The latest Naruto episode to be released was episode 192.
As we all know, episode 192 was also a filler. In this epiode, Ino and Naruto are sent on a mission. Ino is suposibly the spitting image of a princess whose having weight control problems interfere with her arranged marriage. Ino's job is to be a duplicate of the princess and to make the date with the prince a sucessful one, making sure that he likes the princess. In the end, it turned out that the fat prince liked fat women, so when the real princess was revealed by mistake, he asked her hand in marriage, making Ino and Naruto's mission kind of pointless.
