Chūgoku

Chugoku was the western region of Japan mostly controlled by clans such as the Ouchi, Amago and Mori who kept sovereignty over the land when they surrendered to the Toyotomi and later bargained with the Tokugawa.

Role in games
In Samurai Warriors 2:Empires, Chugoku is a regional scenario and can be unified before starting on a main scenario. The year starts in 1561 so Motonari is still present.

In Samurai Warriors 3, this is Hanbei's final stage. He and Kanbei start by assaulting the southwest garrison in order to splinter Motonari's coalition. Once the Tachibana  duo are lured out, they can be defeated causing Motonari to shut off the main camp and southern offensive. Then Hanbei attempts to rendezvous with Hideyoshi in the north, who is under attack by Yoshihiro Shimazu and his ambush units. Once he helps Hideyoshi, they launch a final offensive breaking through to the main camp guarded by Motochika and defeating Motonari once and for all. In Hanbei's ending, Hanbei Kanbei and Motonari are discussing about tactics and the three arrows analogy. Yoshimoto Imagawa also reciprocates this battle in Sengoku Musou 3 Z: Special where he wants Motonari and the western clans to join him in kemari, to which an incensed Masamune Date provokes the western clans to rebel. It plays similarly to Hanbei's version other than these changes though. Motonari Mori also saves the Tachibana from an Oda-Shimazu co-ordinated attack in his story.
