He takes a short nap, then decides to check whether his currency is acceptable. It does turn out to be such, so he gets himself a permanent warming spell (and a permanent cooling spell which also protects against sunburn), a leather harness he can attach his sword to (they couldn't find a scabbard that would fit the sword's peculiar shape), a pair of sandals, and something that looks sort of like a combination of a skirt and a loincloth in a local style, blue on the sides and black on the front with bronze medals sewn onto the skirt itself and hanging from its edge. It goes down to his knees, loose and light enough that it doesn't really interfere with movement, which is fairly relevant—if he doesn't miss his guess there's going to be a lot of physical fighting here. It's different from his usual style, but you know, what are the odds he'd find exactly the same kind of thing he used to wear back in Zanarkand? And he can get used to this.
The shopkeep gave him an odd look when he asked for other possible stuff to wear, and that was how he found out that they have cheap and easy laundry magic so most people have One Outfit that they always wear, which strikes him as pretty damn odd but he supposes if laundry is cheaper and faster than actually making clothes by enough this makes any amount of sense. Another world, and all that. He supposes his style will henceforth be This Here Skirt And Sandals.

And now he... doesn't really know what to do next. The trek back to the beach is not so short that he can go and do anything there and then return, because it'll be sundown soonish and he has a mighty suspicion that these people who have no electricity are going to want to leave for their boat trip at dawn. Also he doesn't actually know the way back; he could follow the river and it would probably eventually lead him to the ocean but he didn't pay enough attention to remember whether there were any rivers close to the beach, and he might end up stranded who knows where. So he has a couple of hours to kill until he has to sleep again.
Maybe he could go look for the protagonist, get to know him before the actual boat trip. That sounds like a reasonable idea.
After asking around, no one knows for sure where Zei is but a reasonable guess is the nearby lake; he's known to enjoy going there to relax, and Yevon knows he needs some relaxation after getting his first aeon. Tōkan gets directions and sets off.
