The castle Tokugawa Ieyasu built to assert dominance over Nobunaga's former heartland — early Edo period political architecture in Gifu's southern suburbs.
#144 — Continued 100 CastlesFree admission. The ruins are a public park (Kano Castle Park). Stone walls survive but no structures remain.
Kano Castle is primarily for castle enthusiasts visiting the Gifu area who want to understand the full picture of the region's military history. The stone walls are good quality and well-preserved. Combine with Gifu Castle on the mountain for a complete day of contrasting castle architectural philosophies.
After the Battle of Sekigahara in 1600, Tokugawa Ieyasu ordered Kano Castle built on the southern outskirts of Gifu city specifically to keep watch over the former domain of the Oda clan — a deliberate act of political architecture. The castle was designed to overawe the population of Gifu and assert Tokugawa authority in the heartland of what had been Nobunaga's power base.
While no buildings remain, Kano Castle's stone walls (ishigaki) are among the better-preserved examples in Gifu Prefecture. The nozurazumi stone stacking technique used here — irregular natural stones fitted without cutting — is characteristic of the early Edo period construction. The walls rise to several meters in the park and give a clear impression of the castle's original imposing scale.
Kano Castle was built in the very first years of the Tokugawa period (around 1601), making it an early example of the new political order's architectural ambitions. Unlike Sengoku castles designed purely for war, Kano was built as a political statement — large, formal, and visible.
Visitor Tip
Kano Castle Park is a pleasant local park with cherry blossoms in spring. The stone walls are well-preserved and easy to appreciate. The castle is an easy walk from Gifu Station and makes a good addition to a Gifu Castle (Inabayama) visit on the same day.
hirajiro
Flatland castle — built on flat terrain south of Gifu city, using stone walls and moats rather than natural terrain for defense
kakaku
Core style — main compound with subsidiary compounds arranged around it, using stone walls and water moats
Ruins — stone walls survive but all wooden structures were demolished by 1870 during the Meiji restoration
nozurazumi — Natural stone stacking — irregular stones fitted without cutting, characteristic of early Edo period construction
The surviving stone walls use the nozurazumi technique of early Edo period castle construction. Multiple sections of original ishigaki survive in the park at heights of two to four meters.
Water moats surrounded the castle compounds, using the flat Gifu plain's water availability. Portions of the original moat system remain visible in the park.
Stone Wall System
The stone walls served both defensive and prestige functions in early Edo period castle design — they were expensive to build and demonstrated the lord's wealth and Tokugawa authorization.
Water Moat System
Multiple water moats on the flat Gifu plain created the water barriers that mountain position provided for yamajiro.
Death from the Side
Attackers enter the corridor between walls. The path seems straightforward — but it isn't.
Historical Context — Kano Castle
Kano Castle's layered water moat system required attackers to cross successive moat barriers, each defended by stone walls and gate complexes, before reaching the main compound. On flat terrain with no natural defensive advantages, the moat system was the entire defensive mechanism.
On Tokugawa Ieyasu's order, Okudaira Nobumasa begins construction of Kano Castle south of Gifu city. Its purpose is explicitly political: to assert Tokugawa authority in the former Oda heartland.
Ieyasu's daughter Toku-hime is placed in Kano Castle, adding the personal connection of the Tokugawa family to this political assertion of authority in the Gifu region.
Following the Meiji Restoration, Kano Castle is demolished along with the great majority of Japan's castle buildings. The stone walls are left in place. The site becomes a public park.
Kano Castle is featured regularly in NHK Gifu regional programming covering the early Edo period history of the Gifu area.
Spring (late March to April) for cherry blossoms in the park. Accessible year-round as an outdoor site.
30-45 minutes
Gifu Castle (Inabayama, on the mountain) is far more dramatic and should be the primary Gifu castle visit. Kano Castle adds the Edo period counterpoint to the story.
