19.Kawagoe Castle Part1

Kawagoe Castle was located in modern day Kawagoe City of Saitama Prefecture at the central part of the Kanto Region. Its former castle town is known as the street with many Kura storehouses and named as a little Edo, which attracts many tourists. The castle and town were developed with a deep relationship with Edo City (the current Tokyo), the shogun’s capital.

Location and History

Kawagoe Castle was located in modern day Kawagoe City of Saitama Prefecture at the central part of the Kanto Region. The city is known as the street with many Kura storehouses and named as a little Edo, which attracts many tourists. In fact, the streets were mostly rebuilt after Kawagoe Great Fire in 1893 of the Meiji Era, not during the Edo Period. However, the city area originates from the castle town of Kawagoe Castle. In addition, the castle and town were developed with a deep relationship with Edo City (the current Tokyo), the shogun’s capital.

The Kawagoe area is surrounded by curved Iruma River in three directions, the north, east and west. That’s why the city’s name may come from the place you need to go over (Goe) the river (Kawa). The first lord family of the area is said to be the Kawagoe Clan which lived in the western riverside of the Iruma River between the 12th and 14th Centuries. The clan’s residence was still not located in the later Kawagoe Castle. The castle was first built in 1457 by Dokan Ota who was a senior vassal of the Ogigayatsu Uesugi Clan. The clan had been fighting against the Ashikaga Clan since 1455, together with the relative Yamanouchi Uesugi Clan. They confronted at Tone River, the largest river in the Kanto Region. The Uesugi Clans took their positions at the western side of the river, that’s why they needed several new castles behind the river. Kawagoe Castle was one of the three major ones, followed by Edo and Iwatsuki Castles.

Stage of Night Battle of Kawagoe

Kawagoe Castle eventually became the home of the Ogikayatsu Uesugi Clan. When the clan had an internal conflict with the Yamanouchi Uesugi Clan during the beginning of the 16th Century, the castle became the frontline of the battle. This was because the Yamanouchi Uesugi Clan reused the former Kawagoe Clan’s residence as its encampment across the Iruma River. During their internal fighting, the Hojo Clan invaded the Kanto Region and finally captured Kawagoe Castle in 1537. Both Uesugi Clans noticed their crisis and made peace with each other to get the castle back. The clans’ large troops surrounded the castle which was owned by Tsunanari Hojo in October of 1545.

The castle was still small at that time and located at the edge of Musashino Plateau with few enclosures made of soil. However, it was protected by natural waterlogged areas around the Iruma River in three directions, the north, south and east. It was thought that artificial ditches and moats were built in the other direction and around the castle. In April of 1546, Ujiyasu Hojo, the lord of the clan reinforced the castle. He announced that he and the castle would surrender to the Uesugi Clans, which threw them off their guard. On 20th of April, Ujiyasu started a night attack against the Uesugi Clans, which was called the Night Battle of Kawagoe. A severe battle happened at Tomyoji Temple, just about 800m away from the center of the castle. That resulted in the Hojo’s hegemony and the Uesugi’s destruction in the region.

Place to Stay for Shoguns

The region was owned by the Tokugawa Clan at the end of the 16th Century and the Tokugawa Shogunate was established in 1603. Edo Castle became the shogun’s home, so Kawagoe Castle became an important defense for Edo Castle to the north. That’s why the Sakai Clan, which was trusted by the shoguns, became the lords of Kawagoe Castle. Oher than that, the 1st shogun (Ieyasu) and the 3rd shogun (Iemitsu) often stayed in Kawagoe Castle when they went hunting. There was an episode which indicated their relationship with Kawagoe as following. The Kitain Temple in Kawagoe was re-established by Priest Tenkai who was also trusted by the shoguns in 1599. However, it was burned down by a great fire in 1638. The shogun, Iemitsu ordered to immediately restore the temple, offering some Edo Castle’s buildings including his birth room and his foster mother, Lady Kasuga’s make-up room. They are remaining in the temple.

Important Defense and Satellite City for Edo

The castle and the area around were followed by several other hereditary vassals of the shoguns as the Kawagoe Domain. Some of them became members of the shogun’s council of elders in the central government. One of them, Nobutsuna Matsudaira improved the castle. He doubled the castle’s range by building new enclosures, turrets and gates. However, the castle was still basically made of soil without the Main Tower, which looked like a group of halls. To prevent enemies from invading, complex routes were built with earthen walls, mud walls, and water moats, instead of high stone walls and turrets in other castles. The castle town was also developed with Kawagoe Road, Shingashi River as waterways, and agricultural land. As a result, the town prospered by providing their products, such as Somen noodles, silk goods, and Kawagoe sweet potatoes which is still popular, to Edo City which was already one of the largest cities in the world.

