The Siege of Odawara of 1590 was fought at Odawara Castle in Kanagawa, with Toyotomi Hideyoshi's one-night castle at Ishigakiyama and Hōjō outposts at Hachigata, Hachiōji and Oshi.
Hideyoshi's army surrounded the Hōjō capital while other forces took its castles across the region one by one. This route follows the campaign through five castle sites, from the siege to the last holdouts, and most can still be visited as parks or ruins.
Date Masamune, the One-Eyed Dragon, was born at Yonezawa Castle and ended his life as lord of Sendai. This route follows him through Yonezawa, Aizu, Iwadeyama, Sendai Castle, Zuigan-ji at Matsushima and his mausoleum at Zuihoden.
It covers the castles he took, rebuilt or founded between 1584 and 1636, and the temple and tomb that survive him. Most of the original buildings are gone, so several stops are sites or rebuilds.
Admiral Yi Sun-sin fought Japan's invasion fleets in 1592–1598 along Korea's south coast, from his base at Yeosu to Okpo, Hansan Island, the Myeongnyang Strait and the Noryang Strait, where he died in the last major battle.
The route follows five places in order: the headquarters, the first victory, the crane-wing trap, the strait where 13 ships faced a far larger fleet, and the final night. Several pins mark waters or harbours rather than exact battle spots.
