This hot spring spa in Chita District is located in what is now Ono-cho, Tokoname City, and Mandara Temple sent a persimmon as a token of sympathy to Tadayoshi, who was practicing the hot spring bath, and a thank-you note in response remains. In 1607, Tadayoshi left for Edo, his illness still unresolved. There, he passed away at the age of 28 on March 5, a few days after meeting with Ieyasu and Hidetada.

Matsudaira Tadayoshi had no children, and his younger brother Yoshinao Tokugawa inherited the remaining Kiyosu domain. In addition, the Tojo Matsudaira family, which Tadayoshi inherited, became extinct during Tadayoshi's generation, but it was inherited by Yoshinao Tokugawa's family and incorporated into the Owari domain.
When the Owari Tokugawa family moved from Kiyosu to Nagoya, they preserved the treasures handled by Tadayoshi Matsudaira, and they are now stored at the Tokugawa Art Museum in Aichi Prefecture.

Matsudaira Tadayoshi and Ii Naomasa camp ruins

The Battle of Sekigahara, which took place in 1600, involved approximately 170,000 soldiers from the Eastern and Western armies. However, the battle itself ended in half a day. It is said that about 8,000 people died in this half-day battle.
It is said that Tokugawa Ieyasu, who won the Battle of Sekigahara, had his head examined after the battle, buried many of the bodies here, and erected the East Kubizuka and Nishikubizuka.
The East Kubizuka is located very close to JR Sekigahara Station, but in the east corner of Kubizuka, in Oaza Sekigahara, Sekigahara-machi, Fuwa-gun, Gifu Prefecture, there is the ``Remains of the camp of Tadayoshi Matsudaira and Naomasa Ii''.
This was the first battle for Tokugawa Ieyasu's fourth son, Matsudaira Tadayoshi. At the beginning of the Battle of Sekigahara, Ii Naomasa of the Tokugawa clan wanted to make his son-in-law, Tadayoshi, who was the first in the battle, do some good, so he led a gun troop out on a reconnaissance mission. On the way, he was discovered and interrogated by Saizo Kani, the advance commander of Masanori Fukushima of the Eastern Army, but he managed to shake off his restraints and proceed to Sekigahara. It is said that the battle began when they fired guns at the army where Hideie Ukita was present.

Matsudaira Tadayoshi's Grave Site, Shokoin

This happened when Matsudaira Tadayoshi was given a territory of 100,000 koku centered around Oshi Castle by his father, Tokugawa Ieyasu.
In order to mourn the memory of his mother, Tsune Saigo (in name: Hodaiin), he performed Mantan Gendo and rebuilt Shogaku-ji Temple, which was located in the castle town of Oshijo.
Later, when Tadayoshi was transferred to Kiyosu Castle, he moved the three temples that had been located in the castle town of Oshi Castle to Kiyosu in 1603. One of the temples that was moved was Shogakuji.
After Matsudaira Tadayoshi died in Edo in 1607, it became Tadayoshi's family temple.
In 1610, there was a large movement of temples from Kiyosu to Nagoya, including the castle grounds (Kyosu-koshi), and the name of the temple was changed from Tadayoshi's name to Shoko-in.

Oshijo (Oshijo) ruled by Tadayoshi Matsudaira

Oshi Castle was a castle located in Shinobu, Saitama District, Musashi Province (currently Gyoda City, Saitama Prefecture). It is currently a historic site designated by Saitama Prefecture. It is said that around the 10th year of Bunmei (1478), the Narita clan exterminated the Shinobi clan, who were the local people of Musashi Province, and built Oshi Castle.

It is said that during the Kanto subjugation carried out by Toyotomi Hideyoshi in 1590, 3,000 people including around 500 samurai and ashigaru, as well as casual soldiers, farmers, and townspeople barricaded themselves in Oshi Castle (Battle of Oshi Castle). ).
It is said that Ishida Mitsunari became the commander-in-chief of the Toyotomi clan, and that Yoshitsugu Otani, Masaie Nagatsuka, Masayuki Sanada, and others participated. At this time, Ishida Mitsunari built a 28km-long Ishida embankment and flooded it with water, but the castle did not fall and Odawara Castle surrendered first, so it was opened afterwards.

