If Naruto were to become Tsuchikage, he would first have to adapt to the different culture of Iwagakure. The people there are known for their earth - style jutsu and tough exteriors. Naruto, with his sunny disposition, would try to break through that. He might hold festivals like the ones in Konoha to boost morale. In terms of defense, he'd use his strategic mind. Since he has faced many powerful foes, he would know how to fortify Iwagakure against potential threats. And his connection with the tailed beasts could also be an asset. He could potentially use that knowledge to find new sources of power within Iwagakure related to the earth element.
