Nihonmatsu Castle

Nihonmatsu Castle, also known as Kasumigajo, is a hilltop fortress on Mount Hakukigamine in the city of Nihonmatsu. The site features restored stone walls, reconstructed gates, and watchtowers that reflect the typical design of Japanese feudal fortifications.

Hatakeyama Takakuni founded the fortress in 1341 during the Nanboku-chō period, using the natural elevation for defense. The Niwa family took over during the Edo period and held it until the Boshin War in 1868, when the castle fell during the Battle of Nihonmatsu.

The grounds hold the Senshintei teahouse, a cultural property moved here from inside the original fortress during the Meiji era. Visitors today can see traditional teahouse architecture and experience the atmosphere of a historic retreat once reserved for castle lords.

The walk from JR Nihonmatsu Station to the entrance takes about 20 minutes, with another 15 minutes uphill to the main bailey at the summit. The paths climb through wooded sections, so comfortable shoes are recommended for the visit.

The grounds serve as the exhibition space for the Nihonmatsu Chrysanthemum Doll Festival between October and November, featuring life-sized figures shaped from thousands of chrysanthemums. The tradition of this display dates back to 1955 and attracts many visitors each year.
