"How did Paleolithic people arrive at such remote islands as Okinawa? What tools and strategies did they use?"

This keeps blowing my mind. I'd make an awful Paleolithic human.Well... that's what sets homo sapiens (allegedly) sapiens apart from all others: our quest to explore, to see the other side of the hill.
The Austronesians/Polynesians did have maps in the form of stick charts.For example, the ancient Polynesian people had no maps, but they could travel almost the entire Pacific. There are a variety of signs on the ocean to know the right direction, such as visible land masses, heavenly bodies, swells, and winds. We learned parts of such techniques ourselves along the way.”
Neat. This reminds me of watching The Ra Expeditions (1972) in the theater as a kid, about sailing papyrus boats across the Atlantic - (wiki) https://en.wikipedia.org/wiki/Ra_(1972_film)
I actually don't think this is a widespread or quintessential urge. I think we chase resources and land, not curiosity.Well... that's what sets homo sapiens (allegedly) sapiens apart from all others: our quest to explore, to see the other side of the hill.
I don't know how likely it is but some cultural or religious form of "follow me to the promised land" would not be unprecedented. Lots of occurrences of that.As a proof of concept, this stands up pretty well.
Beyond that, I'm not convinced it answers many questions about the means of colonizing the region's islands. It feels like a people wouldn't just go paddling off into the distance without a better support system, or without knowing there was something to paddle out to. Both of which were provided in this example.
Since time would erase all traces of these things - especially as more time passed - it leaves doubts about how often this was done and under what circumstances. THAT it can be done seems evident. HOW it was done wasn't entirely answered by this. Of course, this was just a proof of concept. Not proof of how it was done.

Are you sure about that? The aggressive exploration of the ants invading my kitchen suggests otherwise. They are incredibly persistent, brave and continue to explore at great peril of their own demise from both physical affront and chemical warfare. And I do not even want to start on the intrepid adventures raccoons undertake in my back yard. Very clever and ambitious they are...Well... that's what sets homo sapiens (allegedly) sapiens apart from all others: our quest to explore, to see the other side of the hill.

Ever heard of survivor bias?This experiment points out the difficulty of the task, even with modern knowledge (geography, etc). However, the experimenters were lacking the training and cultural knowledge that would’ve been available to Paleolithic people.
For comparison imagine if a thousand years from now all knowledge of “sport” is lost, but archeologists discovered golf clubs and golf balls and tried to estimate how far and how accurately people could hit them. I’m betting no one would believe the skill attainable by even high level amateurs (let alone professional golfers).
Now imagine how much a society built around seafaring could do with just primitive navigation and boats, given what these researchers were able to do.
Looking at the specific geography on Google Maps (I'm not familiar with the area), it seems there are hills along the east coast of Taiwan well in excess of 1000m (over 1600m at the highest). From 1000m, the horizon is over 120 kms away - about the distance to Yonaguni, which is itself ~200m high. So it would be "fairly easy" for someone hiking in the hills of eastern Taiwan to look out at the horizon and see a dark smudge of an island. I've experienced that in San Diego - on a clear day you can see San Clemente Island (not the city) 70 miles offshore. The key is having a really clear day without the typical ocean haze, but it's pretty obvious once you've noticed it the first time - if the seeing conditions are good.In the case of islands only two days' paddling apart, that's not so hard. I mean, beyond just hoping that there might be, or noticing birds flying back to roost in the evening going in an unexpected direction, there's always going to be cases of "fisherman gets blown out to sea unexpectedly, catches sight of distant land, returns home after the wind dies down."
Note that shallow water offers a lot of opportunities for fishing, so there's a pretty strong incentive to go looking for islands.
Heyerdahl's hypothesis was rooted in cultural bias bordering on racism and has never really been taken seriously. But he also did some amazing things and did actively promote ideas that were in opposition to racism. So yeah. Great adventurer, sub-par scientist, someone I would have enjoyed drinking beer with for an evening. But mostly wrong about stuff.Neat.

I love the trend of scientists recreating / re-enacting what our ancestors did (or at least, the trend of reporting on it- I guess it's completely possible scientists have been doing this forever and I'm just learning about it more now).

Padding is very feasible if their simulation study is sufficient correct. The old current appears (Fig 2) to be in the 0.8 to 1.2 m/s range whereas the modern models are over 1.2 m/s. So these researchers would have easily done it given that they were able to do it under modern conditions.In the case of islands only two days' paddling apart, that's not so hard.

Also, given sea level at the time there would have been more landmass to spot and that land would have been higher relative to sea level. Sea level wouldn't have been as low as during the last glacial maximum but it still would have been much lower than today.Looking at the specific geography on Google Maps (I'm not familiar with the area), it seems there are hills along the east coast of Taiwan well in excess of 1000m (over 1600m at the highest).

So I'd expect someone out hiking in the mountains had seen it, and wondered "what's there? Let's go look!" The fact they didn't see the island from the boat (sea level) until the last few hours doesn't mean they didn't know the island was there the whole time - it just meant they couldn't use the island to navigate. It also probably means they could look back over their shoulder and see Taiwan the whole time - so that might give some comfort that "if this doesn't work, we turn back."
A key technology the Polynesians were using for open-ocean boats that we haven’t found evidence for in the Paleolithic (or even most of the Neolithic) is the outrigger. The stability makes a big difference in open-ocean use.The fact that the Polynesians traveled much of the Pacific with a similar level of technology sorta proves it's possible. Their craft were more advanced, catamarans with sails etc, but were still built with stone age technology. The fact that no masts or sails exist from this time period doesn't mean they didn't have them, more like they just didn't survive the 20,000 years?
This is a ~600 year old canoe recently discovered in NZ, so pre-European (and the use of metal).

..., or without knowing there was something to paddle out to.
The canoes of the pacific didn't start out that advanced. They became advanced by inquisitive humans trying to improve them. All it would take was one person thinking 'maybe we can make this voyage easier if we lash a bamboo raft to the side of the canoe to make it more stable'. The same goes for harnessing the wind; because paddling requires effort.The fact that the Polynesians traveled much of the Pacific with a similar level of technology sorta proves it's possible.

Technologies have to be developed in concert, though. A canoe with a sail and no outrigger in the open ocean is just begging to be capsized, for instance.The canoes of the pacific didn't start out that advanced.

I agree that there is no reason to think masts and sails didn't exist at that time. They would have been made of wood or bamboo (strong, light, flexible), and woven plant fiber. Those materials don't hold up well over time in wet humid areas.
I have to admit to suffering Survivor bias. Stupid TV program aimed at stupid people...Ever heard of survivor bias?
Point well taken... But yeah, all a shotgun will do to an elephant is make him angry and get you trampled completely.I couldn't feed myself in the wilderness even if had been given a loaded shotgun to shoot a dormant elephant at close distance.
