188.Hara Castle Part1

The battlefield of the Shimabara Rebellion

Location and History

Arima Clan builds Castle in Shimabara Peninsula

Hara Castle is known as the place where the Shimabara Rebellion was stopped in 1638. The castle was built near the edge of Shimabara Peninsula, in the western part of the Kyushu Region. The Arima Clan, one of the warlords in the region, first built the castle at the end of 15th Century. Harunobu Arima, the lord of the clan in the late 16th Century, was known as a Christian feudal lord. The Shimabara Peninsula possessed an international trade port called Kuchinotsu Port where Portuguese missionaries started to work in 1563. Christianity spread around the peninsula greatly and the area also prospered from trading. Harunobu originally lived in Hinoe Castle which the clan built many years ago. He renovated Hara Castle at the beginning of the 17th Century, probably as his new home base. However, he was punished by the Tokugawa Shogunate in 1612 before he moved to the castle. His son was also transferred to another place in 1614.

Castle uses Natural Terrain and has Great Stone Walls

Hara Castle was built on several hills alongside Ariake Sea. The Main, Second and Third Enclosures were on different hills. These hills were by the sea with natural steep cliffs. They were divided by large and deep dry moats using the natural terrain as well. The side of the castle facing the land had a swamp. Overall, the castle could be very defensive. In particular, the Main Enclosure was all surrounded by stone walls. Its entrance, called Koguchi, was very large and had a zigzagging route using huge ornate stones. There was the Main Tower or a large turret inside the enclosure. These structures were thought to show the castle’s lord’s authority. The Second and Third Enclosures were made of soil and were probably used as warriors’ houses. The Matsukura Clan following the Arima Clan didn’t use Hara Castle and built a new castle, called Shimabara Castle, as their home base. Hara Castle was once abandoned in 1615, but at least its foundation, including the stone walls, remained.

Shimabara Rebellion happens due to Matsukura Clan’s oppression

The Matsukura Clan oppressed the farmers and Christians in their territory. Being Christian had not been allowed by the Tokugawa Shogunate since 1612. 1n 1637, the people in Shimabara Peninsula, together with the people in Amakusa Islands over Ariake Sea who were in the same situation, rebelled against the Matsukura Clan and the shogunate. They were officially led by a charismatic Christian boy, Shiro Amakusa, but actually guided by the masterless warriors, called Ronin, who were former retainers of the Arima Clan and other Clans.
They first attacked Matsukura’s home base, Shimabara Castle, but failed. Then, they decided to be besieged in Hara Castle by themselves after they repaired it. Historians believe that they were waiting for reinforcements from Christians from other areas of Japan and Catholic countries like Portugal.

Annihilation of rebellion after 3-month siege

The siege started with about 37,000 defenders including women and children in December 1637. The troops from the shogunate first assaulted the castle but failed. Even the commander of the shogunate, Shigemasa Itakura was killed by a shot from the castle, as the counterattacks were professionally instructed and the castle was strong. The shogunate changed its tactics to encircle the castle with over 120,000 soldiers. The siege lasted for nearly 3 months, however, the reinforcements for the uprising army didn’t come. At the end of February 1638, the shogunate attacked the castle in full force when the defenders ran out of food. The castle fell and the rebellion was annihilated.

The survivors of the uprising army’s fate was extremely severe. Almost all of them, except for some runaways, were killed. It is said that many of the Christians hoped to be killed as martyrs. Hara Castle was completely destroyed and buried by the shogunate. The corpses of the executed people were also buried with the castle. The lord of the area, Katsuie Matsukura was executed due to his misgovernment. Shimabara Rebellion was one of the greatest tragedies and had a big impact on Japanese history. This incident accelerated the policy of the national isolation of Japan by the Tokugawa Shogunate.

87.Hizen-Nagoya Castle Part1

Hideyoshi’s largest and last ambition

Location and History

Huge Battle Castle for invasion of Korea

Hizen-Nagoya Castle was a battle castle to support for the invasion of Korea by Hideyoshi Toyotomi, located in the northwestern part of Kyushu Island. Hideyoshi is known as for the ruler who achieved his the unification of Japan in the late 16th Century. He completed it to by defeating the Hojo Clan at Odawara Castle, known as the siege of Odawara in 1590. However, soon after the unification, he declared he would conquer China and ordered the lords throughout Japan to prepare for it in 1591. Many lords and warriors under him also supported his plan to get more territory. They were not able to get new territory in Japan after the unification because there were no more battles.

Hideyoshi also ordered the lords to build a battle castle on Kyushu Island near Korea, known as Hizen-Nagoya Castle. Battle castles were basically used only once and usually simple. Hideyoshi once built another gorgeous battle castle known as Ishigakiyama Castle during the siege of Odawara. However, Hizen-Nagoya Castle was much larger and stronger; it was the second largest just after Hideyoshi’s home base, Osaka Castle. The construction of the castle, divided among the lords, took only 8 months. About 120 lords gathered and also built their own military positions around the castle. The place where the castle was built had originally been a fishing village. However, it became one of the largest cities in Japan in a very short time. Nearly 200,000 soldiers were sent from the castle city to Korea, and over 100,000 people stayed in the city.

