Japanese Garden is a south-side Grand Cayman reef dive reached by boat or the local mooring network, with a shallow coral slope that opens into tunnels and cavern-like swim-throughs. The site is known for staghorn and elkhorn coral growth, schools of silversides, and fish such as tarpon, jacks, and Bermuda chubs. It suits divers who want a shallow, scenic reef with overhead shape, bright fish life, and enough structure to reward a slow, careful pass.
