The original castle was built by Hineno Takayoshi in 1598, with the keep added later to improve defensive positioning.
The nickname 'Floating Castle' derived from the 16th-century landscape where the marshy ground made the structure appear to hover above the lake.
Most of the original castle structures were dismantled during the Meiji Restoration in the 1870s.
The current three-tiered keep was built in 1970 based on historical drawings and records to preserve the site's identity.
The castle grounds are a popular location for cherry blossom viewing, specifically the weeping cherry trees which are over 100 years old.
The castle park features a specific area designed to show the footprint of the original Honmaru (main enclosure) layout.
Takashima Castle, known as the Floating Castle of Suwa, is a reconstructed 16th-century fortress situated in Nagano Prefecture. The current keep, rebuilt in 1970 using concrete, serves as a museum dedicated to local history and the castle's architectural legacy. Originally built on a marshy peninsula extending into Lake Suwa, the castle was historically surrounded by water on three sides, creating the illusion of floating. The site includes reconstructed stone walls, moats, and a park featuring cherry trees and Japanese gardens. Visitors can climb to the top floor of the keep for panoramic views of the Suwa Basin. The grounds also host a small museum gallery displaying samurai armor and historical documents. It is a designated municipal cultural asset.
