In the autumn of 1600 two armies met at Sekigahara to decide who would hold power after Toyotomi Hideyoshi. One day in the fog gave Tokugawa Ieyasu a decisive victory and put him on the road to the shogunate.
The route follows the campaign from the siege of Fushimi to the castles of Mino, the field of Sekigahara, the fall of Mitsunari's Sawayama and his burial in Kyoto, and ends at Edo Castle in 1603. Dates inside Japan's old calendar are labelled as such.
Nioh sends William Adams, a blond outsider who becomes Ieyasu's ally, through a dark-fantasy version of 1600: demons in the mud of Japan's civil wars, alchemist Edward Kelley behind them, and Tokugawa Ieyasu rising above it all. Its story is stitched onto real places, from a London prison to the battlefield that made the Tokugawa shoguns.
The route follows the main campaign and its last two expansions: the Tower of London, Kyoto, Sekigahara, then the Sanada-maru, Tennōji and Osaka Castle. The game is fantasy, so the map shows where its history happened, not where it was filmed or modelled.
