Kashin is depicted as an elderly man, roughly in their 60s-70s, and Jiraiya's child would not be in their 60s-70s, however Jiraiya himself would be, assuming he's still alive. This would make sense given that Ao, a Shinobi originally thought dead, has joined Kara, it wouldn't be far fetched to believe Kashin would also be a Shinobi thought dead that is alive and has joined Kara. It would also make sense as Orochimaru stated "You either die a hero or live long enough to see yourself become a villain" when saving Tsunade, and that had Jiraiya not died there's a chance he'd have ended up like the previous Orochimaru, as he had changed to become an ally of the Leaf instead of being opposed to it, meaning that no matter what, it was unlikely the original Sannin would ever all be allies again. Also, Kashin Koji not only stated to be related in some fashion to the Land of Fire, but also has an interest in Boruto, just as Jiraiya would if he were still alive. However that would be hard to use as pure evidence by itself, and is only icing on the cake, if you will.

Their physical similarities are undeniable, as Sarutobii2 had stated, they both have the same markings under their eyes, as well as they both possess the same eyes. We also need to take into account that Jiraiya's throat was crushed by Pain just prior to his death, and we haven't seen Kashin's throat yet. The moment we see his throat either all wrinkled up sort of like Obito's face or covered by scientific technology will be the moment we can confirm whether he's Jiraiya or not. http://prntscr.com/ivvm5h http://prntscr.com/ivvmfl The only real issues with this theory is how did the Kara organization find Jiraiya's body? It had sunk to the bottom of the ocean where it would have been crushed. Also, why would Jiraiya join Kara? During his death he clearly chose to accept his demise as a ninja, allowing Naruto to take over and continue to "write the sequel" to Jiraiya's story. If he were still alive he'd have seen first hand Naruto not only perfect Sage Mode, but also befriend Kurama, put an end to the Fourth Great Ninja War, bring peace to the world, and finally become Hokage, even if it were from the shadows. None of these events would have turned Jiraiya against The Leaf, making this theory very hard to believe without further evidence or a good reason for him to betray The Leaf.
