Samurai Warriors
In Samurai Warriors 3, the Eastern Army version of Ishigaki Plains is featured in Kanbei and Kiyomasa's stories. The battlefield shares the same map as Kasai-Osaki, but uses different textures. Although Kanbei is the official commander, Kiyomasa must also survive the battle or the ally ranks will fall into disarray. Players should quickly infiltrate the stone labyrinth while facing the enemy officers within the vicinity to face Yoshihiro and Motochika. Their defeat triggers Yoshimune and Ginchiyo's charge, with reinforcements led Muneshige. For the Western side, it is only available in Ginchiyo's story. Players need to repel Kiyomasa and Masanori's overwhelming charge, allowing Motochika, Yoshihiro, and Muneshige to arrive as reinforcements to defeat Kanbei.
