135.Masuyama Castle Part1

An important mountain castle in Ecchu Province

Location and History

Ecchu Province in Sengoku Period

Masuyama Castle was a large mountain castle which was located in Ecchu Province (what is now modern day Toyama Prefecture). In the first 16th Century, Ecchu Province didn’t have a strong warlord, but was divided between the Jinbo Clan, the Shina Clan, the Ikkoshu Sect and others. The province had the Toyama Plain in the center, which was surrounded by hills in the south, the east and the west. They built a lot of mountain castles on the area of the hills to maintain their territories. Masuyama Castle was called one of the three greatest mountain castles in Ecchu Province followed by Moriyama Castle and Matsukura Castle.

The location of the castle

Masuyama Castle was located on the western edge of the hills sticking out of the Toyama Plain from the south. The Wada-gawa River flowed alongside the edge, so it could be a natural water moat. There were a lot of enclosures on the hill such as the First Enclosure and the Second Enclosure.

Defensive system of Masuyama Castle

To protect these enclosures, the castle had several defensive systems using natural terrains like ridges, cliffs and valleys. For example, some ridges were cut artificially to look like a trench, called Horikiri. Some cliffs were cut vertically, called Kirigishi. Some valleys were used as the dry moats called Karabori.

The soldiers could also get water from several wells easily in order to survive a long siege. Other castles such as Kameyama Castle were built on the hill next to Masuyama Castle so that they could work closely with each other. Even the castle town was developed on the foot of the mountain castle at its peak.

Kenshin Uesugi attacked it three times

It is uncertain when the castle was first built, but the Jinbo Clan owned the castle in the middle of the 16th Century during the Sengoku Period. In 1560, a great warlord by the name of Kenshin Uesugi invaded Ecchu Province and supporting the Shina Clan from Echigo Province (The east of Ecchu Province). The Jinbo Clan was sieged in Masuyama Castle to protect themselves. Kenshin wrote in his letter that Masuyama was an essentially dangerous place and impenetrable with lots of defenders. Kenshin attacked Masuyama Castle three times, and finally captured it in 1576.

After Kenshin died in 1578, Narimasa Sassa under the Oda Clan took over Masuyama Castle from the Uesugi Clan in 1581. After that, the Maeda Clan supporting the ruler, Hideyoshi Toyotomi and the Tokugawa Shogunate later owned the castle. Some senior vassals from the Maeda Clan stayed in the castle. That meant Masuyama Castle was always an important castle to rule that area. However, the castle was finally abandoned in 1615 due to the Law of One Castle per Province created by the Tokugawa Shogunate. It was said that a wife of the senior vassal who was called Sho-hime was also a daughter of Toshiie Maeda, the founder of the Maeda Clan who managed the castle around the end of its history.

33.Takaoka Castle Part1

Is it just a retirement place for Toshinaga Maeda?

Location and History

Takaoka Castle was located in what is now Takaoka City, in the western part of Toyama Prefecture. This castle’s life is generally said as following fasts. Toshinaga Maeda, the founder of the Kaga Domain built the castle for his retirement in 1609. However, the castle was abandoned in 1615 due to the Law of One Castle per Province by the Tokugawa Shogunate, soon after Toshinaga’s death in 1614. The castle was officially 6 years old. Is it really correct?

Toshinaga was a son of Toshiie Maeda, a great warlord in the late 16th Century. While Toshiie lived in Kanazawa Castle in Kaga Province (now part of Ishikawa Pref.), Toshinaga was given his own territory in the western part of Ecchu Province (now Toyama Pref.) by the ruler, Hideyoshi Toyotomi in 1585. Toshinaga stayed in this territory for 12 years. He first lived in a mountain castle called Moriyama Castle, but soon started to develop farming, transportation and residential area on the plain land called Sekino at that time, Takaoka later. It is thought that he also had a site like a castle on the plain area although no records remain. In 1597, he got another territory in the middle part of Ecchu Provence, then he moved to Toyama Castle to develop the new territory.

