Japan has a rich history of castles, and the classic Japanese castles that we know today date back to as early as the Sengoku period (1467-1603). Japanese castles were originally built as fortresses for military defense and later evolved into status symbols to house the wealthy daimyos, or feudal lords. These castles were constructed primarily of wood and stone, and are well known for the design of the tenshu, or the main keep, which is multi-storied and typically features curved roofs. While there were once thousands of castles in Japan, only somewhere over one hundred remain today due to war and natural disasters. Many of the existing Japanese castles are complete reconstructions or heavily reconstructed versions of damaged castles, and there are only twelve original construction castles in Japan today. Today I wanted to introduce some of Japan’s most unique castles.
