down to two provinces, Suo and Nagato, and had to find a site for a new castle. Three candidates were considered: Yamaguchi, Hofu and Hagi. After talks with the shogunate, Mt. Shizuki in Hagi, which juts into the Sea of Japan, was chosen. Hagi sits on a delta between two rivers, convenient for moving goods by river and sea.[2]

Built by Mori Terumoto
The castle was built by Mori Terumoto, grandson of the warlord Mori Motonari. Terumoto had served as nominal commander of the Western Army at Sekigahara, and after the defeat his lands shrank from eight provinces to two. Work began in 1604, he moved into the partly built castle that same year, and it was completed in 1608.[2]

A castle on both hill and plain
Hagi Castle is a hill-and-plain castle (hirayamajiro): a fortress called the Tsumemaru on the summit of Mt. Shizuki, plus the main, second and third enclosures at its foot. Sea cliffs on the north and west sides of the hill guarded the castle's back. The main enclosure held a five-tier keep and the lord's palace, and three rings of water moats surrounded the castle.[1][2]

Historical record
The government moves, and the castle comes down
For about 260 years Hagi Castle was the political center of the Hagi domain. In 1863 the 13th lord, Mori Takachika, moved the domain government inland to Yamaguchi because Hagi, on the coast, was hard to defend against foreign warships. In 1874, early in the Meiji era, the keep, turrets and gates were all dismantled.[2][1]

Walls, moats and a World Heritage castle town
The stone walls and inner moat survive well, and the site became a National Historic Site in 1951. Shizukiyama Shrine was built on the main enclosure in 1879, and the grounds are now Shizuki Park. The castle site inside the middle moat is part of the "Hagi Castle Town" component of the World Heritage Site "Sites of Japan's Meiji Industrial Revolution". The five-tier keep has been recreated in virtual reality.[2][3]
