Takeda Castle

Takeda Castle Ruins are the remains of a mountain castle located in Asago City, Hyogo Prefecture, built atop the summit of Kogeyama at an elevation of 353.7 meters. It is a historic castle said to have been constructed during the Kakitsu era (1441–1444) by Yamana Sōzen, the Shugo of Tajima Province, and later governed by the Ōtagaki clan under his control. Because the shape of the entire mountain resembles a tiger lying down, it is also known as “Torafusujō” or “Kōjō” (“Tiger Lying Castle”).

The greatest feature of Takeda Castle Ruins is its magnificent stone walls spread across the entire mountaintop. With a vast layout extending roughly 400 meters north to south and 100 meters east to west, the site consists of the main keep platform, Honmaru, Ninomaru, Sannomaru, South Senjō, North Senjō, Hanayashiki, and other areas arranged along the ridgeline. As a mountain castle ruin, it is exceptionally well preserved and is known as a valuable remnant that conveys the structure of the time to the present day. Much of the remaining stonework and layout were developed by Akamatsu Hirohide in the late Sengoku period.

Historically, the castle fell in 1580 during Hashiba Hideyoshi’s campaign in Tajima Province. It then came under the Toyotomi regime, and Akamatsu Hirohide eventually carried out the castle’s development as lord. However, after the Battle of Sekigahara in 1600, Hirohide, who had sided with the Western Army, was ordered to commit seppuku, and the castle lost its lord and was abandoned. For more than 400 years since then, only the stone walls have remained, with the castle never rebuilt.

Takeda Castle Ruins are also known as the “Castle in the Sky” and the “Machu Picchu of Japan,” and are famous nationwide for their dreamlike scenery. Especially on early mornings from autumn to early winter (late September to early December), the morning mist that forms in the basin creates a sea of clouds, through which the castle ruins appear to float—a truly breathtaking sight. Large day-night temperature differences and clear, cold mornings are ideal conditions for sea-of-cloud formation, with November being a particularly favorable time.

This mystical landscape has captivated many photographers and tourists, and photos taken since the 2000s were featured in newspapers and magazines, sparking a nationwide “Castle in the Sky” boom.

Representative spots for enjoying the sea of clouds and the spectacular view of Takeda Castle Ruins include not only the ruins themselves but also Ritsuunkyo, a natural park on the opposite side of the valley. Ritsuunkyo has several observation decks, and from the First Observation Deck in particular, you can take in a panoramic view of Takeda Castle Ruins floating in the sea of clouds. From Tōwa Pass to the northwest, you can enjoy a fantastical silhouette of the ruins against the backlight, and its easy car access is another appeal. In addition, from the keep platform within the ruins, you can enjoy a powerful close-up view overlooking South Senjō.

When visiting, early-morning mountain walking is required, so carrying a flashlight or headlamp, comfortable walking shoes, and cold-weather clothing is recommended. Admission hours vary by season, but during the sea-of-cloud season, entry is possible from around 5:00 a.m. Admission is 500 yen, and the site is closed for the winter season from January to February.

Takeda Castle Ruins are also appealing for the way they display different beauty throughout the four seasons. In spring, cherry blossoms color the stone walls; in summer, the site is enveloped in greenery; in autumn, you can enjoy the sea of clouds and autumn foliage; and in winter, snow-covered scenery offers a different expression each time you visit. In recognition of its scenery and historical value, it was selected as one of Japan’s 100 Famous Castles. Furthermore, in 2012 it was designated as a “Sacred Site of Love,” making it a popular destination for couples as well.

Takeda Castle Ruins are a rare place where you can experience the spectacular scenery created by nature and nearly 600 years of history at the same time. Standing atop the stone walls, you may feel as if you have stepped back in time into the Sengoku period, offering visitors a deep sense of emotion and historical romance.
