The aquarium, of course, is mandatory to visit if you arrived in Okinawa) huge beautiful aquariums, a separate marine museum, of course the size of this structure is impressive) you can feed stingrays and touch starfish) the only problem is a huge number of people 😅 I was there on Monday, there were literally a sea of people. There is a themed cafe, which is better to queue in advance, but the food there is simple and European, apparently for the Japanese this fast food is like something festive) there is a large store of all sorts of things from key chains and shoppers, to toys and dishes. Outside there is a large landscaped beach, very clean, free, with changing rooms, shower and toilet, so you can come with a swimsuit.
An incredible place. Going to Okinawa, located a thousand kilometers out to sea, is worth it just because of him. The main memory is a huge, incredibly large aquarium, probably the size of a good concert hall. There are huge whale sharks in it, leisurely flying manta sharks... And you are in the glass niche of this aquarium and watch them float right above you!
Well, in general, a rich exposition, of course. I remember the aquarium with manatees, made in two levels: you can look from the surface of the water, or go down and stand nose to nose with a huge animal sleeping at the bottom of a deep tank.
