49.Odani Castle Part1

A large mountain castle the Azai Clan built

Location and History

Azai Clan built Castle as their Home Base

Odani Castle was a large mountain castle located in the northern part of Omi Province, which is now Shiga Prefecture. A local warlord of the Azai Clan, built the castle around 1520’s during the Sengoku Period. However, the clan was unfortunately defeated at this castle in 1573. As a result, the castle has been known to many people for Azai’s tragedy.

The range of Omi Province and the location of the castle

Omi Provence had been a very important location connecting western and eastern Japan. The Shoguns and rulers wanted to own or take control over this province. That’s why Nobunaga Oda made an alliance with Nagamasa Azai who was the lord of the clan by getting his sister Oichi married with Nagamasa before he went to Kyoto in 1568. However, Nagamasa rebelled against Nobunaga in 1570 when Nobunaga attacked the Asakura Clan which was another ally of the Azai Clan. The long battle between Nobunaga and Nagamasa had started.

Castle is improved to fight against Nobunaga Oda

Odani Castle was built on a ridge of Odaniyama-Mountain (at 495m). It had many enclosures with halls which were surrounded by stone walls. It is thought that they were for living and showing authority to people rather than for battles at its first stage. This was because the lord of the castle sometimes escaped from the castle when it was attacked. However, in order to fight against Nobunaga, the castle was improved as a strong fortress with the help of the Asakura Clan. The castle also had many branch castles such as Ozuku Castle on the top of the mountain to protect the back side of Odani Castle.

Nagamasa and the Asakura Clan fought against Nobunaga on a field in the Battle of Anegawa in 1570 but were beaten. Then, he decided to stay in Odani Castle waiting for his allies, the anti-Nobunaga Network beating Nobunaga. Nobunaga gave up making an aggressive attack on the castle, instead, he took actions to make it isolated bit by bit. His retainer such as Hideyoshi Hashiba persuaded some of Nagamasa’s retainers to support Nobunaga. That resulted in some branch castles of Odani Castle belonging to Nobunaga’s side without battles.

Castle is isolated after long battle, then falls

Nobunaga also built a new battle castle called Toragoze-yama Castle as his stronghold in front of Odani Castle. This made Nobunaga get supplies easier, while making it much more difficult for Nagamasa. In 1573, Nobunaga drove the Asakura Clan away from the most important branch, Ozuku Castle which they had held and captured it. Moreover, Nobunaga chased the clan down to their home base, Ichijodani Castle, and defeated them. As a result, Odani Castle was completely isolated.

In the castle on the ridge, Nagamasa was at the Main Enclosure in the lower part and his father, Hisamasa was at the Komaru Enclosure in the upper part. Nobunaga’s retainer, Hideyoshi Hashiba rushed up from the foot to the Kyogoku-maru Enclosure in the middle part and captured it on Aug 27th. That meant the castle and the Azai Family were divided. Hisamasa fell into crisis and killed himself performing Hara-kiri on the same day. Nagamasa held on for a few more days, but finally killed himself in the same way as his father, and the castle fell on Sep 1st.

Fates of Namasa Azai’s wife and children

Oichi, who was Nobunaga’s sister, but also Nagamasa’s wife, had still been at the castle and was saved by Nobunaga. She and Nagamasa had three daughters and at least one son. These daughters were also saved and later known as Azai’s Three Sisters including the oldest Chacha being Hideyoshi’s wife after he became the ruler of Japan. The son called Manpuku-maru was unfortunately killed as a common rule at that time not to be revenged by him. The heads of Nagamasa and Hisamasa’s were on public display in Kyoto also as another common rule. Nobunada made skull cups using their heads to share them with his retainers in a party. There were many different common practices at that times from us.

