Go shopping. Kokusai Street and Heiwa Dori are the heart of shopping in Naha. Kokusai (which means international) Street is the main retail street in Naha. Heiwa Dori branches off from Kokusai St. and is one of the entrances to the Ichiba or the old market. It's easy and fun to get lost among the tiny shops and stalls of a time before Walmart and Ikea. Whether it's a $10,000 kimono or a pig's ear, you can get it here.
