Kawanakajima

The Battle of Kawanakajima (川中島の戦い, Kawanakajima no Tatakai) refers to the military conflicts between Shingen and Kenshin in the northern Shinano Province. The games focus on their oft romanticized fourth battle at Hachimanbara, Nagano Prefecture, also known as The Battle of Hachimanbara (八幡原の戦い). In the first game, it is followed by an imaginary fifth confrontation.

Samurai Warriors
This battle acts as the beginning for several Takeda or Uesugi related generals. In Samurai Warriors, the main focus at the start of the battle is Shingen's pincer attack. The Takeda army separates into two parties, one distracts the Uesugi army and the other circles from the east to attack Kenshin's rear. The ambush party is lead by Yukimura and Kunoichi while the defensive unit is composed of Shingen and the rest of his vassals. As the secondary unit draws closer to their objective, a heavy fog descends upon the battlefield. The visibility on the map improves once the secondary unit reaches their target. Kenshin, however, has already abandoned the position and charges the Takeda main camp. After the rivals clash their weapons, Shingen continues to defend his position. Yukimura's party hurry to their lord's aid by rushing back to Hachimanbara. Once they arrive, they can continue their pincer and surround Kenshin as he flees towards Zenkoji.

During Kenshin's scenario, he has the option to quickly dispatch both the central units as well as Yukimura, thus foiling Shingen's plan. He can also occupy Shingen's escape point, Kaizu Castle, and defend his own from being fallen to the enemy. When he defeats one of Shingen's valued generals, Kansuke Yamamoto, enemy morale plummets and Kenshin gains a winning edge. Choosing to charge towards his rival's position also gives the same effect.

The rivals meet here once more in Kenshin's upper path scenario and Shingen's lower path scenario. Their tactics focus on quickly taking their enemy's respective castle on the field. Both men must also defeat Hanzō to protect their main camp; Shingen must additionally defeat Keiji for a similar reason. If the young warriors for either side (Kanetsugu and Yukimura) are defeated, both warlords commence a lone charge for a one-on-one showdown.

The stage serves a similar purpose in Samurai Warriors 2. As opposed to centering on one particular plan, the battle is filled with several complementary tactics.
