Now here is a fun thing Pam and Shelia showed me.

I wasn't aware that this seems to be the biggest tourist attraction on Okinawa until I googled it.

We walked around there for 3 hours. The views from the top have to be the best on Okinawa I have seen so far. As for the altar and the monk protecting the spirits; no evidence was found on our excursion. We did however run into a bunch of guys that were trying to scare us, but weren't that scary at all.

Direction: 

out of Foster Shoppette Gate, go straight and follow the signs towards Nakagusuku Castle. Park in the parking lot for the castle, pay 300 yen entrance fee, then follow the road to the right.
