What's Naruto without the great Jiraiya? And what's Jiraiya without his pervy-ness? Of course, Jiraiya has set up his own spas in Konohagakure as a place where people can relax (or a place for Jiraiya to peek at half naked girls). When visiting Jiraiya's spas, you can really sit down and kick back. You may get a massage or take a dip in the spas.
Maybe this relaxation will give you some energy back or maybe you'll lose all your energy and become exhausted.