157.Hachimanyama Castle Part1

The castle of Hidetsugu Toyotomi, the tragic Kanpaku

Location and History

Twisted Life by his uncle, Ruler Hideyoshi

Hachimanyama Castle was located beside Lake Biwa in Omi Province which is now Shiga Prefecture. The castle was built by Hidetsugu Toyotomi, the tragic Kanpaku ( the chief adviser to the Emperor). He was a nephew of Hideyoshi Toyotomi who was the ruler of Japan in the late 15th Century. His mother was Hideyoshi’s older sister called Tomo. He was twisted around Hideyoshi’s little finger throughout his life, but left this castle and its castle town which is now Omi-Hachiman City.

The location of the castle

Hidetsugu was born in 1568 during the Sengoku Period when his uncle, Hideyoshi worked under a great warlord, Nobunaga Oda. In 1572 when he was 4 years old, he was adopted by Hideyoshi to the Miyabe Clan in Omi Province, which Hideyoshi wanted to gain over to Nobunaga’s side. It was common for warriors at that time to ally with others, but in the case of Hideyoshi, he had to send his nephew because he had no children. After that, Hidetsugu was adopted again to the Miyoshi Clan in Shikoku Island where Nobunaga and Hideyoshi aimed to invade. However, the situation changed after Nobunaga died in the Honnoji Incident in 1582. Hideyoshi intended to be the ruler, so he wanted Hidetsugu to be one of his commanding officer. Hidetsugu fought hard for his uncle in many battles although he failed in one of them called the Battle of Nagakute in 1584. In 1585 when Hideyoshi was appointed Kanpaku as the ruler, Hidetsuku was given a large territory in Omi Province. Hidetsugu built a new castle as his home base with instructions from Hideyoshi, called Hachimanyama Castle.

He develops new Castle, Castle Town, and Waterways

The mountain, which the castle was built, had originally been often called Hachimanyama or Hachiman Mountain, because the Himure-Hachimangu Shrine had been on the top of the mountain. The first thing to do for building the castle was to move the shrine to the foot. The mountain was 294m high and 180m above from the foot. Its slopes were very steep, which was good for protecting the castle. The Main Enclosure was built on the top where it is said the Main Tower and Main Hall were built. The Second, the Northern and the Western Enclosures were also built on the ridges spread from the top. These enclosures were all surrounded by stone walls. The Barbican Enclosure was also built below the Western Enclosure. In addition, the luxury residence for Hidetsugu was built at the foot because the top was not convenient for living. The long and straight Main Route like Azuchi Castle was also built in front of it.

Hidetsugu also developed the castle town beside the mountain by moving the merchants in the castle town of the abandoned Azuchi Castle to the new developed area. The city area was built in a grid pattern like modern cities to improve business and living. Hidetsugu built the Hachiman-bori Moat, connected to Lake Biwa, between the castle and town. The moat was basically for defense, but it was also used for water transportation to boost commerce. The town has been prospering even after the castle was abandoned.

Short Glory before his Harakiri Incident

Hidetsugu moved to a much larger territory and finally became Kanpaku as the successor of Hideyoshi in 1590 . This was because Hideyoshi’s real or adopted male children all died young. Hidetsugu communicated well with many nobles and lords to be the next ruler after Hideyoshi. However, the situation changed again when Hideyoshi had his last son, Hideyori in 1583. In 1585, Hidetsugu was suddenly summoned by Hideyoshi’s officers due to the suspicion of his rebellion against Hideyoshi. He was sent to Mt. Koyasan, without any meeting with Hideyoshi, and He was forced to commit Harakiri. (ritual suicide by disembowelment with a sword.). Hideyoshi also ordered to execute almost all of Hidetsugu’s wives and children as offenders. Many relative nobles and lords were also punished. Hidetsugu’s mother, Tomo who was Hideyoshi’s sister felt deep sorrow, then established the Zuiryuji Temple alone in Kyoto to pray for Hidetsugu and his family.

