Tsutsujigasaki Castle (Tsutsujigasaki Yakata) served as the fortified residence of the last three generations of the Takeda clan and is located in the heart of Kofu, Yamanashi Prefecture, Japan. Unlike traditional Japanese castles, it was not referred to as a "castle" in Japanese, as the Takeda clan famously believed in relying on their warriors as their true fortifications, stating, "Make men your castle, men your walls, men your moats." Designated a National Historic Site in 1938, the ruins are now open to the public and house the Takeda Shrine, a Shinto shrine dedicated to the deified spirits of the Takeda clan.
The Takeda clan, a cadet branch of the Minamoto clan, gradually gained control of Kai Province during the late Heian period, originally fortifying themselves at Hakusan Castle and Yato Castle. By the Sengoku period, they held the position of shugo (governor) of Kai, and in 1519, Takeda Nobutora chose a central location in the province to establish a fortified residence and castle town. Unlike the common practice of building castles on mountains for defense, Nobutora constructed Tsutsujigasaki on a gentle slope in the Kofu Basin. To compensate for its exposed position, he also built a mountain fortress, Yogaiyama Castle, as a strategic backup stronghold.
The complex was one of the largest residential fortifications in eastern Japan during the Sengoku period. It featured two main enclosures surrounded by a combination of flooded and dry moats. The central enclosure housed the Takeda ruler’s private residence, while the western enclosure served as the administrative center, featuring heavily fortified "umadashi"-style gates. Additionally, two secondary enclosures, Miso-guruwa and Baio-guruwa, provided extra layers of defense. Today, the site retains some of its original water moats and minor stonework, with the Takeda Shrine, built in 1919, standing at its center. A museum, guarded by a stone Hello Kitty, is located to the right of the shrine.
Tsutsujigasaki remained Takeda Shingen’s primary residence after he overthrew his father in 1540. However, in 1581, his son, Takeda Katsuyori, moved to the newly constructed Shinpu Castle in Nirasaki. The Takeda clan met its downfall in 1582 when it was annihilated by the combined forces of Oda Nobunaga and Tokugawa Ieyasu. Following this, Nobunaga's general, Kawajiri Hidetaka, briefly ruled Kai Province from Tsutsujigasaki until Nobunaga’s assassination later that year. With the completion of Kofu Castle in 1594, Tsutsujigasaki was ultimately abandoned.

Amagasaki Castle
The founding year of Amagasaki Castle is traditionally considered to be 1617, when Toda Ujikané built his castle here, making it the administrative center of the Amagasaki Domain. However, as early as the Sengoku period, a fortress built by the Hosokawa clan already stood on this site. After the fall of Itami Castle in 1579, Araki Murashige—formerly a vassal of Oda Nobunaga who had rebelled against him—fled to this earlier castle.

Hiroshima Castle
Mōri Terumoto (1553–1625) was the grandson and rightful heir of the renowned Mōri Motonari. When Terumoto became the head of the Mōri clan in 1571, he inherited vast territories covering a large part of the San’in and San’yō regions in western Honshū. In addition, the Mōri clan possessed the largest and most technologically advanced naval fleet of its time.

Fukuyama Castle
After the defeat of Toyotomi Hideyori’s supporters in the Osaka Campaigns of 1614–1615, many clans in Japan still remained not fully loyal to the Tokugawa shogunate, especially in the western Chūgoku region. Mizuno Katsunari (1564–1651), a cousin of Tokugawa Ieyasu, became the first of the Tokugawa house’s close retainers, the so-called fudai daimyō, to be relocated to this strategically important area.

Tiba Castle
The founder of the Chiba clan is considered to be Chiba Tsunesige (1083–1180), who in 1126 moved his residence to the Inohana area and built a strongly fortified stronghold there. Although Tsunesige himself came from the Taira clan, the Chiba clan later supported Minamoto no Yoritomo, the future founder of the first shogunate.

Sunomata Castle
Oda Nobunaga, as part of his “final solution” to the conflict with the Saitō clan, conceived the construction of a fort in the Sunomata area, which was intended to serve as a forward base for an attack on Inabayama Castle (later renamed Gifu). Sunomata was a swampy area located between Ogaki Castle, a stronghold of the Oda clan, and Inabayama, the main fortress of the Saitō clan. Earlier attempts to build fortifications in this area, carried out by Oda generals Sakuma Nobumori and Shibata Katsuie, had all ended in failure. After that, the task was entrusted to the young vassal Kinoshita Tokichirō, who later became known as Toyotomi Hideyoshi.

Shibata Castle
The exact time when structures first appeared on the site of the present-day castle is unknown; however, it is generally believed that the first fortified buildings were constructed here during the Muromachi period, when these lands were controlled by the Shibata clan.

Okayama Castle
According to a number of accounts, the earliest fortifications on the site of present-day Okayama Castle appeared as early as the 14th century and were built by the Nawa clan. The Asahigawa River was used as a natural defensive barrier, protecting one side of the fortifications.
In the early 16th century, the Kanamitsu clan constructed a new castle here, which at the time was known as Ishiyama. In 1573, it came under the control of the Ukita clan, after which Ukita Naoie (1529–1582) launched large-scale reconstruction efforts. He did not live to see the work completed, and construction was continued by his son Hideie. -
Nagahama Castle
Hashiba, later known as Toyotomi Hideyoshi, received Odani Castle and the surrounding lands from Oda Nobunaga after the defeat of the Azai clan. However, Odani Castle was located high in the mountains, which made it poorly suited for the effective administration of the territory. For this reason, in 1575 Hideyoshi began constructing a new castle in the village of Imahama on the shore of Lake Biwa. Taking the character naga from Nobunaga’s name, he renamed both the village and the new castle Nagahama.
