The castle was originally built in 1604 by Mori Terumoto after his defeat at the Battle of Sekigahara.
The castle keep was originally five stories tall before being dismantled during the Meiji Restoration.
The park is home to a specific variety of cherry tree known as the Hagi-zakura.
The stone walls were constructed using a technique that allows them to withstand earthquakes, visible today in the interlocking rock patterns.
The name 'Shizuki' refers to the mountain behind the castle, literally translating to 'the mountain of the moon and the moon's reflection'.
It is one of the few Japanese castle sites that maintains its original water-filled moats surrounding the inner citadel area.
Hagi Castle Ruins Shizuki Park occupies the former site of Hagi Castle, which served as the seat of the Mori clan for 260 years during the Edo period. The site is designated a UNESCO World Heritage site as part of the Sites of Japan’s Meiji Industrial Revolution. Although the main keep was demolished in 1874, the stone walls, moats, and massive defensive ramparts remain intact. The park is situated at the base of Mount Shizuki, providing a natural coastal defense. It is famous for its collection of over 600 cherry trees, which create a significant tunnel effect during the spring bloom. A Shinto shrine, Shizuki-jinja, is located within the park grounds. The park features a traditional tea house where visitors can experience tea ceremonies while overlooking the remains of the castle’s inner enclosure.
