I loved this hotel for the quietness and the beauty of the location and for the kindness of the workers. Food is good and there is a wide choice. The building and the rooms maybe need a renewal, but if you're looking for a beautiful coral beach in Japan, this is a place where you have to go.
After having been in a luxurious hotel in Okinawa with a nice beach but the obligation to swim inside a small bay, closed by nets, Tokashiku has been a much better experience. Weather in mid August hasn't been very good, but snorkeling we saw 5 turtle just in front of the hotel and some reef rocks are easily reachable swimming. No jellyfish.