However, no evidence for Hidetsugu’s rebellion was found. Some people said the incident happened for that he was called the Killer Kanpaku, which meant he liked killing, but it was also quite uncertain. After all, it seemed that Hidetaugu was a victim of Hideyoshi who finally became a crazy dictator and initiated a conflict between officers and lords. Hideyoshi even ordered to destroy Hachimanyama Castle followed by the Kyogoku Clan after Hidetsugu. The clan had to move to another castle, called Otsu Castle. There is an interesting story about Hikone Castle, whose Main Tower was moved from Otsu Castle. Toyotomi-style roof tiles covered with golden leaf were found at Hikone Castle which the Tokugawa Shogunate built. Some people think it was impossible as because they were against each other. Some historians speculate that the Main Tower or other buildings Hidetsugu built might have been moved or used to build Otsu Castle by Kyogoku Clan and finally brought to Hikone Castle.

140.Genbao Castle Part1

The stronghold of Katsuie Shibata in the Battle of Shizugatake

Location and History

A castle built against Hideyoshi Hashiba

Genbao Castle was located on the border between Echizen and Omi Provinces, which are modern day Fukui and Shiga Prefectures. It was built by Katsuie Shibata who owned Echizen Province when the Battle of Shizugatake happened in 1583. After the ruler, Nobunaga Oda died in the Honnoji Incident in 1582, his senior vassals, Katsuie and Hideyohsi Hashiba argued against each other over the initiative. Hideyoshi invaded the northern Omi Province, which Katsuie had owned, and started to build many battle castles near the border of Echizen Province which was the home base of Katsuie. Katsuie also confronted Hideyoshi by building his own battle castles around the border. Genbao Castle was the center of these battle castles and Katsuie’s stronghold. Part of its name Genba comes from an official post.”Genba” is the name given to warriors who are highly respected, but it is uncertain whose official name it came from.

Enclosures on Mountain Top

The castle was built on the top of Nakauchio Mountain which was 445m high and also the border. It was also able to control the road over a mountain pass between the provinces, called Tone-toge near the castle. The enclosures of the castle were built on the top of the ridge from the north to the south. The front of the castle was open to the south, the mountain pass and Omi Province where Hideyoshi invaded. Because of that, the southern side of the castle was strongly protected with two enclosures in line. On the other hand, the northern side had the largest enclosure which was used as a military post. The Main Enclosure was the center of the castle, where Katsuie probably lived. It had a Main Tower or large turret, and attached three projecting small enclosures called Umadashi or Overhang for defense.

Sakuma Morimasa’s offensive vs Hideyoshi’s counterattack

On the 16th of April 1583, Katsuie’s ally, Nobutaka Oda fought an army at Gifu Castle in Mino Province against Hideyoshi. Hideyoshi went to Mino Province to crush it on April 17th. Katsuie thought it was a good opportunity to attack Hideyoshi’s side. Morimasa Sakuma, who worked under Katsuie, moved onward to capture some of Hideyoshi’s battle castles on April 19th. However, that was Hideyoshi’s trap. Morimasa succeeded in capturing a battle castle, and wanted to get one more called Shizugatake Fortress. Then, Hideyoshi immediately got back to his original position and counterattacked Morimasa on April 20th. Katsuie and Morimasa were finally defeated by Hideyoshi. An old biography about Hideyoshi called Hoan Taikoki, published in 1626 by Hoan Oze, says Morimasa’s reckless actions caused his destruction although Katsuie advised him to withdraw after his first attack. Many Japanese people have believed it for a very long time.

Is Most Important Factor Toshiie Maeda’s withdrawal?

Recent studies show Morimasa’s actions were not critical. Toshiie Maeda, another ally of Katsuie, who would be a great lord after Hideyoshi became the ruler, eventually withdrew without Katsuie’s permission at the same time as Hideyoshi’s counterattack. It was the decisive trigger for Hideyoshi’s victory and Katsuie’s lost. Why didn’t Hoan describe this most important factor? The answer is that Hoan was a dependent of the Maeda Clan. The action of Toshiie Maeda, the founder of the clan, was probably promised to Hideyoshi, but later people would think it was a betrayal. It was thought Hoan was not able to record this fact which may be a shame of Maeda, therefore he blamed another person for the lost. Genbao Castle was strong, but was meant to work closely with other battle castles. Katsuie had to withdraw from the castle without a battle when his ally gave up on the duty.
