Iiyama Castle

Iiyama Castle is a Japanese fortification on a hilltop with three main enclosures arranged from south to north, each featuring stone walls and multiple gates. The layout follows the natural terrain, with defensive structures positioned to control the surrounding landscape.

The site was rebuilt in 1564 by Kenshin Uesugi during the Warring States period to serve as a forward base against the advancing Takeda clan. This renovation reflected the military priorities of that era, making it a key strategic position in regional conflicts.

The inner enclosure now houses a shrine, while the middle section serves as public green space with preserved stone walls. Walking through these areas, visitors see how the historical site has become part of everyday community life rather than remaining separated from it.

The grounds are reachable on foot in about five minutes from Kita-Iiyama Station, with free parking available near Castle Park. Wear sturdy shoes as the hilltop pathways are steep and uneven in places.

Several original castle gates survive scattered around the area, including a two-story gate relocated from a private residence to the southern middle gate site. This unexpected preservation of individual structures shows how parts of the fortification were absorbed into the surrounding community.
