In Naha, one of the wildest experiences is to go to Kokusai St. and walk around all the restaurants and retail shops and bars and pottery stores and... and... and... then there is The Underground. Enter here and you'll find a myriad of places to see and shop and look and gawk.
One of the most interesting is the Fish (and Pork) market. We'll spend this visual week there so you can get a "feel" for this amazing experience... check out this myriad of fish and shellfish on display. You can probably find any kind of fish you could ever imagine... except maybe, Nemo.
