181.Kokura Castle Part1

The top floor of the Main Tower hanged out, which was called Western Style. This was because its balcony and handrails were covered by black outer walls to prevent damage from bad weather and strong wind.

Location and History

Castle is built as Bridgehead in Kyushu

Kokura Castle is located in the Kokura area of Kitakyushu City at the northern edge of the Kyushu Region. For example, if you visit the region using a Shinkansen super express, the first station will be Kokura Station near the castle. The area was more well known as the entrance of the region, which had Kokura Port facing the Kanmon Strait, sandwiched by Kyushu Island and the main island of Japan. That’s why warlords, who wanted to invade the region from the mainland, tried to build a bridgehead in this area. Certain records say that Motonari Mori, who was a great warlord of the Chugoku Region, built it in 1569, which would be the former Kokura Castle. After the ruler, Hideyoshi Toyotomi invaded the region in 1587, he gave the castle to his trusted vassal, Katsunobu Mori. However, Katsunobui was eventually fired because he was against Ieyasu Tokugawa, who would become the next ruler, in the decisive battle in 1600.

Tadaoki Hosokawa renovates Castle

Instead, Tadaoki Hosokawa (also known as Sansai after his retirement), who had greatly supported Ieyasu in the battle, was assigned as the lord of Buzen Provence including the Kokura area and would be the founder of the Kokura Domain. He first lived in Nakatsu Castle, which the former lord of the castle, the Kuroda Clan had built, but soon started to renovate the castle in Kokura in 1602 as his new home, which would be what we call Kokura Castle.

The former castle and the port was along the large estuary of Murasaki River, like a bay, when Tadaoki greatly developed the area. The area was broadly separated into the Western and Eastern Enclosures, binding the river. The Western Enclosure was also divided by water moats into smaller sub enclosures, such as the Main Enclosure, for the lord and warriors. The Eastern Enclosure became the castle town for people like merchants, craftsmen and monks. Furthermore, the whole area was surrounded by other natural or artificial rivers as the outermost moat whose perimeter was about 8km. Tadaoki thought if a large enemy force attacked the castle, he would flood the enemy by breaking the banks of the rivers.

Characteristic Main Tower

The main portion of the castle was surrounded by high stone walls. In particular, the stone wall base for the Main Tower was built at the northeastern corner of the Main Enclosure and was 18.8m high. The Main Tower itself was 22.8m high, so 41.6m in total. The tower had 4 levels and 5 floors inside because they were no roofs between the fourth and fifth floors. Also, the existing roofs were very simple without any decorations except for the top. It is a method called Soto-siki (meaning multi-storied type). This method made the builders efficient and made the tower easier to protect. The defenders would actually look out over the surronding area and counterattack the enemies at any direction from the tower. In addition, the tower had one more feature called Nanban-zukuri (meaning Western Style) or Kara-zukuri (the Chinese Style). It refers to some of the levels or floors hanging out over the other levels of the tower. In the case of Kokura Castle, it was the top floor because its balcony and handrails were covered by black outer walls to prevent damage from bad weather and strong wind. This Kokura style would be later emulated by other castles like Tsuyama and Takamatsu Castles.

Prosperity and Destruction of Ogasawara Clan

The castle and the domain were followed by Tadazame Ogasawara Ogasawara in 1632 after the Hosokawa Clan was transferred to Kumamoto Castle of the Kumamoto Domain. The Ogasawara Clan was a hereditary feudal lord family of the Tokugawa Shogunate, so it was expected to monitor non-hereditary feudal domains in the Kyushu Region. While the government of the Kokura Domain became stable, its castle town commercially prospered, especially around Tokiwa Bridge which connected the Western and Eastern Enclosures over the Murasaki River. The bridge was also the starting point of the Nagasaki Road where many passengers came and went between the main land and the region. the lords in the region and the Korean Envoys also used the road when they went to Edo.

Meanwhile, a bad sign for the castle occurred in 1837. The Main Tower was unfortunately burned down by an accidental fire though it had survived through some lightning strikes. The tower was not rebuilt by the domain after that. Next, a severe event happened to the castle at the end of the Edo Period. The Choshu Domain at the edge of the mainland over the Kanmon Strait rebelled against the shogunate twice. The Second Conquest of Choshu was planned by the shogunate in 1866. The shogunate ordered the Kokura Domain and its allies to attack the Choshu through the Kokura Route, one of the four battlefields.

