Kokura Castle — Sea Castle of the Straits

Kokura Castle (1602) stands at the mouth of the Murasaki River where it meets the Kanmon Strait, commanding views of both Shimonoseki and the industrial port that defines modern Kitakyushu. The reconstructed donjon (1959) rises five stories and contains a museum of local history. What distinguishes Kokura is the castle garden: a stroll garden surrounding the inner moat that has been replanted with the original plant palette specified in a 1688 document, making it an unusually historically grounded garden restoration.
