Zombie Land Saga is set across Saga Prefecture, from a mansion modelled on a real Karatsu building and Saga Castle to the hot springs of Ureshino and the Alpino hall in Karatsu.
In the anime, seven legendary girls from different eras are revived as zombies to form an idol group and revive Saga. This route follows their gigs and haunts, with the real venues behind them. Some places are fictional or only approximate, as noted.
Japan's legendary prince Yamato Takeru rides east from Ise Grand Shrine, escapes a burning plain at Yaizu, crosses Ashigara Pass and meets his end on Mount Ibuki. His sword ends up at Atsuta Shrine in Nagoya.
The route follows the legend, told in the Kojiki and Nihon Shoki chronicles, through five places. Several are traditional identifications, so the pins mark shrines and mountains tied to the tale, not proven battlefields.