The battles on the Kokura Route started in June. Against all odds, the Choshu troops landed on the Kokura area and counterattacked the shogunate side instead. Moreover, all the allies withdrew after they heard about the death of the shogun, Iemochi Tokugawa, by illness on the 20th of July. The Kokura troops, which were left alone, finally fired at the castle by themselves on the 1st of Aug and continued to fight against the Choshu like a guerrilla army. However, the fall of the castle and the Choshu capturing it became a symbol of the shogunate’s big failure in the battles which would accelerate its destruction and the Meiji Restoration by the New Government including the Choshu Domain.

74.Iwakuni Castle Part1

The castle is reflected by Hiroie Kikkawa’s life.

Location and History

Hiroie saves Mori Clan

Iwakuni is known for its beautiful scenery from Kintaikyo bridge which has five magnificent wooden arches. The bridge over Nishikigawa River also has a good background of a mountain with the Main Tower of Iwakuni Castle. Visitors may think they all remain as they were, however, the castle has many episodes, in fact, and had a tough life.

Hiroie Kikkawa was the founder of the castle, who also was a senior vassal and relative of the Mori Clan. The clan governed most of the Chugoku Region with an earning of 1.2 million koku of rice at the end of the 16th Century. However, after the ruler of Japan, Hideyoshi Toyotomi died in 1598, the situation became unstable. Many lords tried to rely on Ieyasu Tokugawa, the largest one in eastern Japan with 2.5 million koku as the next ruler, while others including Mitsunari Ishida still supported the Toyotomi Clan. Mitsunari tried to make the lord of the Mori Clan, Terumoto Mori as their leader because the clan was the largest lord in western Japan. The opinions inside the clan were divided. One is to support Mitsunari and become the next ruler instead of Ieyasu, mainly insisted by Ekei Ankokuji, the other is to support Ieyasu to maintain their territory, objected by Hiroie.

When the Battle of Sekigahara happened in 1600, Terumoto became the head of the West Quad which was actually led by Mitsunari, because being a ruler was attractive to him. Hiroie was a cool-headed commander who knew his master couldn’t take over the East Quad led by Ieyasu. Therefore, he contacted Ieyasu secretly and promised that his troops would not do anything in the battle in exchange for maintaining the Mori’s territory. As a result, Ieyasu defeated Mitsunari. However, after the battle, Ieyasu found out the evidence that Terumoto had wanted to be a ruler. Ieyasu decided to take all the Mori’s territory away from Terumoto and give two provinces (Nagato and Suo) of it to Hiroie. Hiroie urged Ieyasu to give the provinces to Terumoto instead of him. In the end, Mori’s territory was formally reduced from a worth of 1.2 million koku to only 370 thousand koku of the two provinces, known as the Choshu Domain.

Iwakuni Castle is built in Hiroie’s new territory

Hiroie had to stand in a difficult position. He was actually the hero of the Mori Clan, but many members of it thought he was a destroyer. He was finally given by the clan a small territory with 30 thousand koku, which was the eastern edge of the Choshu Domain. Hiroie started to build a new castle as his home base in 1601, which would be called Iwakuni Castle. He first built his residence called Odoi beside Nishikigawa River which could be the natural Outer Moat. The residence was also surrounded by the artificial Inner Moat. After that he developed the mountain part of the castle mainly by building the Northern, Main and Second Enclosures on the ridge from the north to the south. They were all surrounded by stone walls and the Main Enclosure had the four-level Main Tower. The castle was completed in 1608.

Hiroie’s hard decision to destroy Mountain part

However, another difficulty was coming to Hiroie after the Tokugawa Shogunate defeated the Toyotomi Clan in 1615. The Tokugawa Shogunate ordered all the lords in Japan to destroy all the castles except for one castle where the lord lived by issuing the Law of One Castle per Province in the same year. The shogunate tried to prevent any other lords from rebelling based on many strong castles. According to this law, Iwakuni Castle could survive because the castle could be the only one castle in Suo Province and the shogunate still considered Hiroie’s Kikkawa Clan as an independent lord. However, the Mori Clan didn’t allow it as they thought that the Kikkawa Clan was just a retainer of them, not an independent lord. The controversial relation between Hiroie and the Mori Clan since the Sekigahara Battle remained. Hiroie had to choose to destroy the castle considering the future relationship with the Mori Clan.

