Kushimoto draws divers with a striking range of site types: shallow reef dives accessible from shore, muck and wall dives reached by boat, and the deep technical wreck of the Stella Polaris. The Ornate Ghostpipefish and Mantis Shrimp are very commonly encountered, while the Green Sea Turtle and occasional Scalloped Hammerhead add larger-animal interest. Sites span beginner-friendly shallows through to advanced depths, meaning the area rewards divers at every experience level.

Yes, a good portion of the sites are rated for beginners. Shore-entry spots such as Noa Front Beach and Koza River Nukumi offer shallow, manageable conditions, and boat-access reefs like Glass World, Nakagurumi, and Bizen also cater to newer divers. Mild currents are noted at several of these sites, though surface surge should always be monitored.
Shore-entry sites such as Noa Front Beach and Marine Center Front are shallow and well-suited to building confidence or practising entries. Boat-access sites open up more varied terrain, from deep reef walls at Shimamawari to the muck dive at Ando no Hana and the advanced wreck of the Stella Polaris. A handful of sites, including Shirahama and the Kushimoto site itself, offer both entry options.
Reef diving is the most common site type, ranging from very shallow to moderately deep. Wall and cave formations appear at sites like Shimamawari, while muck diving is available at Ando no Hana. Wreck divers are catered for at Shirahama and, for technical divers, the deep Stella Polaris wreck. This variety means different diving styles can be pursued within the same region.
