Guide
Takashima Castle is a historic fortress located in Suwa City, Nagano Prefecture. It was once famously called the "Floating Castle of Suwa" because it was surrounded by the waters and wetlands of Lake Suwa, making it appear as if the castle were floating on the lake. Today, the site is developed as Takashima Park, featuring a reconstructed castle keep, stone walls, and moats. It is officially recognized as one of the "100 Famous Japanese Castles." The sight of the castle harmonizing with the surrounding natural environment makes it a quintessential symbol of Japan's historical landscapes.
The history of Takashima Castle dates back to the construction of fortifications by the Suwa clan during the medieval period. Later, it was rebuilt in its current location by Hineno Takayoshi and served as a vital stronghold for the Suwa Clan during the Edo period. The castle follows a "Renkaku-shiki" (linear) layout, where the San-no-maru, Ni-no-maru, and Honmaru enclosures are arranged in a straight line from north to south. Due to the soft ground near the shores of Lake Suwa, advanced engineering techniques were required to construct the stone walls. While many structures were lost following the abolition of the feudal system during the Meiji Restoration, the site now beautifully preserves both historical remains and reconstructed buildings.
The most significant attraction is the reconstructed castle keep, completed in 1970. This reinforced concrete structure serves as a museum, housing various exhibits regarding the castle's architecture and historical documents. The surrounding stone walls and moats still evoke the atmosphere of a former water-fortress. You can also find remnants of other structures, such as castle gates that were relocated to nearby temples like Honwa-ji and Joko-ji. The layout of the castle, designed to utilize the natural terrain through the Renkaku-shiki style, can be fully appreciated through the onsite displays.
Takashima Castle offers a different face to visitors in every season. The contrast between the stone walls, moats, and the surrounding vegetation is particularly stunning during the spring cherry blossom season and the autumn foliage season. Visiting during bright daylight hours allows for a clear view of the intricate details of the castle keep and the structure of the moats. Because the surrounding landscape changes with the seasons, each visit offers a unique visual experience.
Inside the castle keep's museum, visitors can learn about the history of Japanese castle architecture and the technical skills used in the past. You can discover fascinating historical details, such as why certain materials like cypress bark (kakibuki) were used instead of traditional tiles. Walking through the expansive Takashima Park allows you to grasp the physical scale and layout of the fortress. The surrounding scenery also provides insight into the history of the castle town and the relocated structures of nearby temples.
The area around Takashima Castle is dotted with several historical spots. You can feel the history of the former castle town of Kami-Suwa-shuku and visit nearby temples like Onsen-ji and Joko-ji, which house relocated castle structures. Since Lake Suwa is also very close, you can easily plan a route that combines the history of the castle with the natural beauty of the lake. The site is highly accessible via JR Kami-Suwa Station, making it easy to travel by train.
As the park contains stone walls, steps, and unpaved paths, comfortable walking shoes are highly recommended. Please prepare cash (310 JPY) for the admission fee. English-language information is available via a downloadable PDF leaflet, making it accessible for international travelers. Photography is generally permitted, but please check the rules for specific exhibits or areas.