After Tokugawa Ieyasu entered the Kanto region, Tadayoshi Matsudaira was appointed and it became the Oshi clan's 100,000 koku domain office. After Tadayoshi moved to the Seishu domain, the feudal lords of the feudal lords were transferred, but Oshijo Castle was developed and flourished as a backroad post station on the Nakasendo road and a distribution route for water transportation on the Tone River system.

In the late Edo period, the area became famous as a production area for tabi socks.
In the Meiji period, most of the structures at Oshi Castle were removed and the remaining castle ruins were developed as a park. Gyoda City Honmaru Baseball Stadium was built in Shinobu Park in 1949, but it was later relocated, and the Gyoda City Folk Museum was built on the site in 1988, and it has become familiar to citizens.

Kiyosu Castle, the final resting place of Tadayoshi

Kiyosu Castle was a castle located in Kiyosu, Kasugai District, Owari Province (present-day Ichiba, Kiyosu City, Aichi Prefecture).
Located in the center of Owari Province, it is a strategic point connecting the Tokaido, Ise Kaido, and Nakasendo roads.
In 1405, the castle was built by Yoshishige Shiba, the feudal lord of Owari Province. In 1478, the guardian post was relocated and Kiyosu Castle became the center of Owari Province.
As time passed, it became the main castle of the Oda family, the shugo who ruled over the lower four districts of Owari Province.

Oda Nobunaga made Kiyosu Castle his residence during the unification of Owari Province.
After the Battle of Sekigahara, Tokugawa Ieyasu's fourth son Matsudaira Tadayoshi entered the domain and became the foundation of the Kiyosu domain, but Tadayoshi died of an illness from the wounds he received at the Battle of Sekigahara. Therefore, in 1607, Ieyasu's ninth son, Yoshinao Tokugawa, entered the castle.

However, in 1609, Tokugawa Ieyasu ordered the castle to be moved from Kiyosu Castle to Nagoya Castle. When Nagoya Castle, built by the feudal lords of western Japan, was completed, the town that had been located at Kiyosu Castle was moved to Nagoya Castle in 1610, and from then on Nagoya Castle became the center of Owari Province. ). This is where the Owari Tokugawa family, one of the three Tokugawa families, begins.

Currently, most of the ruins of Kiyosu Castle have been destroyed by fire, and the area is divided into the Tokaido Main Line and the Tokaido Shinkansen. All that remains is the earthworks of the main enclosure.
A mock castle tower made of reinforced concrete was built in 1989 in the Kiyosu Regional Cultural Plaza adjacent to Kiyosu Castle.
In addition, there is a bronze statue of Nobunaga in Kiyosu Park to the south of the Tokaido Main Line, and a monument honoring the Kiyosu Castle Ruins in Kiyosu Castle Ruins Park to the north, making it a relaxing place for citizens.

Across Cheongju

This story takes place after Tadayoshi Matsudaira passed away in 1607. The center of Owari Province has long been Seishu, ruled by Tadayoshi. However, Cheongshu suffers from frequent flooding downstream of the Shonai River, and the area was liquefied by the Tensho Earthquake in 1586.

Furthermore, after the Battle of Sekigahara, the Tokugawa clan had to compete with the Toyotomi clan in Osaka. Kiyosu Castle was considered as one of the bases to oppose the Toyotomi family, but Kiyosu Castle had the disadvantage that it was too small to garrison a large number of soldiers.
Therefore, when Tokugawa Ieyasu ordered Tokugawa Yoshinao to rule after Tadayoshi, he had him build a new castle on the Atsuta Plateau, Nagoya Castle. The construction of the castle was a large-scale project that required many of the feudal lords of the Western region. Furthermore, a moat will be excavated around Nagoya Castle and a new town will be created.

In this way, most of Cheongju was relocated to Nagoya, with not only vassals and townspeople from the Cheongju castle town, but also shrines and temples being relocated. This is called Cheongju-goe. For this reason, being a resident of the former Cheongshu region, having lived through the region, has now become a status symbolizing the tradition and formality of Nagoya.
