Takamatsu Castle

Takamatsu Castle is a fortification in Tamamochō consisting of three nested water moats connected directly to the sea. The former main tower stood on an artificial island, while two smaller watchtowers still mark the outer defense lines today.

Ikoma Chikamasa ordered the construction of the fortress starting in 1588, transforming a port settlement into a military base. Later rulers expanded the complex until it was abandoned and partly dismantled in the 19th century.

The location by the sea gave the structure its alternate name Tamamo, meaning jewel of the water, a reference to the saltwater moats. Visitors today see mainly the two remaining turrets, which display the military skill of late 16th-century builders.

The former walls now lie within Tamamo Park, which opens in the morning and closes in the evening on weekdays. Those wishing to visit the two turrets should arrive early, as they are only accessible at certain times.

Fish from the sea, including sea bream, still live in the moats today, having adapted to the brackish water. These saltwater fortification ditches make the structure one of the three great water castles in the country.
