Of course, the REAL settlers didn't know that Okinawa even existed, much less where it was located.
30,000 years ago would have been near the coldest point of the last Ice Age.
Sea level would have been much lower, and, possibly, intermediate islands would have appeared between Taiwan and Okinawa.
During that period, it would not surprise me if people could have almost walked, or at least floated, from Korea and Sakhalin to Japan.
However, the oldest human bones ever found in Japan are only about 15,000 years old, so maybe this entire effort was just a recreational fantasy.
I want to know how Hawaii got settled. The Polynesians couldn't have island hopped to get there. Whoever did get there by accident wouldn't have known how to get back home to pick up some women; and then try to get back. Survival along the way would be a big issue.

Rather impossible to replicate an “ imagined/hypothetical “ sea migration. Now if it actually happened, then it can be replicated.
I think man floated long before we think they could float, But how did they follow the route of the vessel and know it got off track without onboard GPS?
