Tomisaki Castle, located in Tomisaki, Fuchu-machi, Toyama City, Toyama Prefecture, was a mountain castle also known as “Takiyama Castle” during the Sengoku period. Built by the Jinbo clan, it was an important fortress in Etchu Province and is an indispensable part of Toyama City’s history. This article provides a detailed explanation of Tomisaki Castle’s history, from its construction to its abandonment, its current remains, and access methods.
What is Tomisaki Castle? | Basic Information and Overview
Tomisaki Castle was a mountain castle located in Tomisaki, Fuchu-machi, Toyama City, and is currently designated as “Toyama Castle Card No. 21.” Built on the hilly area on the west bank of the Jinzu River, this castle was an important base supporting the Jinbo clan’s power base in western Etchu Province.
Alternative Names and Designations of the Castle
Tomisaki Castle has been known by different names throughout history. During the Sengoku period, it was called “Takiyama Castle,” and some historical records use this name. It was affectionately known as “Tomisaki Castle” among local residents, and currently, “Tomisaki Castle” is the official name.
Location and Geographical Characteristics
Tomisaki, Fuchu-machi, Toyama City, is located on the west side of the Jinzu River, in a hilly area overlooking the Toyama Plain. This terrain maximized the defensive capabilities of a mountain castle, providing ideal conditions for monitoring the surrounding area and serving as a military base. Located west of central Toyama City, it is one of the historical centers of the current Fuchu region.
History of Tomisaki Castle | From Construction to Abandonment
Construction by Jinbo Hachirozaemon (1441)
The history of Tomisaki Castle begins in 1441 (Kakitsu 1), when it was built by Jinbo Hachirozaemon. This period was the mid-Muromachi period, a time when the Jinbo clan, the shugodai (deputy governor) of Etchu Province, was expanding its power. The Jinbo clan needed to build a castle in a strategically important location to solidify their control over western Etchu Province.
Jinbo Hachirozaemon, a member of the Jinbo clan, established a base for governing the surrounding region by constructing a castle in this area. At that time, Etchu Province was plagued by intense conflicts over the position of shugo (provincial governor) and power struggles among local clans, making a strong castle essential for controlling the territory.
Tomisaki Castle in the Sengoku Period | Its Role as Takiyama Castle
During the Sengoku period (Warring States period), Tomisaki Castle came to be known as “Takiyama Castle.” During this period, Etchu Province became a fierce battleground, with multiple forces, including the Uesugi clan, the Ikkō-ikki (Buddhist uprisings), and the Oda clan, vying for power. While the Jinbo clan maintained Tomiyama Castle as their main castle, they continued to maintain Tomisaki Castle as an important subsidiary castle.
The name Takiyama Castle is thought to derive from the surrounding topography and water system. It strengthened its function as a mountain castle and served as a fort protecting the Jinbo clan’s sphere of influence. It is presumed that Tomisaki Castle played a part in the castle network of Etchu Province during the Sengoku period, working in conjunction with Toyama Castle to defend the region.
The Jinbo Clan and the Turmoil in Etchu Province
The Jinbo clan boasted great power as the deputy governor of western Etchu Province, but their power rose and fell repeatedly amidst the turmoil of the Sengoku period. In particular, during the time of Jinbo Nagashige, they were forced to endure fierce battles, including conflicts with Uesugi Kenshin and resistances against the Ikkō-ikki.
It is thought that Tomisaki Castle was also affected by these turmoil. As the Jinbo clan’s power declined, the importance of the castle likely changed as well. Ultimately, with the downfall of the Jinbo clan, Tomisaki Castle disappeared from the historical stage.
The Time and Circumstances of the Castle’s Abandonment
There are no clear records regarding the exact date of Tomisaki Castle’s abandonment. However, considering the historical context of the decline of the Jinbo clan and the unification of Etchu Province by the Maeda clan, which led to the abandonment of many small and medium-sized castles, it is presumed that Tomisaki Castle was abandoned sometime between the late 16th and early 17th centuries.
With the advent of the Edo period, the Kaga Domain (later the Toyama Domain was established as a separate domain) implemented the “One Castle Per Province” decree, resulting in the demolition of many castles other than Toyama Castle. It is believed that Tomisaki Castle completely lost its function as a military facility during this period.
Layout and Structure of Tomisaki Castle
Defensive Function as a Mountain Castle
Tomisaki Castle possessed the typical characteristics of a medieval mountain castle. It made maximum use of the hilly terrain, utilizing natural fortifications as defensive lines. The steep slopes characteristic of mountain castles acted as natural barriers, making enemy intrusion difficult.
Estimated Castle Structure
Although detailed layout maps do not exist, comparing it to castles associated with the Jinbo clan of the same period, the following structure is presumed:
- Main Enclosure (Honmaru): The central enclosure of the castle, believed to have housed the lord’s residence and command post.
- Second and Third Enclosures: Secondary defensive lines protecting the main enclosure.
- Moats and Earthworks: Moats dividing the ridge and earthworks reinforcing defenses.
- Gate Entrance: An important defensive point serving as an entrance to the castle.
Water Source and Logistics
Securing a water source is crucial for mountain castles. Based on the topography around Tomisaki Castle, it is presumed that wells or springs were used. Furthermore, a food storage facility for provisions was likely located within the castle.

Relationship between Tomisaki Castle and the Jinbo Clan
History of the Jinbo Clan and their Rule of Etchu Province
The Jinbo clan was a family that wielded significant influence from the Muromachi period to the Sengoku period as the deputy governor of Etchu Province. Originally vassals of the Hatakeyama clan, the governor of Etchu Province, they gradually built their own independent power.
The Jinbo clan’s base was Toyama Castle, but they established several branch castles to govern their territory. Tomisaki Castle served as one of its important subsidiary castles, acting as a base for the defense and governance of the western region.
Relationship with Toyama Castle
Toyama Castle is believed to have been built in 1543 (Tenbun 12) by Jinbo Nagashige, but the Jinbo clan had already held power in western Etchu Province before that. Tomisaki Castle existed before the construction of Toyama Castle and may have been one of the Jinbo clan’s early bases.
Even after Toyama Castle was developed as the main castle, Tomisaki Castle continued to function as a subsidiary castle, and it is thought that the two castles worked together to protect the Jinbo clan’s territory.
Key Figures of the Jinbo Clan
- Jinbo Hachirozaemon: Builder of Tomisaki Castle (1441)
- Jinbo Nagashige: Sengoku daimyo who built Toyama Castle (16th century)
- Jinbo Nagazumi: Warrior who fought against Uesugi Kenshin and the Ikko-ikki
