Ishigakibaru

The campaigns at Ishigakibaru took place on the island of Kyushu in which the Eastern Army led by Kanbei invaded the Western Army's stronghold to solidify their chances of victory at Sekigahara. Many former Toyotomi generals participated in these sieges against the Toyotomi loyalists. The Tachibana, Shimazu, as well as the Chōsokabe provided support for the Western Army resistance led by Yoshimune Otomo.

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 or the ally ranks will fall into disarray. Players must 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.
