Minato's Safe Houses

Minato Namikaze had a safe house somewhere outside Konohagakure which he utilized 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 safe house was destroyed by the Nine-Tailed Demon Fox when Minato teleported the beast there to seal it in his newborn son Naruto Uzumaki.
