I just booked a trip in April to Okinawa via United with ANA codeshares to OKA from NRT. Will I need to go through immigration at NRT? Is there a *A lounge on the domestic side if I do have to transit through immigration? I have a few hours between the flights and would enjoy the chance to relax. Also, would be interested in any comments or suggestions for Okinawa. I will be traveling solo and on a budget so no rental cars or fancy resorts. I am an experienced traveler and love Japan (but don't speak much Japanese). I like nature, culture and some walks on a beautiful beach. I'd like to take some day trips to other islands. Don't want to visit military monuments or enter the Amerika town stuff. And what about those habu snakes - am I likely to see one?
