Diving Manza Blue Hole—also known as the “Dream Hole”—is one of the most epic underwater spots in Okinawa.
It’s just off Cape Manzamo in Onna Village, and the dive starts with a narrow tunnel around 15–20 feet (5–6 meters) down. You drop into a big chamber about 80–100 feet deep (25–30 meters), then swim out through this glowing blue exit that people say looks like Pikachu’s face.
It’s wild.
Inside the cave, you’ll see everything from lobsters to lionfish, and sometimes there’s a shimmering cloud of glassfish hanging at the exit.
Outside, there’s a good chance of spotting turtles, reef sharks, or even eagle rays. It’s deep and dramatic—definitely for more experienced divers who are comfortable with overhead environments and good buoyancy.
Most shops require Advanced Open Water and at least 30 dives under your belt. They usually run two or three boat dives a day out of Seragaki Port.
Besides the Dream Hole, there are other great sites nearby too—like the Mini Dream Hole, Toilet Bowl (yep, that’s the real name), and sandy critter-filled spots perfect for macro lovers.
If you’re into caves and tunnels, this one’s a must.
