One of the largest castle complexes in western Japan; its greatest mystery is whether its keep was ever built at all

Fukuoka Castle was built by Kuroda Nagamasa — son of the strategic genius Kuroda Kanbei — and at its peak covered a vast hilltop in the center of the city. With 47 turrets and multiple enclosures, it was one of the largest castle complexes in western Japan. But it holds a riddle no historian has fully resolved: was a keep (tenshukaku) ever actually built? Some records suggest the site for a five-story keep was prepared but never completed. Others claim it was built but demolished. The mystery persists. Today the ruins sit in Maizuru Park, famous for 1,000 cherry trees. Archaeological excavations since 1987 have revealed an even older structure beneath — the Kōrokan, a 7th-century guesthouse for foreign diplomats, showing this hilltop has been the center of international exchange for 1,400 years.

The mountain fortress that directly inspired Akira Kurosawa's "The Hidden Fortress" — which in turn inspired George Lucas to create Star Wars

Most visitors come to Akizuki for the cherry blossom tunnel on Sugi-no-Baba Street — 500 meters of pale pink canopy in late March, considered one of Fukuoka's most beautiful spring scenes. But Akizuki holds a surprise for film lovers: the mountain fortress of Mt. Kōshō above the town directly inspired Akira Kurosawa's 1958 film "The Hidden Fortress." In the film, the last survivors of the fictional "Akizuki clan" — a princess and her general — must cross enemy territory disguised as peasants. George Lucas has explicitly cited "The Hidden Fortress" as a key inspiration for Star Wars: the princess became Princess Leia, the two bickering peasants became C-3PO and R2-D2, and the samurai general became Obi-Wan Kenobi. The "Akizuki clan" in Kurosawa's film is named after this real place. Standing in the town, it is easy to see what Kurosawa saw.

A castle town built entirely on water — 470km of canals still navigable today; home of Japan's most famous female warlord

Yanagawa's canals were not built for aesthetics — they were built for war. The original Kamachi clan ringed their castle with an intricate network of waterways to create an "impregnable" island fortress in the wetlands of southern Fukuoka. The castle itself no longer exists, but the canals remain: 470 kilometers of them, still navigable by traditional flat-bottomed donko-bune boats. The canal tour is Yanagawa's signature experience — willow trees trailing in the water, old merchant warehouses reflected in the canal, the boatwoman's pole finding the bottom. What most visitors don't know is that Yanagawa Castle was home to one of the most remarkable figures in Sengoku Japan: Tachibana Ginchiyo, a woman who became the head of her clan at age 6 and commanded its armies in battle.

Gateway between Honshu and Kyushu; site of Miyamoto Musashi's most famous non-duel — the duel he refused to fight

Kokura Castle stands at the strategic chokepoint between Honshu and Kyushu — whoever held it controlled movement across the Kanmon Strait. Built in 1602 by Hosokawa Tadaoki (the same Hosokawa who completed Nakatsu Castle and later patronized Miyamoto Musashi), it was considered one of the finest castles in Kyushu during the Edo period. Its most famous episode, however, involves an absence rather than a battle: when Miyamoto Musashi arrived for his legendary duel with Sasaki Kojiro at Funajima Island (now Ganryujima) near Kokura in 1612, his legendary lateness — arriving hours after the appointed time — is still debated. Did he arrive late to unsettle Kojiro? Was it the tide? Or was it a final moment of doubt from an undefeated man? The duel lasted seconds. Kojiro died. Musashi never fought another formal duel.
