Finally, please consider visiting the Saigo Caves which was the last place of Takamori Saigo and the Seinan War. This place is on the way to car road between the city area and the top of the mountain. Therefore, you can choose the timing of your visit either when you go to or return from the top. This is also another popular historical spot but there are just several caves in a line on the cliff. You may feel sad seeing them and imagining Saigo or his soldiers having to choose them as the last place, not a castle-like place.

Later History
In the Seinan War, the remaining castle buildings of the Second Enclosure were also burned down. After that, the castle ruins at the foot of the mountain were used as schools like Kagoshima University. After the university moved to another location, the Reimeikan museum opened in the Main Enclosure in 1983. As for a historical site, the mountain part was first designated as a National Historic Site in 1931. In addition, the foot part is being added to the site based on the achievement of the recent excavation. Kagoshima Prefecture is also considering to restore other structures at Main Enclosure such as turrets and moats in the future.
My Impression
When I saw the Saigo Caves, I felt like Saigo had been in a guerrilla warfare. If he had fought in a final battle of the Sengoku Period, he would have stayed in a castle building such as the Main Tower, like the Toyotomi Clan used to do at Osaka Castle in the summer campaign of the siege of Osaka in 1615, or on the top of a mountain, like Masashige Kusunoki used to do at Chihaya Castle in the siege of Chihaya in 1333. However, the situation and technology had completely changed from those periods. I think Seinan War proved the end of the warriors as well as the end of Japanese castles.
How to get There
If you want to visit the castle ruins by car, it is about a 20 minute drive away from Kagoshima-kita IC on the Kyushu Expressway. There are several parking lots around the castle ruins. You can also use the parking lot of Reimeikan if you enter the museum. If you want to use public transportation, you can take the Kagoshima City-view Bus from Kagoshima-chuo Station and get off at the Satsuma-gishihimae bus stop or take the city tram bound for Kagoshima-ekimae from the station and get off at the Shiyakusho-mae stop. From Fukuoka to Kagoshima-chuo Station: Take the Kyushu Shinkansen super express. From Tokyo to Kagoshima-chuo Station: Take the express bus from Kagoshima Airport after using a plane.
The home base of the Shimazu Clan and the final place of Seinan War
Location and History
Castle is built after Battle of Sekigahara
Kagoshima Castle was the home base of the Shimazu Clan during the Edo Period and is also known as the final battlefield of Seinan War which was the last civil war in Japan in 1877. The Shimazu Clan had been a great warlord in the southern part of the Kyushu Region during the Sengoku Period between the middle 15th and the late 16th Centuries. However, in the fateful Battle of Sekigahara in 1600, the West Squad including the clan was completely defeated by the East Squad, led by Ieyasu Tokugawa who would be the founder of the Tokugawa Shogunate. The Shimazu troops with about 1500 soldiers somehow escaped from the battlefield in the Chubu Region (central Japan) to their home base of Satsuma Province in the Kyushu Region. However, only 80 clan members survived.
The location of the castle
The Shimazu Clan was worried that the shogunate would attack Satsuma Province directly. Therefore, the clan decided to build a new castle as their home base, which was stronger than their previous one like a simple hall. It was built at the foot of the Shiroyama Mountain on the west, which would be used as the final place for emergencies. It had the Main and Second Enclosures which were surrounded by stone walls and water moats from the north, the east and the south. The Main Enclosure had the Main Hall for the lord inside and one of the largest castle gates in Japan, called Goro-mon. However, the defense system of the castle was still not as complex as those of other major castles in Japan, such as the Main Tower, several-level turrets, and high, elaborately bent stone walls. This was because the Satsuma Domain led by the Shimazu Clan also had a unique defense system called Tojo or the Outer Castles. It refers to the domain sending many of its retainers to their local sites and letting them govern and protect it by themselves, which was different from other domains bringing their retainers together in their home base.
Luckily, the shogunate allowed the Satsuma Domain to continue to govern Satsuma Province until the end of the Edo Period. Even in Anglo-Satsuma War in 1863 when the English Navy battleships shot the Kagoshima city area, the castle was not targeted because it didn’t have tall buildings. After the Meiji Restoration, the castle was used as the prefectural office and as a Japanese Army base, but the buildings of the Main Enclosures were unfortunately burned down by an accidental fire in 1874.
Outbreak of Seinan War
The climax event for the castle finally happened in 1877. Takamori Saigo, one of the Three Greatest Heroes of the Restoration, quit all his government posts, being against the other two, Toshimichi Okubo and Takayoshi Kido, and returned to his home of Kagoshima in 1873. He established his private school called Shigakko in the Second Enclosure of Kagoshima Castle in 1874 to educate young warriors. He tried to control the young people gently, however, as a result, he became the head of the rebellion against the government led by Okubo, which eliminated the privileges of warriors, such as having a sword, and it cut their hereditary salaries in 1876. Several rebellions happened in the same year, followed by the largest Seinan War led by Saigo, which occurred in February of 1877.
Saigo with his troops decided to go north and capture Kumamoto Castle. He and his crew were at first optimistic as they were professional warriors and accommodated supporters from other areas in the Kyushu Region, with the total of 30,000 at maximum. While the number of the defenders in the castle was only over 3,000 and many of them were drafted farmers. The Saigo troops even expected that the defenders would soon surrender because some of their leaders had come from Satsuma. However, the defenders, led by General Tani, never surrendered and Okubo sent the reinforcement to the castle. It also had many drafted soldiers, but was more well trained than Saigo expected and more equipped and supplied than the Saigo troops. The government even used advanced information technologies such as telegraph the Saigo troops never had. Saigo had to withdraw from Kumamoto Castle in April and tried to stay in other areas in the Kyushu Region, such as Hitoyoshi Castle, but all failed. He finally declared the dissolution of his troops in August. He and his close warriors of only nearly 400 wanted to have their last and desperate battle in their original home base, Kagoshima Castle.
Last moment of Saigo and Castle
They somehow reached there in the first of September and allocated themselves to the foot area and Shiroyama Mountain. Of course, they were too few to prevent the government troops of as many as 50 thousands from attacking. If it had been in the Sengoku Period, Saigo would have set his stronghold on the mountain, but it was impossible because it could be targeted by cannons. Therefore, he had to stay in the caves in a valley between the mountain and the foot, which would be called the Saigo Caves later on. The government troops completely besieged the Satsuma rebels so that no one could escape. Their full scale attack was done on 24th of September. Saigo was assaulted from his cave, but was shot, and finally killed himself by performing the Harakiri.