Gorgeous and strong castle

Hizen-Nagoya Castle had the Main Enclosure with the five-layer Main Tower and the Main Hall at the highest position. Five routes led to the caste. The main ones were the Main Route, the Back Route and the Yamazato Route. The Main Route went from the south to the Third Enclosure in the east of the Main Enclosure via the Eastern Barbican Enclosure. The Main Gate of the Main Enclosure led to the Third Enclosure. The Back Route started from the outside of the Second Enclosure in the west of the Main Enclosure. However, the route did not go to the Main Enclosure directly, and it went south of it to the Third Enclosure in the east. Some historians speculate the Back route should have been the actual Main Route because it is more defensive. The Yamazato Route led to the Yamazato-maru Enclosure, lower and north of the Third Enclosure. Hideyoshi’s residence with a tea-ceremony house was built in the former. All the enclosures were surrounded by high stone walls, which made the castle strong and showed Hideyoshi’s authority.

Long battle and Breakdown after Hideyoshi’s death

The invasion of Korea started in 1592. That was originally for the conquest of China, but eventually caused a battle with Korea, because of the country was on the way to China. The Japanese Army at first occupied most of Korea instantly. Hideyoshi stayed and instructed the army from Hizen-Nagoya Castle. He was very pleased to hear the good news and even planned how he would divide China and Korea. However, the battle line was stuck in the southern part of Korea due to the reinforcements sent by the Ming Dynasty of China and the countermeasures taken by the Korean volunteer soldiers and navy. In 1593, envoys from the Ming Emperor came to this castle for the cease-fire negotiations.

The negotiations continued for a long time, however, they failed. The war resumed in the southern part of Korea in in 1597. The unmotivated Japanese Army had to fight the useless war with the Ming Military. Many innocent Korean people were also killed. The Japanese Army finally withdrew from Korea immediately after Hideyoshi’s death in 1598. The failure of the war sped up the destruction of the Toyotomi Clan and the foundation of the Tokugawa Shogunate. Hizen-Nagoya Castle was abandoned at the same time and returned to a quiet place.

185.Karatsu Castle Part1

The castle the Terasawa Clan built

Location and History

Area prospered with sea transportation

Karatsu Castle is located in the northwestern part of Kyushu Island, which is now Karatsu City, Saga Prefecture. The area of the city faces Genkai-nada Sea between Japan and Korea. Because of this reason, the area prospered with sea transportation including overseas trade. For example, there was Matsura Province with the port accepting the envoys from overseas nearly 2000 years ago. A warriors’ group, known as the Matsura Group, was very active using navy forces and sometimes pirates in the Middle Ages. In 1588, the ruler, Hideyoshi Toyotomi issued the Act to Ban the Piracy to control sea transportation. After that, Hideyoshi’s retainer, Hirotaka Terasawa was sent to this area to govern it. He was an excellent practical person who supported the military logistics when Hideyoshi sent large troops from Nagoya Castle near his area to Korea.

The location of the castle

Hirotaka Terasawa built Castle

Hirotaka eventually supported the Tokugawa Shogunate and became the founder of the Karatsu Domain. He also built his new home base, Karatsu Castle between 1602 and 1608. The center of the castle was built on Mitsushima-yama Mountain beside the estuary of Matsuura-gawa River. Hirotaka changed the route of the river to place the mountain and other enclosures in a line on the ground like a peninsula. The mountain was the top of the ground towards the sea. That meant enemies were not able to attack the center from the ground easily. The center was also surrounded by stone walls along the sea. Some turrets were built on the stone walls, which were probably used for monitoring the sea. Some sea ports such as Funairi-mon Gate were also built beside the estuary. On the top of the mountain, the stone wall base for the Main Tower was built. However, it is thought that the Main Tower was not built because there has been no evidence of this.

Terasawa Clan fired after Shimabara Rebellion

Hirotaka was also given a new detached territory in the area called Amakusa, in the western part of Kyushu Island by the shogunate due to his contribution. However, this caused the Terasawa Clan’s misfortune. There were a lot of masterless warriors called Ronin who were former retainers of the Konishi Clan who were fired by the shogunate. There were also many Christians which the shogunate banned people from becoming. Hirotaka oppressed both of them in accordance with the shogunate’s instructions. As a result, Shimabara Rebellion, including the people in Amakusa, happened in 1637 in the period of Hirotaka’s son, Katataka. The shogunate took Amakusa away from the Terasawa Clan after the rebellion. Katataka felt anxious and killed himself in 1647 in the end. The Terasawa Clan was fired by the shogunate because of no successor to him.

Karatsu Domain followed by Mizuno and Ogasawara Clans

After that, five clans governed Karatsu Castle and the Karatsu Domain until the end of the Edo Period. Some of the lords became famous in Japanese history. One of them was Tadakuni Mizuno who performed the Tenpo Reforms in the central government as the head of the shogun’s council of elders. Another was Nagamichi Ogasawara who was a member of the shogun’s council of elders, and devoted to the Tokugawa Shogunate till the very last moment before it fell down.
