Toilet Bowl is a sharp limestone wall site in Onna with a rocky entry, current-sensitive exit, and payoff for calm buoyancy on settled days.
About Toilet Bowl
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.

Local Intel For Toilet Bowl
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.