Intentionally broken stone walls on the mountain

The mountain part was actually destroyed but the residence beside the river survived for living. It was formally called Iwakuni Encampment, not Castle until the end of the Edo Period. Kintaikyo Bridge was first built in 1673 by the third lord of the clan, Hiroyoshi Kikkawa to connect his residence with the castle town which had been built at the opposite side of the river. This bridge could be seen as a symbol of the peace at that time.

170.Hamada Castle Part1

The castle which was destined to fight the Choshu Domain

Location and History

Castle is built to monitor Choshu Domain

Hamada Castle was located in Iwami Province which is modern day the western part of Shimane Prefecture. You may think the prefecture has a comparatively quiet image, but the province was very important during the Sengoku and Edo Periods. This was because it had Iwami Silver Mine, which has become a World Heritage Site. The mine was owned by several great warlords as the Ouchi, Amago, and Mori Clans, then finally followed by the Tokugawa Shogunate. The shogunate wanted to secure the mine, but there was still the Mori Clan in the Choshu Domain, next to Iwami Province in the west. They handed it over the shogunate after the losing the Battle of Sekigawara in 1600, however, the shogunate feared they would retaliate again. That was probably why the shogunate created new domains as Tsuwano in 1600 and Hamada in 1619, located between the mine and Choshu. The shogunate expected the two domains to monitor the Choshu Domain regularly.

The location of the castle

Shigeharu Furuta, who had been the lord of Matsusaka Castle in Ise Province, was ordered to move to Iwami Provence as the founder of the Hamada Domain in 1619. He was looking for a suitable site for the new castle and eventually found a 67m high hill beside Hamada Port which would be the best location. In fact, building a new castle was prohibited by the Tokugawa Shogunate at that time, but it was allowed for the new domain as an exception. The castle construction started in 1620, its foundation was made in the same year, and its completion was in 1623. Although general techniques for castle construction had been advanced back then, those for Hamada Castle were relatively low. For example, the stone walls of the castle were piled together using roughly processed stones while others often used precisely cut stones. The Main Tower for the castle was a Lookout Tower, but it was considered an older one. The reason for it is uncertain, but it may be because the construction was needed to be finished quickly, or that the craftsmen for the construction were locals.

Castle is handed over from Furuta Clan to Matsudaira Clans

The Furuta Clan was unfortunately fired by the shogunate due to its internal conflict as well as having no successor in 1648. After that, the Matsui-Matsudaira Clan (which had been the Matsui Clan under the Imagawa Clan, and was allowed to use the Matsudaira family name by Ieyasu Tokugawa due to their contributions to him) governed the domain and castle for a long time. However, the clan was moved to another in 1836 as a punishment for the smuggling of Joseon dynasty of Korea. Instead, the Ochi-Matsudaira Clan (which originated from the 6th Shogun, Ienobu Tokugawa’s little brother) came to govern them. At the end of the Edo Period, Takeakira Matsudaira was adopted as the last lord, who was also a little brother of Yoshinobu Tokugawa who would be the last shogun.

Hamada warriors burn Castle by themselves when attacked by Choshu

The biggest event for the castle occurred in 1866 when the shogunate ordered lords in Japan to join in the Second conquest of Choshu. The shogunate tried to defeat the Choshu Domain which was its enemy. The Hamada Domain was ordered to attack the Choshu Domain through the Iwami Route which connected both domains. However, the Tsuwano Domain, which should have supported the shogunate, took a neutral position because the power of the shogunate began to decrease. On the other hand, the Hamada Domain had to join it because its lord was a relative of the shogun. Contrary to their expectations, the Hamada troops with some other domains’ were unfortunately beaten by the Choshu’s well-trained drafted soldiers. The Choshu troops counterattacked and got close to Hamada Castle and town, and forced them to surrender.

The lord, Takeakira once made up his mind to stay in the castle to be killed in a battle. However, he was eventually persuaded to escape from the castle towards his outland territory in Mimasaka Province (now part of Okayama Pref.). The Choshu troops managed to capture Hamada Castle as well as Iwami Silver Mine which the shogunate and Hamada Domain must have secured. There was an interesting episode where the warriors of the domain withdrew from the castle. They burned the castle by themselves during the escape. This was because handing it over to their enemies intact was rather shameful than being used as a base by the enemy. The reason for it is as followed. The Main Tower on the top managed to survive the fire and remained for a while. However, some people in Hamada still won’t admit to the fact and say the tower must have been burned by the Hamada Domain itself. That means the castle was the entity which must never be separated from its masters at that time. That was the warrior’s all or nothing mentality.
