Why go
Kerama Islands sits in the East China Sea off Japan, a wall and reef system where dives drop from shallow tops into deeper water. Dives run to 40 m with around 35 m visibility, gentle currents and sea temperatures of 22–29°C. Marine highlights include turtles, manta rays and clear blue water. Best season is Apr–Oct, typically reached by boat. A good choice for divers with some experience. Open Water certification is sufficient for most sites here. With dives to 40 m, comfort at depth is recommended.

Boat
Loved it. Getting there by boat was easy, and the water was a comfortable 22–29°C.
Solid choice for intermediate divers. With a range down to 40 m there's room to work without pushing boundaries.
Wasn't sure what to expect, and it completely won me over.
