Opened now.

There is s local bus tgat goes and stop at different stops but it will takes a longtime. You can take the tour package We rented a car cos we wanted to go a few places andvthere were 4 of us so sharing cost be cheaper.

credit cards are no issue, I did see an ATM.

Google maps states it's a 15 minute drive from the port to the aquarium. If the aquarium is all you're seeking, I'd recommend a taxi. Unfortunately, the information on taxis in motobu is in Japanese. Good luck, it's a great aquarium!

Evening Ladies and Gentleman, Thank you kindly for your responses. The are both timely and detailed. In regards to the rental car, that is not a bad idea - since I am coming from Australia, we drive on the same side! There is currently a party of 2 or 3. The primary goal is to get from Naha to the Aquarium. the pineapple farm was not considered but will be now that you mentioned it. Since posting, I have done some more research and read on a website (and confirmed by one reply) of a bus that goes Express from Naha to the Aquarium - express 2 hours. At this point, this seems to be the most cost effective method. but i will definitely research the car rental. Thank you all.

the earliest you can go to the aquarium is at 8.30 according to the website. if you're only going to the aquarium, then spending 1-2 hours should be enough. You'll need more time to explore the whole expo tho, I'd say 4-5 hours, because they have other different galleries/attraction to see. I hope this helps:)
