Diving School Marea Shinsaibashi

Set in the heart of Osaka City, Diving School Marea Shinsaibashi is a PADI 5-Star IDC that carries divers all the way from their very first breath underwater to professional certification. With four PADI Instructors on the team, it's a place built as much for curious first-timers as for those with their sights set on an instructor rating.

Courses and facilities

The center runs the full PADI pathway, including PADI Scuba Diving, PADI Freediving, and PADI First Aid (EFR) training. What sets Marea apart is its own onsite swimming pool, paired with an onsite classroom and air-conditioned comfort, so you can build skills and confidence in a calm, controlled setting before heading to open water.

Divers looking to go further will find Nitrox available, along with equipment sales and travel services all under one roof. Instruction is offered in Japanese, making it a natural home base for anyone starting out or leveling up in the Osaka diving scene.
