I've been to Okinawa several times, and my first island hopping trip started near Naha. Tokashiki Island is definitely worth a visit, and the KKDAY package with boat and shuttle service is very convenient. My son and I didn't snorkel, but just hanging out on the beach was plenty. The nearby guesthouses also rent swimming rings, masks, life jackets, and more—everything you need. Walking down the beach to the large rocky area, I was pleasantly surprised to see hermit crabs.
There are a few Koreans and a mix of Chinese and Westerners. There are also a few Japanese people. The explanations are given in Japanese, but there are Korean, Chinese, and English translations written in a sketchbook-like material. The course goes around several times and lunch is provided (the taste is just okayㅜㅜ I ate it on the boat and got seasick so I drank it by mistake). The explanations are kind and there is a course that goes down to the deep sea. I went up early because my ears hurtㅜ They went down deep into the sea and took great pictures with a GoPro. If you are lucky, you can see sea turtles, but the water is deep so you can see them from far away.
