Hello again! First off, great question because it’s always been vexing to me that the Sannin are all so skilled in this area, and yet fūinjutsu overall is such an underexplored, underexplained discipline in general. On the other hand, this gives us a lot of room to have fun with it (which I think I’ve yet to really make any specific headcanon for) so here we go!

What I’ll say first is that I’ve been waiting (I dunno why, because nothing was stopping me) for a reason to post this particular thing for so long now, but in regards to the origin of Jiraiya’s skill in fūinjutsu, I see Danzō being the one to introduce him to it and initially mentor him in his youth—I’d say from perhaps age 13 or 14, for a couple of years. And for this I’ve thought of a few main reasons it’d come about:

Plain and simple, Danzō is keen to piss off Hiruzen by snagging his students because he’s a salty and bitter old goat—and at this point Orochimaru isn’t quite on the cards, what with still comfortably being Hiruzen’s favourite. Meanwhile Jiraiya is underestimated and somehow, despite being the way he is, manages to fly under the radar a lot. The raw potential is there too, and it’s intriguing to him.

To expand on Jiraiya going unnoticed, he is also basically an orphan, with no parent present enough to ever interfere. This is an important factor that Danzō no doubt values in the early stages of building ROOT—and whatever its intentions were at the time, Danzō was not particularly a shady guy at this stage. He could scope out the talent relatively unbothered.

But young Jiraiya’s talents are definitely something he’s seeking out, knowing he eventually wishes to operate from the shadows, to have people who can blend in seamlessly—and Jiraiya, being so personable and capable of ‘acting natural’ to the most human degree, is a great candidate for such a job. Sometimes he barely even seems like a shinobi at all, and that’s a strength for a spy.

Of course, after a few infuriating years he learns that basically everything about Jiraiya as a person is fundamentally unsuited to the type of work he wishes to do through ROOT. What a waste of time, huh?

So with some degree of general mentorship and information-digging going on, Danzō offers some training across various specialties and thus discovers that Jiraiya has a natural flair for fūinjutsu. In fact, despite being a slow and steady learner in many other areas of shinobi discipline, he takes to this like a fish to water. Book-learned basic principles aside, I imagine it’s a very hands-on, intuitive skill that requires great creativity to expand on the knowledge already possessed—which is probably minimal, besides Danzō’s own and the previous Hokage’s contributions, based on how relatively early Konoha is in the whole ‘document everything’ game (relatively).

Needless to say, Jiraiya has the creativity down pat. He designed the seal to suppress the Kyūbi chakra, after all, and was even proficient enough to seal Amaterasu. Hell, his toad-themed jutsu in themselves are quite the exercise in creativity, so even though Jiraiya turned out to be no good for ROOT, he would use that brilliant(!) mind to go on to play a part in developing many seals commonly used among Konoha shinobi today.

His main forte, or at least the area of fūinjutsu where he really went wild, is the design of numerous paper/scroll/tag-based seals, lending to the general convenience of use for shinobi of all ranks. They’re easy to pack, carry and replicate which helped to ensure that units were more prepared than ever. Chiefly, sealing elemental jutsu (exemplified by sealing Itachi’s Amaterasu fire) and weapons within scrolls, along with chakra suppression, vocal silencing, paralyzing and tracking seals. He didn’t invent these manners of sealing by any stretch, but made the designs more... streamlined? Accessible? More simple to draw and execute, I imagine, being generally simpler himself and not so constrained by the rigid teachings of any given clan. 

As an aside—the reason he was so focused on sealing objects at all was so that he could bring Items He Should Not Have into Places They Weren’t Welcome, while being more difficult to notice doing so. Make of that what you will. (It’s booze-related because isn’t it always? Hell, maybe even some of that dank Myōbokuzan kush that the toads are blatantly always smoking in those fancy kiseru... am I joking? Who knows)

Anyway. His weapon seal would go on to inspire Tenten’s technique of sealing many weapons at once. Again by no means did he invent this technique, because this is Tenten’s baby (plus he’s no bukijutsu specialist!), but the theory had its basis within the seals he designed for simple and chakra-efficient storage of weaponry.

Again being very much geared towards paper and tag seals, much of Jiraiya’s training that was unique to Konan, along with combining toad oil/fire and paper, was teaching her fūinjutsu and brainstorming ideas to make her paper jutsu even more formidable and unpredictable than before. We of course see her using all those explosive tags in the fight with Obito, but I think Konan + paper seals doing all sorts of shit, releasing sealed jutsu and who knows what else... was a missed trick!

While I believe Mito definitely had influence on Jiraiya’s fūinjutsu, I think it was indirect, and any learnings of Uzumaki sealing will have been passed to Jiraiya through Kushina and/or what Minato learned through Kushina (who in turn learned most heavily from Mito). My reasoning for this is that as the first jinchūriki, Mito seemed to be far more isolated than later hosts would be, particularly in her older years—and I don’t see there being much inclination to share Uzumaki sealing secrets with someone with no ties to the clan. Kushina and Tsunade? Yes. Random little ragamuffin? Perhaps not.

... I’ve already rambled on a fair bit and think I’m out of proper ideas for now, so I’m just gonna take a moment to list some short/stupid fūinjutsu-related headcanon ideas now:

When he calls Orochimaru’s work sloppy that one time, it’s a big ol’ front. But he does still think this is one area where he’s better than Oro. Nyehhh.

Why yes, of course he has seals for sexual use! Climax-blocking, stamina refreshing, instant shibari (chakra or actual rope), all over stimulation via the mildest raiton contained in a seal? You bet!

Released a book of ‘prank seals’ including ‘poof the object into nonexistence’ and ‘release deluge of oil’ and ‘suddenly frog’ amongst many others. This book is illegal in most countries.

He once sealed (and I guess, technically stealed bwahahaha) a hotel jacuzzi when he was drunk, forgetting that there was no such thing as plumbing on the road, and its not exactly the same experience having to make all that hot water yourself

No appropriate place to piss? SEAL IT. BANISH IT. OR USE IT AGAINST YOUR WORST ENEMIES.

Once heroically sealed an entire town’s vermin infestation, forgot about it, then accidentally released it later. Is now barred from that ryokan, forever.

Has an entire scroll devoted to condoms

And another devoted to flavoured lube.

Not so stupid, but the need for rapid seal-drawing helped him to develop his ambidexterity to the point where you can barely tell what his dominant hand originally was (however he places down his left hand to summon in all early manga panels I remember at least, which indicates that as a child he signed it with his left hand).

He’s able to store Gerotora easily with a seal concealed in his throat. That’s why it’s so easy for him, not because of some other gutter-brained reason, honest.

He got really good at kanji through learning fūinjutsu. It arguably helped him along in his writing career—especially when writing more traditional style poetry.
