Kadena Marina Scuba & Sea

Okinawa Main Island, Japan

The team at Kadena Marina Scuba & Sea are a solid pick if you’re looking to dive Okinawa Main Island, especially if you’re stationed at Kadena Air Base. They're a long-standing operation, running since the 70s, which means they know these waters intimately. We love their focus on getting people certified, right up to instructor level with their 5-Star PADI IDC status, so it’s a great option for career divers or anyone wanting to go pro. They operate out of the Kadena Marina, which offers a straightforward setup. You’ll mostly be diving from their custom boats, heading out to sites like the famous Manza Dream Hole or some of the deeper wreck dives if you’re qualified. We’d suggest checking their daily schedule early, as popular trips fill up fast, particularly on weekends. The water clarity around Okinawa is generally excellent, often 20 metres plus, with plenty of reef fish and nudibranchs to spot. Look out for the resident green turtles, often seen grazing on the seagrass beds near quieter sites. While it can get busy in peak season, the boats are well-maintained and the staff keep things running smoothly.
