Shakushain's War (1669) was the Ainu uprising against the Matsumae clan of Japan, fought between Shinhidaka, Matsumae Castle and Kunnui in Hokkaido.
The route follows the revolt from the feud on the Shibechari River to the mediation at Matsumae, the fighting at Kunnui and the leader's death at Piypok. It ends with the Shakushain statue in Shinhidaka. Several sites are approximate and are marked as such.
Ghost of Yōtei follows Atsu, a wandering mercenary who returns to Ezo — modern-day Hokkaido — in 1603 to hunt down the Yōtei Six, the band led by the samurai lord Nariaki Saito who slaughtered her family sixteen years earlier. Her revenge carries her across an island modelled on Hokkaido, from the grasslands at Mount Yōtei's foot to the frozen north and the Matsumae clan's castle in the south.
This route follows the game's regions and their real counterparts: the Yotei Grasslands around Lake Shikotsu, the Ishikari Plain, the Ainu country of the Nayoro Wilds, the Kitsune's Teshio Ridge, and the Tokachi Range, with Mount Yōtei and Matsumae Castle as its fixed points.
