What is Misaka Castle?: A Historic Mountain Castle in Fujikawaguchiko Town
Misaka Castle is a mountain castle from the Sengoku period located on the border of Fujikawaguchiko Town and Fuefuki City in Minamitsuru District, Yamanashi Prefecture. Built on the Misaka Pass at an altitude of approximately 1,300 meters, this castle was an important military base controlling a crucial transportation hub connecting Kai Province (present-day Yamanashi Prefecture) and Suruga Province (present-day Shizuoka Prefecture).
The Fujikawaguchiko Town side is designated as a town-designated historical site, and the Fuefuki City side is designated as a city-designated historical site, making it a valuable historical heritage site that conveys the characteristics of a mountain castle from the Sengoku period. Located with a close view of Mount Fuji, remnants such as earthworks and baileys from that time can still be seen today.
History of Misaka Castle: From the Takeda Clan to the Tensho-Jingo War
Construction and Role in the Sengoku Period
The exact construction date of Misaka Castle is unknown, but it is believed to have been built by the Kai Takeda clan during the Sengoku period. The Takeda clan, a powerful daimyo based in Kai Province, expanded their influence and built castles throughout their territory for administrative purposes.
The Misaka Pass was a crucial transportation route from Kai Province through the foothills of Mount Fuji to Suruga Province. Controlling this pass was extremely important both militarily and economically. Misaka Castle functioned as a frontline base protecting this pass, playing a vital role in the Takeda clan’s territorial defense system.
The Fall of the Takeda Clan and the Era of Oda Nobunaga
In 1582 (Tensho 10), Takeda Katsuyori was attacked by the combined forces of Oda Nobunaga and Tokugawa Ieyasu, leading to the downfall of the Takeda clan. It is believed that Misaka Castle was also caught in the fighting during this Oda-Tokugawa invasion of Takeda territory. After the fall of the Takeda clan, Kai Province came under the control of Oda Nobunaga, and Kawajiri Hidetaka was appointed as the lord of Kai Province. However, when Oda Nobunaga was killed by Akechi Mitsuhide in the Honnoji Incident in June of the same year, Kai Province once again entered a period of turmoil.
The Tensho-Jingo War and the Battle for Misaka Castle
After the Honnoji Incident, Tokugawa Ieyasu and Hojo Ujimasa (Later Hojo clan) fiercely fought over Kai Province. This was the Tensho-Jingo War. In this conflict, Misaka Castle reappeared on the historical stage as an important strategic base.
The Hojo clan was a Sengoku daimyo based in Sagami Province (present-day Kanagawa Prefecture) and sought to expand into Kai Province. Hojo Ujitada (younger brother of Hojo Ujimasa) led the Hojo army across the Misaka Pass and attempted to invade Kai Province. Misaka Castle is believed to have been used as a frontline base by the Hojo army.
Meanwhile, Tokugawa Ieyasu also aimed to conquer Kai Province, and the two sides clashed fiercely. Ultimately, a peace agreement was reached between Tokugawa Ieyasu and Hojo Ujimasa, and Kai Province became Tokugawa territory. However, Misaka Castle remains a significant site in Japanese Sengoku period history as one of the important stages of the Tensho-Jingo War.
After the Edo Period
After the Tensho-Jingo War, when Kai Province came under the control of Tokugawa Ieyasu, it is believed that Misaka Castle ceased to function as a military base. During the Edo period, it was abandoned and spent a quiet time as a mountain overlooking the mountain pass.

Basic Structure of the Castle
Misaka Castle is a typical mountain castle, characterized by defensive structures that skillfully utilize the natural terrain. Multiple baileys (flat sections) are arranged on both sides of the pass, each surrounded by earthen ramparts.
The central part of the castle is located near the highest point of the Misaka Pass, allowing for surveillance of the surrounding area. The remains extend east and west along the pass, with defensive structures built on both the Fuefuki City and Fujikawaguchiko Town sides.
Major Remains
