Why dive here
With 262+ marine species recorded in the area - including bull sharks, humpback whales, seahorses, sea turtles and clownfish - Senma Dragon Hole offers some of Okinawa Main Island's richest cave diving.
Senma Dragon Hole is one of those Okinawa sites that really delivers on its name. You’ll find it carved into the coastline, a shallow cave that’s easily accessible, making it a good pick for newer divers keen to try something a little different. We typically see schools of sweepers inside, darting in and out of the light shafts that pierce the cavern ceiling on a sunny day. The rock formations here are pretty interesting too, with a real sense of being inside the earth without ever feeling too enclosed. Visibility can vary, but generally, it’s a calm, straightforward dive.
