The Ryukyu Kingdom ruled Okinawa from Shuri Castle in Naha, and its story can still be walked at Nakijin, Zakimi and Katsuren castles and the Tamaudun royal tombs.
The route follows the kingdom from the three-principality era and Shō Hashi's unification in 1429, through a rival lord's fall in 1458, to the royal tombs of 1501. Most of these castle sites are ruins or reconstructions.
The Battle of Okinawa, fought from March to June 1945, ran from the Kerama Islands and the Kadena landing beaches to Shuri Castle and Mabuni Hill in the south of the island.
This route follows the land campaign through six places you can find on a map today, from the first landing to the Cornerstone of Peace, where the names of those who died on all sides are inscribed. Several sites are memorials, and the pins for the Kerama Islands and Kakazu Ridge are approximate.
In July 1853 four black warships anchored off Uraga and ended more than two centuries of Japanese seclusion. Within a year, Commodore Matthew Perry had delivered a president's letter, signed a treaty and opened two ports.
The route follows his two voyages: from the Ryukyu court at Shuri to Uraga, Kurihama, the treaty at Yokohama and the temples of Shimoda. Perry also visited Hakodate in 1854, but that stop is not included.
