Stone Mire Lookout is a Mongol-held post in the Old Kanazawa Marsh in Yarikawa. It is a minor territory, so clear it for iron and a small Legend bump while you are in the area.
Each minor territory you free in Toyotama counts toward the Good Riddance and Securing Sanctuary trophies and lifts more fog from the map.
Akashima Village
Akashima Village, in the prefecture of the same name, is the starting point of Norio's storyline. It has a full set of vendors, so it is a good resupply stop in western Toyotama.
Bamboo Forest Hot Spring
Bamboo Forest Hot Spring sits in Kushi, part of Toyotama, and is one of the game's 20 Hot Springs. Soak there once and Jin's maximum health goes up permanently.
Castle Shimura
Castle Shimura is the seat of Clan Shimura in Toyotama and the biggest battle of Act 2. Khotun Khan holds it after the invasion, and you retake it in The Fate of Tsushima alongside every ally you have gathered.
Cloud Ridge Shrine
Cloud Ridge Shrine is a Shinto shrine climb in Kushi, Toyotama, dedicated to Azumi-no-Isora, kami of the seashore. Reach the summit to earn the Charm of Azumi-no-Isora, a major charm: arrows make no sound on impact.
