The History of Japanese Castles

Japanese castles’ history suggests that they were mainly constructed during the feudal period, beginning in the 15th century. They were to be used as fortresses in defense and power symbols. The Sengoku period, 1467-1603, was a period of perpetual warfare, and samurai and warlords constructed castles to defend their territories and regions. Castles were built strategically on high ground or moated for defense purposes. These buildings also embodied administrative centers with the status of their lords. 

The Edo period of 1603-1868 experienced Japan as a peaceful nation and castles as emblems of authority rather than as necessary places of military. Major events in the history of Japan were closely tied to the castles under Tokugawa Ieyasu as they controlled and defined Japan's political landscape.

Architecture of Castles in Japan

Japanese castles integrate strategic military design and aesthetic elegance. Most of the time, castles were built on raised ground or around moats, making them very defense-oriented. Their walls were stone, wooden framework, and very high towers to observe the surroundings. The most characteristic feature is the curved roofs, which often carry ornate decorations such as golden shachihoko (mythical tiger-fish creatures). 

Multiple layers, for example, had inner and outer baileys that allowed layering of defense while the residence of the ruler dwelled in the castle. Inside, in the complex set of gates, hidden passages, and steppes with staircases could be found multifunctional purposes; the main tower, or the donjon, often symbolized one of the main visible emblems of the lord's powers and rights and offered panoramic views for the surrounding zone.
