Bitchu Takamatsu Castle
A flatland castle built on marshy ground in Okayama, famous as the site of Hashiba Hideyoshi's ingenious 1582 water flood siege. Hideyoshi diverted rivers to submerge the castle, and upon learning of Nobunaga's assassination, negotiated a quick surrender.

Bitchu Takamatsu Castle represents a rare example of a 16th-century flatland fortress built on marshy ground, located in what is now Okayama prefecture. Though only ruins remain today, this castle is historically significant as the site of one of military history's most innovative siege tactics, orchestrated by the brilliant commander Hashiba Hideyoshi in 1582.
Originally constructed during the Sengoku period, this flatland castle was built on difficult marshy terrain that provided both defensive challenges and advantages. Its isolation in wetlands made it a natural strongpoint, with water barriers serving as the primary defense system. The castle came to prominence during the final period of Japan's unification campaigns, when various regional powers struggled for dominance under warlord Oda Nobunaga.
The castle's historical importance centers on Hideyoshi's brilliant 1582 siege, where he diverted nearby rivers to completely submerge the castle and its defenders in a calculated display of military engineering prowess. Rather than launching conventional attacks, Hideyoshi employed hydraulic engineering to flood the fortress, demonstrating that military superiority could be achieved through innovation and logistics as much as through direct combat. The siege concluded dramatically when news arrived of Nobunaga's assassination, leading to rapid negotiations and the castle's surrender without excessive bloodshed.
Today, visitors can view the earthen foundations and landscaped remains of the fortress, though the structures themselves have long since disappeared. Interpretive signs explain the historical context and the engineering feat of Hideyoshi's water siege, making this site valuable for understanding both military history and the technical capabilities of the late Sengoku period. The site remains an important location for scholars and history enthusiasts interested in the dramatic final unification campaigns of Japan.
Bitchu Takamatsu Castle is recognized as one of Japan's second 100 castles as designated by the Japan Castle Foundation, a distinction that highlights its historical and architectural importance among the hundreds of castle sites across the country. As a flatland castle, its design reflects the defensive priorities and construction techniques of its era, with origins dating to 16th c. Visitors traveling to Okayama Prefecture can explore the site alongside other regional historical attractions.

Is It Original?
| Original keep still standing? | No — this castle is not among the twelve in Japan whose keep survives from the pre-modern period. Any tower here is a later reconstruction or the site is a ruin. |

The count of twelve surviving keeps is stated independently by the official sites of Matsue, Maruoka, Matsuyama and Bitchu Matsuyama (checked 2026-09-04). Each of the twelve carries its own source on its own page. The classification line below it is this site's own grouping, not an official designation. The designated properties below it come from the Agency for Cultural Affairs national database of designated cultural properties (国指定文化財等データベース), retrieved 2026-08-13. A missing line means no entry was found in that database — not that the property is undesignated.
