Kanto Castles

📍 Tokyo — Kanto

The largest castle ever built in Japan — now the Emperor's residence — where you can walk the foundations of the tower that ruled a nation for 265 years.

📍 Kanagawa — Kanto

The castle that Hideyoshi could not storm — famous less for its tower than for the legendary city-swallowing earthworks and the indecisive council that became a Japanese proverb.

📍 Saitama — Kanto

The last honmaru palace in the Kanto region and the castle town that became 'Little Edo' — Kawagoe rewards visitors who want castle life beyond just the tower.

📍 Saitama — Kanto

The Floating Castle that refused to sink — Oshi's 1590 water siege is one of the great underdog stories in Japanese military history.

📍 Chiba — Kanto

The castle that hosts Japan's largest history museum — walk ancient earthwork moats, then explore 10,000 years of Japanese history without leaving the castle grounds.

📍 Ibaraki — Kanto

Home of Japan's most famous fictitious traveler and the intellectual dynasty that helped end the shogunate — a castle of ideas more than stone.

The Satomi clan's coastal stronghold — best known as the setting that inspired Japan's longest classical novel, the 106-volume Hakkenden epic.

📍 Gunma — Kanto

The Kanto mountain castle that shouldn't have stone walls but does — an unexpected masonry fortress with water cisterns at the summit of a Gunma mountain.

📍 Gunma — Kanto

Sanada clan cliff fortress above three river gorges — one of Sengoku Japan's most dramatic natural defensive positions, destroyed by Tokugawa political fiat in 1681.

📍 Chiba — Kanto

The domain castle of Honda Tadakatsu — Japan's most famous undefeated samurai, who fought 57 battles without receiving a wound.

📍 Kanagawa — Kanto

Where Hideyoshi built a complete fortress in secret behind a mountain, then revealed it overnight to psychologically break the last castle that had never been conquered.

The birthplace of the Ashikaga Shogunate — a living temple inside a perfectly preserved 12th-century warrior manor moat, where Japan's second shogunate had its origin.

📍 Saitama — Kanto

The cliff-top fortress that defeated Takeda Shingen — Hachigata's natural river defenses are among the best in the Kanto region, now preserved in an excellent earthworks park.

📍 Tochigi — Kanto

The castle that beat Uesugi Kenshin nine times — and now hosts dozens of cats among its mossy stone walls and mountain shrine.

📍 Tokyo — Kanto

Tokyo's forgotten mountain fortress — where thousands died in a single day when Hideyoshi came for the last holdouts of the Hojo clan.

📍 Gunma — Kanto

The castle that resisted Takeda Shingen and Uesugi Kenshin — a vast earthwork system in Gunma preserving the memory of the Nagano clan's remarkable defense.

📍 Tokyo — Kanto

Tokyo's forgotten mountain fortress — the Hojo clan's earthwork masterpiece held off Takeda Shingen, and its ridge-cut moats remain dramatic 450 years after abandonment.

A lake-floating castle with two genuine Edo-period survivors — modest ruins, but the Lake Kasumigaura setting tells the whole defensive story.

📍 Ibaraki — Kanto

A medieval mountain castle above one of Japan's three great Inari shrines, with boulder-integrated stone walls and a famous spring azalea garden.

Ota Dokan's swamp fortress — a water-island defense on the flat Kanto Plain that held Hideyoshi's army at bay longer than most.

The Sanada clan's ultimate mountain refuge — one of Sengoku Japan's most dramatically positioned castles, now famous for sea-of-clouds autumn photography.

📍 Saitama — Kanto

Zero visual drama, maximum scholarly significance — Sugiyama is the 'textbook castle' that only the most serious castle enthusiast will truly appreciate.

The tiny castle whose seizure triggered Hideyoshi's Odawara campaign — Japan's unification started here on a narrow Gunma ridgeline in 1589.

📍 Tokyo — Kanto

A 14th-century medieval castle ruin hidden in a central Tokyo residential neighborhood — five minutes from a tram stop, a world away from modern urban reality.
