Kitayama Castle (Uozu City, Toyama Prefecture) Complete Guide | History, Highlights, and Access Information
What is Kitayama Castle?
Kitayama Castle (Kitayama-jo) is a mountain castle from the Sengoku period located in Uozu City, Toyama Prefecture. Also known as Kanayama Castle and Kanayama Valley Castle, it holds a significant place in history as an important military base in Etchu (present-day Toyama Prefecture).
Uozu City is located in the northeastern part of Toyama Prefecture and is characterized by its long, narrow shape facing Toyama Bay. Due to the short distance from the Northern Alps to Toyama Bay and the unique topography where elevation rises rapidly from sea level to mountainous areas of 2000 meters, Kitayama Castle occupied a strategically important position.
Although only some remains today, it is a valuable historical site for castle enthusiasts and history buffs, allowing them to imagine what Etchu was like during the Sengoku period.

Background and Era of Construction
While there are various theories regarding the exact date of construction of Kitayama Castle, it is generally believed to have been built around the 16th century during the Sengoku period (Warring States period). During this time, Etchu Province was a battleground for the power struggles of multiple Sengoku daimyo, including the Uesugi, Takeda, and Oda clans, and the Toyama Bay coastal region, including Uozu, was a crucial strategic location.
The area around Uozu City was a vital point for transporting goods using the Toyama Bay sea transport system, and also held an important position as a gateway to the inland areas. Kitayama Castle is thought to have been built to take advantage of these geographical conditions, for the purpose of territorial control and defense.
Lords and Changes
It is presumed that Kitayama Castle was ruled by powerful local lords, but detailed records are limited. The history of Etchu Province during the Sengoku period was a turbulent era, from Uesugi Kenshin’s pacification of Etchu, to the subsequent invasion by Oda Nobunaga’s forces, and finally to Toyotomi Hideyoshi’s unification of Japan.
It is believed that Kitayama Castle, too, was affected by the changing of rulers and eventually abandoned during this period of history. It was undoubtedly influenced by battles fought in the surrounding area, such as the Battle of Uozu Castle.
Abandonment and the Present
With the end of the Sengoku period, like many mountain castles, Kitayama Castle ceased its military role and was abandoned. While it gradually faded from people’s memories after the Edo period, recent advances in castle research have led to a re-evaluation of its historical value.
Currently, its remains are being confirmed and preservation efforts are underway by local history enthusiasts and castle researchers.
Structure and Layout of Kitayama Castle
Location and Utilization of Topography
As a mountain castle, Kitayama Castle skillfully utilized the natural terrain. Located in the mountainous area of Uozu City, it was built on high ground overlooking the surrounding area. This location allowed for early detection of approaching enemies and provided a favorable defensive position against attacks.
Located in a position to monitor the road leading from Toyama Bay inland, it is believed to have functioned as a military base controlling a crucial transportation hub.
Characteristics of the Remains
While the remains that can be confirmed today are limited, the following characteristics are observed:
Kuruwa (enclosure): A flat area at the center of the castle where buildings were constructed. Multiple kuruwa have been confirmed at Kitayama Castle, suggesting a layout centered around the main enclosure.
Horikiri (moat): A moat dug to cut across a ridge, an important defensive structure to prevent enemy intrusion. A structure unique to mountain castles, it has also been confirmed at Kitayama Castle.
Dorui (earthen rampart): A defensive wall made by piling up earth, positioned to surround the kuruwa.
These remains have weathered over time, but careful observation allows us to imagine what the castle looked like at the time.
Defensive System
As a mountain castle, Kitayama Castle had a defensive system that made maximum use of the natural terrain. The steep slopes acted as natural fortifications, and by focusing on defending the limited access routes, the castle could be effectively protected even with a small force.
The arrangement of multiple baileys in a stepped pattern demonstrates a multi-layered defense strategy, ensuring that even if the outer fortifications were breached, the next line of defense would stop the enemy.
