Based on the concept of "Suimui", Shurijo Castle Park preserves land, water quality, plant life, and other features of old capital. It is designed as a historical park where people can sense community.
Okinawa's kitchen is the place for meats, fishes and pickled goods. On the second floor are the various food shops. You can purchase ingredients in the 1st floor and bring it to the 2nd floor to have them cook it for you. (Cooking fee is separate)
One of my favorite things to do here is karaoke. Here in Okinawa City you have your choice of the karaoke box or the karaoke bar. I prefer the bar because it affords a greater opportunity to mingle and get to know the people. My favorite karaoke spot is a place called the Prince. It is run by the sweetest 70+ year old Okinawan woman. It is open every night (except Monday) from 8pm until whenever, usually until 6am. Her drinks are not overpriced and there are free snacks that can include sashimi, fried squid, and various other tempura. To sing, it costs a dollar or 100 yen per song and she has everything from Patsy Cline to Boys to Men to Aerosmith. The customers are a mix of American's, Okinawans and Japanese mainland tourists. Be prepared to sing for a crowd on some nights. A good singing voice is highly appreciated and may even get you free drinks.
Take a ferry from Naha port to Tokashiki Island during the whale watching season. The day I went it was sunny and warm out and we saw lots of whales.
