We have arranged the services for professional divers that Aquabase has cultivated so far for general tourists, and we offer a tour that specializes in snorkeling, where you can visit 2-3 spots of Yabiji, each with its own unique highlights, with sea turtle spots and secret coral spots scattered around, in a 3-hour tour. From November 2024, we will start offering a bath towel rental service. All the troublesome preparations for sea play can be prepared at the store, making it easier to participate in the Yabiji tour.
