Kakegawa Castle was a familiar landmark for travelers on the old Tokaido, the major route connecting the samurai-era government center in Edo (Tokyo) with the capital, Kyoto. Along this highway, travelers would pass through 53 checkpoints and post towns, stopping only at government-approved inns.
Kakegawa served as the 26th stop from Edo's Nihonbashi, the renowned bridge used as the reference point for measuring national distances. Kakegawa also served as a stop on the salt road running through Shinano Province (Nagano Prefecture). Overseeing this important post town, the salt route, and the strategically vital Tokaido route was Kakegawa Castle. In fact, the Tokaido crossed through the eastern section of the castle grounds, requiring travelers to cross a moat, enter the castle grounds, and then exit again, ensuring the route's security.
The initial version of Kakegawa Castle was built around the 1470s by Asahina Yasuhiro, a samurai under the powerful Imagawa clan of Suruga (Shizuoka Prefecture). Following the fall of the Imagawa clan at the Battle of Okehazama in 1560 at the hands of Oda Nobunaga, the lands of the Imagawa were divided between the rival Tokugawa and Takeda clans. Although Kakegawa was within Takeda territory, it was peacefully surrendered to the Tokugawa in 1568. Tokugawa Ieyasu controlled the castle until 1590, when Toyotomi Hideyoshi, having gained control of most of the nation, forced Ieyasu to accept domains in the Kanto region, based in Edo, and cede his other provinces.
Kakegawa was then commanded by Toyotomi retainer Yamanouchi Kazutoyo (Yamauchi Katsutomo), who completely redesigned and improved the castle. The remaining stone walls, moats, and the basic layout of the castle date from Yamanouchi’s time. The keep built by Yamanouchi was destroyed by an earthquake in 1604 and was not rebuilt until 1621.
The Battle of Sekigahara in 1600 saw control of the nation fall into the hands of the victorious Tokugawa Ieyasu. Yamanouchi was transferred to Kochi in Shikoku, and Hisamatsu Sadakatsu, Tokugawa Ieyasu’s half-brother, became the first in a line of mostly Tokugawa-related lords who ruled until 1746.The Ota clan then held the fortress for seven generations until the end of the Edo period.
The castle was well maintained until the great Ansei Earthquakes of 1854 caused extensive damage. Apart from the keep, many of the buildings were repaired by 1861, and following the end of Tokugawa rule, were used as regional administrative offices.
The original Otemon guardhouse still stands, although in a different location, as Kakegawa City Hall was built on the site of the Otemon Yagura, which was relocated to its current position. Six gates once guarded the central precinct. The Otemon has been reconstructed, although about 50 meters west of its original position. The third gate, Fuki-no-Mon, is now part of Enman-ji Temple. The gate was transferred there at the beginning of the Meiji Period but was lowered by 70 cm. Likewise, the Ote-San-Mon was given to the nearby Yusan-ji Temple in Fukuroi, where it remains.
The Ni-no-Maru Goten, a simple yet elegant palace on the flatlands below the hill, remains intact to this day. Built by Daimyo Ota Sukekatsu after the 1854 earthquake and before the collapse of the shogunate, it is among the last truly original Edo period castle structures and is registered as a National Important Property. The land and a substantial amount of money to finance the castle's rebuilding were left to the city by a wealthy resident. With local donations, the keep, some yagura watchtowers, and walled sections were rebuilt in 1994 in the traditional manner, making Kakegawa the first post-war castle to be constructed in wood.

Wakayama Castle

Wakayama Castle was built in 1585, when Toyotomi Hideyoshi ordered his uterine brother, Hashiba (Toyotomi) Hidenaga, to construct a castle on the site of the recently captured Ota Castle. The purpose of this construction was to secure control over the likewise newly conquered Province of Kii. Following an already established tradition, Hidenaga entrusted the project to his castle-building expert, Todo Takatora. Takatora carefully inspected the future castle site, personally drew up several designs, created a model of the planned castle, and took part in the work of laying out the grounds (nawabari). For the construction he brought in more than 10,000 workers and completed the large-scale project within a single year, which was considered extremely fast by the standards of the time.
Toyama Castle

Toyama Castle is located almost in the very center of the former province of Etchū and is surrounded by a wide plain with a large number of rivers. The very first castle on the banks of the Jinzu River was built in 1543 by Jimbo Nagamoto. The Jimbo clan were vassals of the Hatakeyama clan and governed the western part of Etchū Province. The eastern part of the province belonged to their rivals, the Shiina clan, who were also Hatakeyama vassals. Beginning in the 15th century, the influence of the ancient Hatakeyama clan gradually weakened, and as a result, the Jimbo and the Shiina fought constant wars for control of the province. Meanwhile, the forces of the Ikkō-ikki movement periodically intervened, helping first one side and then the other.
Takada Castle

During the Sengoku period, the lands where Takada Castle would later be built were part of Echigo Province and were controlled by the Uesugi clan.
Kishiwada Castle

The celebrated 14th-century military commander Kusunoki Masashige (1294–1336), who owned extensive lands south of what is now the city of Osaka, ordered one of his vassals, Kishiwada Osamu, to build a fortified residence. This order was carried out around 1336. These fortifications became the first structures on the site of what would later become Kishiwada Castle. From the beginning, the castle stood in a strategically important location—roughly halfway between the cities of Wakayama and Osaka, south of the key port of Sakai. Because of this position, it changed hands several times during periods of warfare.
Kaminoyama Castle

Kamino-yama Castle stood at the center of an important logistics hub, in the middle of the Yonezawa Plain, which served as the gateway to the western part of the Tohoku region. Roads connecting the Aizu, Fukushima, and Yamagata areas intersected here.
Imabari Castle

Tōdō Takatora (1556–1630) served at different times as a vassal of several famous clans—Azai, Oda, Toyotomi, and Tokugawa. He took part in the Battle of Anegawa (1570), the Battle of Shizugatake (1583), the invasions of Kyushu and Korea, the Sekigahara campaign (1600), and the Siege of Osaka (1614–1615).
Iwakuni Castle

Kikkawa Hiroie (1561–1625) was the grandson of the famous daimyo Mori Motonari and a vassal of the Mori clan. Under Mori Terumoto, he fought in both Korean campaigns and took part in the defense of Ulsan Castle. During the Battle of Sekigahara, Hiroie stood with his 3,000-man force on the side of the Western Coalition; however, even before the battle began, he sent Tokugawa Ieyasu a secret message stating that he did not intend to fight Tokugawa’s troops. As a result of his inaction, 15,000 soldiers under Mori Hidemoto were also unable to enter the battle, since Hiroie blocked their path.
Gujo Hachiman Castle

Gujo Hachiman Castle is located on 350-meter Mount Hachiman, near the confluence of the Yoshidagawa and Kodaragava rivers, and not far from the Nagaragawa River. During the Sengoku period, this area was of great strategic importance: it stood at a key crossroads of routes connecting Mino Province in the south with the Sea of Japan in the north, and Hida Province in the east with Echizen Province in the west.
