Lord Shimura's Camp is the samurai war camp in Kubara where your uncle gathers his army to retake Castle Shimura. You meet your allies here before A Reckoning in Blood and The Fate of Tsushima.
Shimura plans the attack on his castle with Jin and the allies you recruited across Act 2. He learns that Ryuzo's men at Fort Koyasan could flank him, which sets up A Reckoning in Blood.
A Reckoning in BloodA Reckoning in Blood is the Act 2 tale where Jin raids Fort Koyasan to settle things with Ryuzo before the attack on Castle Shimura. It is one of the darkest tales in the story, so finish any prep you want first.
The Fate of TsushimaThe Fate of Tsushima is the Act 2 tale that starts the assault on Castle Shimura alongside the shogun's reinforcements under Lord Oga. It is a long tale and a partial point of no return, so wrap up side work before you confirm.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.
Fort Koyasan
Fort Koyasan is a Toyotama fortification where Ryuzo's men gather to flank Lord Shimura's army. You attack it in A Reckoning in Blood before the siege of Castle Shimura.
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.
