Living in Okinawa as an American

I have recently gotten a job offer to live in Okinawa for 2 years, working for the marine base on the island. I have heard the japanese have mixed feelings towards the Americans. And the only reason I like visiting countries is to experience the culture and to have kind interactions with native people. So for those how have lived in the island or have had extended visits, how had your experience been with the people?

Thanks!