The center of the castle was the Main Hall in the second enclosure. While the main enclosure had been used as the loggings for the shoguns it was abandoned for sometime. After the Main Hall was burned down in 1846, the Kawagoe Domain decided to rebuild the hall in the main enclosure. Although the domain was facing huge financial problems due to being in charge of the coast guard of Edo Bay against possible invasions form the Western ships, the hall was completed in 1848 thanks to lots of additional taxes and donations from locals.

18.Hachigata Castle Part1

Hachigata Castle was located in modern day Yorii Town in the northern part of Saitama Prefecture. The castle was prominent both when the Sengoku Period of the Kanto Region started and ended.

Location and History

Hachigata Castle was located in modern day Yorii Town in the northern part of Saitama Prefecture. The castle was prominent both when the Sengoku Period of the Kanto Region started and ended.

Beginning of Sengoku Period in Kanto Region

The location of the castle

The region ran into the unquiet Sengoku Period in 1455 when the Kyotoku War began. The Ashikaga Clan, the shogunate head for the Kanto Region and the Uesugi Clan, the shogunate deputy for the region opposed and confronted each other at the Tone River, the largest river in the region. The Uesugi Clan constructed Ikkako Encampment at the western riverside and used it for over 20 years. The clan actually consisted of two branch clans, the Yamanouchi and the Ogigayatsu Clans. Each branch clan also had a main retainer to control many warriors and matters from the Nagao Clan for the Yamanouchi and the Ota Clan for the Ogigayatsu. One of the main retainers, Kagenobu Nagao died in 1473 before his position was assigned by his boss, Akisada Yamanouchi to his little brother, Tadakage.

Kageharu Nagao builds Castle

This was a reasonable decision, because Tadakage was considered as a senior and experienced person. However, Kagenobu’s son, Kageharu thought otherwise, as the position was inherited by his grandfather and father. Kageharu left the encampment, built Hachigata Castle in 1475, and started a rebellion in 1476. The castle was built on a high cliff at the meeting point of Arakawa River, another large river in the region, and Fukasawagawa River, a peninsula affording natural defense. Though the details of the first stage of the castle are unknown, it would have been easy for Kageharu to attack the Ikkako Encampment which had no guard on its southern side (which faced the castle). Many other retainers, who worried about their own positions in the new power hierarchy, supported Kageharu. The encampment finally collapsed in 1477.

What Kageharu really wanted was unclear, but he tried to get many territories with his supporters and the Ashikaga Clan with whom Kageharu took sides. Kageharu was an excellent general. However, the other main retainer for the Ogigayatsu, Dokan Ota was superior to him. Dokan, who is known for building Edo Castle, which would become the center of the government during the Edo Period , and is now the Imperial Palace, was also a great strategist and politician. Dokan captured the Kageharu supporters’ castles, such as Kozukue Castle, one by one. He also made brokered a fragile peace with the Ashikaga Clan, which drove Kageharu back to his home base, Hachigata Castle. Dokan finally attacked and captured the castle in 1478, so Kageharu was forced to flee. Dokan became the greatest lord in the Kanto Region, however, he was killed in 1485 by his master, Sadamasa Ogigayatsu who feared his power. The region became unstable again and Kageharu continued to fight against his masters, the Yamanouchi, throughout his life as a soldier of fortune. He finally settled down under Sozui Ise, the founder of the Hojo Clan, until his death in 1514.

Castle becomes Hojo’s Branch

Hachigata Castle was occupied by the Yamanouchi for a while, but eventually abandoned. The power of the Uesugi Clans (Yamanouchi and Ogigayatsu) decreased while the Hojo Clan invaded the Kanto Region during the 16th Century. The Hojo Clan was based in Odawara Castle in Sagami Province (now Kanagawa Pref.) and they set several important branch castles where the Hojo’s relatives were sent to govern the region’s stability. Hachigata Castle was chosen as one of the castles as its location was at the northern edge of their territory. Ujikuni Hojo became the lord of the castle in 1568 and struggled to keep. For example, when the Hojo Clan allied with Kenshin Uesugi who was the successor of the Yamanouchi and one of the strongest warlords, Ujikuni was charged with negotiating with him. However, once the alliance was broken, Kenshin attacked Hachigata Castle, set fire to its castle town, and withdrew.

Ujikuni Hojo, Last Lord of Castle

To survive under these severe conditions, Ujikuni greatly improved the castle. The castle’s defenses were naturally strong, having been built on a tall cliff, sandwiched by the two rivers to the north, the east, and the west. It also had many enclosures made of soil, mainly including the Main, Second and Third Enclosures in a line from north to south. Therefore, enemies would have to attack the Third Enclosure first from the south. To prevent attack, these enclosures were divided by deep dry moats and surrounded by high, thick earthen walls. Part of the walls were supported by stone mounds looking like stone walls. The entrances of the enclosures were protected by a set of gates and the Umadashi system. The Umadashi system refers to a connected smaller enclosure in front of the gate, connected by a narrow path to the larger enclosures. The position could be used to both protect the enclosure and attack from it.

