The Kage Summit took place in the Land of Iron due to its security and neutrality, which it has prepared for by strengthening its guard. According to the Tsuchikage, Ōnoki, it has its own distinct culture, and there is "nothing fun about" meeting there. When Sasuke Uchiha attacked the summit, he was declared an international criminal for challenging the five great ninja villages and for meddling with the neutral Land of Iron. During the Fourth Shinobi World War, having realised it threatened the world, not just the Five Great Shinobi Countries, Mifune committed the Land of Iron and the samurai to aid the Five Great Shinobi Countries.
