Advanced Okinawa wall dive with a rocky shore entry.
Advanced Okinawa wall dive with a rocky shore entry.
Toilet Bowl is an advanced Onna, Okinawa wall dive known for its sharp limestone bowl and dramatic drop into open water. The route mixes a rocky shore entry, a steep wall, and cavern-like pockets that reward calm buoyancy and tidy teamwork. It is best on settled days, because wind, swell, and current can change the whole site quickly. Sharks, turtles, and dense reef life are possible along the wall.

Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Sharp limestone, changing current, and a tricky exit make tight buoyancy and a planned turnaround point important.
Access Restrictions
Experienced divers only; the rocky shore entry and exit are not a casual self-guided setup.
Community notes to help plan your visit.
Scuba Diving
Plan a controlled shore entry, then stay tight on buoyancy as the wall drops away and the bowl opens into the reef edge. The site rewards confident route management more than casual cruising.
Freediving
Only for highly confident freedivers on very calm days. The rocky entry, changing water movement, and exit make it a poor casual freedive site.
Snorkeling
Not a casual snorkel site. The entry, exit, and changing water movement make it better for divers than for surface-only visits.