The history of the castle suddenly ended in 1590 when the ruler, Hideyoshi Toyotomi invaded the Kanto Region as the Hojo’s territory to complete his unification of Japan. He went there with over 200,000 soldiers and about 35,000 of which, attacked Hachigata Castle in May, led by Toshiie Maeda. Ujikuni, along with about 3,000 defenders, was besieged for a month. The attackers didn’t assaulted the castle, directly, instead, it is said that they fired large guns from Kuruma-yama Mountain, about 1 km away from the Main Gate of the castle to the south. Ujiie finally surrendered and opened the castle in June, perhaps because there was no hope for reinforcements, or due to the damage from the guns. The castle passed to the Tokugawa Clan, who now ran the region instead of the Hojo Clan, however, it was eventually abandoned at the end of the Sengoku Period.

16.Minowa Castle Part1

The castle of Narimasa Nagano, the strongest general

Location and History

Nagano Clan builds Castle in Sengoku Period

Minowa Castle was located on a hill at the foot of Mt, Haruna in Kozuke Province which is now Gunma Prefecture. The Nagano Clan first built this castle at the start of the 16th Century during the Sengoku Period. The clan was thought to originally be an official family of the local government in the ancient times, and eventually became a powerful local lord in the Middle Ages. They had lived near the Provincial Office on a plain land in the center of the province. However, it got dangerous to continue to do so, because many battles happened all over the Kanto Region since the late 15th Century. That’s why the clan built the castle beside the mountain area near western part of the province.

The location of the castle

Narimasa Nagano fights alone

The Nagano Clan worked under the Uesugi Clan, the governor of Kozuke Province. Norimasa Uesugi, the lord of the clan at that time, was defeated by the Hojo Clan from the south in the Battle of Kawagoe Castle in 1546. After that, he escaped from Kozuke Province to Echigo Provence in the north of the Kozuke Province. As a result, most of the local lords supported the Hojo Clan. However, Narimasa Nagano who was the lord of the clan, didn’t do so, showing his loyalty to the Uesugi Clan. He was considered as one of the strongest generals at that time, against large warlords such as the Hojo and Takeda Clans. He organized a group of local lords in the region, called the Minowa Group, to maintain their territories. He even accommodated some other generals who lost their territories due to defeats of battles, such as Yukitaka Sanada.

After some years of his binding time, Kenshin Uesugi, the successor of Norimasa, invaded the Kanto Region including Kozuke Province from Echigo Province in 1560. Narimasa became one of senior vassals of the Uesugi Clan again and succeeded to be the lord of the western Kozuke Province. However, when Kenshin returned to his home base, Kasugayama Castle in Echigo Province, the Hojo Clan started to get the territories back. In addition, Narimasa tried to subject the Obata Clan in Kunimine Castle to the southwest of Narimasa’s territory, but failed. This was because Nobuzane Obata, the lord of the clan, asked Shingen Takeda, one of the greatest warlords, for help and became his retainer. Yukitaka Sanada, who was saved by Narimasa, also became a senior vassal of Shingen after leaving Narimasa. Shingen was a lifetime competitor of Kenshin, so he started to invade the western Kozuke in 1561.

Castle falls with Destruction of Nagano Clan

Narimasa could somehow maintain Minowa Castle and the area around in his life, but died of illness in 1561. His son, Narimori Nagano followed his father’s way not to surrendering to their enemies. However, Shingen did a full-scale attack on Minowa Castle in 1566 before the castle fell. Narimori and his relatives fought to the end and finally killed themselves in the Gozen Enclosure of the castle. It is said that they threw the memorial tablets of their ancestors into the well in the enclosure before their deaths.

After that, Nobuzane Obata changed their master to the Oda and Hojo Clans to maintain their territory after the destruction of the Takeda Clan. In 1590, when the ruler, Hideyoshi Toyotomi invaded Hojo’s Kanto Region, Obata’s own castle fell, then the clan loss their territory as well. On the other hand, the Sanada Clan struggled to be independently based in Ueda, Numata and Iwabitsu Castles. They finally succeeded to achieve this, however it was very hard to climb.

Naomasa Ii modernizes and abandons Castle

After Minowa Castle fell, the Takeda Clan owned the castle, followed by the Oda, Hojo and Tokugawa Clans. Naomasa Ii, the head of senior vassals of the Tokugawa Clan, was the last lord of the caste. He entered the castle when the Tokugawa Clan was moved to the Kanto Region in 1590. Minowa Castle was large, but originally had enclosures mainly made of soil, surrounded by dry moats. Naomasa improved and modernized the castle as much as he could. For example, he developed new enclosures such as the Inari Enclosure with a water moat to be more defensive. Stone walls were built alongside the Main Route to show the castle lord’s authority. Some turret gates were also built in the important positions of the castle, such as the Kaku-umadashi Western Entrance Gate. However, Naomasa finally moved to his new home base called Takasaki Castle on a plain land in 1598 before Minowa Castle was abandoned.
