Omi Village in Kubara is Jin's childhood home and the seat of Clan Sakai. You return in Act 2 to recover your father's armor, and the village is central to the final tale.
Jin comes back for his father's Sakai Clan Armor and finds the village untouched by the invasion. Only Yuriko and a caretaker named Taichi are left.
The village is empty after The Proud Do Not Endure. In the last tale, Shimura says Omi has been given to another clan, and he and Jin duel in the Sakai cemetery by Kazumasa's grave.
Jin SakaiJin Sakai is the samurai you play in Ghost of Tsushima and the Iki Island expansion. He is Lord Shimura's nephew and the last lord of Clan Sakai. After the Mongol landing he trades the samurai code for stealth and fear, and the people start calling him the Ghost.
Kazumasa SakaiLord Kazumasa Sakai is Jin's father and the former head of Clan Sakai. He died in a raider ambush on Iki Island while Jin watched, frozen with fear. That memory haunts Jin through the whole game and drives the Iki Island expansion.Izuhara
Izuhara is the southern region of Tsushima and the first one you explore in Act 1. It is where you rescue Lord Shimura from Castle Kaneda, meet most of your allies and learn the stealth tools that turn Jin into the Ghost.
Kishibe Village
Kishibe Village is a Mongol-occupied settlement in Otsuna, near Omi Village. You can free it on its own or during the story tale Ghosts from the Past.
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.
