I was just there a few days ago. Nothing particular noteworthy (better yet spiritual) stands out in my memory. Seems like the place is covered in some kind of a permanent tent or tarp or something like that. I couldn't get a good view of the temple. Maybe they're redoing something to the building. Well, a lot of people were here buying those Japanese Omamori amulets that most temples and shrines sell. There were tables of them set out and lots of people around scarfing them up. Either they were on sale or the place is some kind of outlet store/wholesaler for it. At the entrance, there are some monuments - one had a pretty good English description talking about the founder of some branch of karate. I don't know, it was my first stop in the morning and maybe I just wasn't awake enough or receptive for whatever goes on here. I walked away with passionate indifference.

It has some particular significance for Okinawan spirituality and is in a convinient location. They sell goshioncho (御朱印帳) here.
