丸子城跡

It is fairly well-maintained, with an observatory for the tower. Up to the observation deck is half of the process. 15 to 30 minutes to the castle ruins The view is very good and the explanations are solid.

I read and went to Taihei Sanada. The feeling of Yamashiro is overflowing and you can feel the history of Sanada. The grass was overgrown, and there were hard sideways that seemed to get lost when going there, but the roads going to Honmaru and Sannomaru were pretty easy to walk on. Personally disliked). There is a observatory in the shape of a kite, and the view from there is so amazing that you can't hear it! I could see the surrounding mountains all over and surrounded the river in three directions, so I think it was strong. There was also a signboard with explanations, and I was able to go by convincing one by one what it was. The age of the castle is unknown, and the castle owner is said to be Maruko. After that, it became Sanada's castle. Maruko Castle is at the forefront of history during the battle of the first Ueda Castle. In 1585, Ieyasu Tokugawa attacked Ueda Castle and attacked Maruko Castle when he lost. When Tokugawa's Yorada Suwa began attacking on August 15, Maruko Sanzaemon, who is considered to be the head of Maruko's then, defends with a few soldiers. The next day Masayuki Sanada's artillery arrived and fired the Tokugawa army from behind. It seems that the Tokugawa army arsoned in the town and rejected the Sanada army, but eventually Maruko Castle did not fall.

The view from the observatory is good when you walk the mountain path

It was taken from the mountain trail of Yoda Castle on the opposite bank. February 28, 2021

Maruko Castle Ruins (685m/160m) Earthwork, Guo, Moat, Well Castle owner: Mr. Maruko Ueda City Koshigoe Walking course for local residents Arrived at Maruko Castle Ruins in about 15 minutes. The age of construction is uncertain. The lord of the castle is Maruko, who is the first to see Maruko in the 1st year of the 18th year. In the 10th year of the Tensho era, Mr. Maruko belonged to Mr. Sanada and became the stage of the "Battle of Maruko table" in the first Kamigawa battle, where the Sanada army and Tokugawa army clashed. Maruko Castle was built on an elongated hill between the Yoda River and the Uchimura River, and it is now maintained as Maruko Park. The main ridge of Maruko Castle is a peak with an elevation of 684.8m and a triangular point. During this period, it is almost a natural terrain and it is a separate castle. The part called Ninomaru has a higher observatory deck at the northern end and a wider curving ring to the south, where you can see the pier and the shallow Horikiri. The main ridge has two-tiered curving wheels on the north and south sides, and several curving belts on the west side. The northern ridge is a double Horikiri, and both Horikiri extend as a vertical moat on the west side. If you go down this vertical moat, you will reach the main residence (Tatsunoguchikan), which is said to be one of the residences. The date of construction is unknown. At the battle of Ueda Castle in 1585, when Masayuki Sanada attacked the Tokugawa Ieyasu army, Maruko Sanzaemon was the lord of the castle. After the Battle of Ueda Castle, Tokugawa's Yorada Suwa and Nagamori Okabe attacked and defended. It is now a historic park. Quote

Since it is a park, you can enjoy it with your family in the parking lot, toilet, water supply, playground equipment, promenade, and observatory on the hillside. Horikiri around the main enclosure even has an explanation board. (^-^ ゞ It seems that there are some medieval mansion ruins at the foot of the mountain

I went up from Maruko Park. The road was well maintained and it was easy to walk. The scenery was very good.

Superb view! Worth the hard climb! About 20 to 30 minutes from the park parking lot. Climbing from the park square is a short distance, but the road is dangerous. The risk is lower from the north side. In any case, there is a surprising degree of danger, so if you really want a spectacular view, you should be very careful when climbing.