After his father, Toshiie died in 1599, Toshinaga lived in Kanazawa Castle and became the founder of the Kaga Domain by supporting the Tokugawa Shogunate. The domain had the largest territory including almost of all the three provinces (Kaga, Ecchu and Noto) in the nation except for the shogunate. He needed many castles and sites to govern the large territory, and the site, which would be Takaoka Castle later, was probably also included to them. In 1605, he handed over the head of the domain to his younger brother, Toshitsune, and moved to Toyama Castle again for retirement. However, he actually had the power to govern the domain because his successor was still young.

When Toyama Castle was unfortunately burned down in 1609, Toshinaga had to find his new castle to stay, which would be called Takaoka Castle. Takaoka Castle and its castle town were rapidly constructed in just half a year, while Toshinaga renamed the land from Sekino to Takaoka. However, a local historian says the foundation and the water moats for the caste must have been there before the construction. The water moats were so well designed that they have never been dried by the supply of groundwater for more than 400 years. It would be impossible to build such an advanced system in a short time at that time. The historian speculates that Toshinaga had prepared the foundation and the water moats for Takaoka Castle for possible events like battles.

Even after Takaoka Castle was officially abandoned in 1615, Toshinaga’s followers kept the foundation and the water moats, and they built warehouses on it. They probably felt the same way as Toshinaga. That’s why we can now see almost the same foundation and the water moats as Toshinaga’s period. Takaoka Castle has much longer history than what is officially said.

121.Motosakura Castle Part1

The castle of the Chiba Clan, an illustrious clan in Kanto Region

Location and History

Chiba Clan built it in 15th Century

Motosakura Castle was a large castle which was located in Shimosa Province (what is now the northern part of Chiba Prefecture). A warlord, Suketane from the Chiba Clan, first built the castle at latest in 1484 on a hilly area called Masakado-yama. The area was surrounded by Inba-numa Lake, and only open to the Shimosa Road on flat land in the southern direction. This meant the area was defensive and convenient for water and land transport.

Central portion, Inner Compounds.

When the castle was first built, the warlords in the Kanto Region were split into two groups, the western group and the eastern group. The western group was led by the shogunal deputy for the Kanto Region, the Uesugi Clan, and the eastern group was led by the head of the Kanto government in Koga, the Ashikaga Clan. The Chiba Clan was included in the eastern group and the Motosakura Castle was also an important site which connected Koga in Shimosa Province to the other provinces in Boso Peninsula inside the group. The clan built several enclosures in the central portion of the castle called the Inner Compounds.

The location of the castle

The Main Enclosure called Shiro-yama had the Main Hall for the lord of the castle. The hall had a set of two formal buildings called Shuden and Kaisho, because the clan was the governor of the province. The Okuno-yama enclosure, which had the Myoken Shrine where the clan went for worship, is next to the main enclosure on the west. The Okuno-yama enclosure was connected to the Main Enclosure by a wooden bridge . The next one is the Kura-ato Enclosure which had warehouses. The westmost one is the Settei-yama Enclosure which was used for guesthouses. In addition to these enclosures, the Higashi-yama Enclosure was set to protect them, and the Tokoji-byo Enclosure, which had temples, faced Inba-numa Lake.

Outer Compounds were built against Satomi Clan

In the middle of the 16th Century, the situation of the Kanto Region changed. The Hojo Clan captured most of the region, then the Chiba Clan decided to support Hojo by adopting a son from them. However, the Satomi Clan in Boso Peninsula (the south of Honsakura Castle) was against Hojo. As a result, the Chiba Clan had to reinforce the defense of the castle on the south.

The location of Motosakura Castle and the home base of the Satomi Clan

The clan built large enclosures outside the Inner Compounds, called the Outer Compounds such as Araue, Negoya, and Mukai-Negoya. They were surrounded by thick earthen walls and had the sticking out defensive positions called Umadashi, which were built using Hojo’s techniques. In addition, the Settai-yama Enclosure became the pivot of the defense because it was the connecting point between the Inner Compounds and the Outer Compounds. The range of the castle finally reached 39,000 square meters.

However, The Chiba Clan was fired by the ruler Hieyoshi Toyotomi in 1590, as their master Hojo Clan was also defeated by Hideyoshi. After that, Motosakura Castle was sometimes used by several clans. The castle was finally abandoned in 1615.
