Historical fact shows that Ryukyu Kingdom centered in this castle lasted over 500 years independent from main land regime, maybe, due to geographical separation. You can imagine it from world wide map, if available. Trade over Asian region and diplomatic practices with China played a great role in forming Ryukyu culture. Imported Thailand rice gave birth to awamori distilled from it. Ryukyu dance reflects inferiority in relation with China.
Sefa Utaki, the sacred place believed to be created by goddess of Okinawa, had a view point toward Kudaka island also sacred. There was nothing in particular for me except triangular shaped stone tunnel naturally (I am not sure) eroded. The whole area is a world heritage.
The third visit place, theme park for cultural experience, was just so so. We returned back to Nago a little earlier; We dove into awamori pool earlier, too. Another ex-JOCVs joined dinner with us.
