Minato's Safe Houses

Minato Namikaze had at least two safe houses somewhere on the outskirts of Konohagakure which he utilised in case of an emergency. Inside, he kept his equipment including cloaks, and Flying Thunder God Kunai amongst other items so he could teleport to and from the village in case something happened.

The first safe house was destroyed by a combination of Obito planting Explosive Tags on Naruto and Minato jumping to it to get it away from Kushina, himself, and Naruto. The second was destroyed the Nine-Tailed Demon Fox when Minato teleported the beast there to seal it in his newborn son Naruto Uzumaki.
