188.Hara Castle Part2

You can see the extensive castle ruins.

Features

Large hills and valleys in Castle Ruins

Today, the ruins of Hara Castle are still large with a perimeter of about 4km. The Main Enclosure has mainly been public owned and developed for visitors. The many other areas of the ruins, including the Second and Third Enclosures, are private owned and used as fields. If you walk around and look over the ruins, you can find the large hills and valleys and picture the castle remains. Generally, enclosures of many castles in Japan usually worked closely with each other. However, looking at the enclosures of Hara Castle, they seemed to work independently like a modern fortress. This may be the reason why that the uprising army fought had as equals with the shogunate.

Walking around Second and Third Enclosures

If you drive to the ruins, you will park at the parking lot between the Second and Third Enclosures beside the sea. You will have to walk for about 800m from the parking lot to the Main Enclosure. During the walk, you can see how large the castle was. If you turn right at the first intersection after passing the ruins of the Main Gate, you will reach the monument of Shigemasa Itakura at the Third Enclosure. He was shot and killed here in the first phase of the Shimabara Rebellion.

Going back to the route leading to the Main Enclosure, you will see the spacious Second Enclosure on the left and its Barbican on the right. Locals say the bones of as many as 20,000 uprising people are still buried under the fields.

One of the Greatest Main Enclosure Entrances

As you approach the Main Enclosure, you will see its great stone walls still surrounding it. However, they were to be excavated after being almost buried by the shogunate. Even historians did not expect the castle had to have such great stone walls. Of course, the stone walls were much higher before the destruction.

The stone walls of the Main Enclosure, which were discovered by the excavation

Its entrance, called Koguchi, was also excavated and has been developed for visitors. In fact, this is where the bones of the killed uprising people, which were buried with the stone walls, were found. It had large connected square spaces, called Masugata, forming a maze protecting the entrance. Historians speculate that visitors in the past had to turn 5 to 10 times in the entrance to enter the enclosure. The excavation discovered that the Koguchi entrance of Hara Castle was one of the largest examples of those ever found in Japan.

Inside of Main Enclosure has become Square

The inside of the Main Enclosure is basically a square now. There are the ruins of the Main Enclosure Gate, the Turret base, and the Ikejiri-guchi Gate along the perimeter. There are also the monument of the Shimabara Rebellion, the statue of Shiro Amakusa, and so on. This enclosure stands on the steep cliff by the sea, so you can enjoy a great view of Ariake Sea, and Mt. Unzen in the distance.

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.

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.
