The dive
Between ~5 and 15 m hangs a cloudy brackish layer (halocline), all year and worst in March–May, with visibility down to ~2 m. Deeper and in the tunnel it is clearer.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
Two dolines on Shimoji's west coast, linked to each other and to the sea. Boat dive from the cliff with a local dive centre: through the tunnel into the seaward pond. Requirements per centre: Advanced Open Water and 50+ logged dives (Sun Island), some centres 100+; no discover-scuba guests. Whether you surface in the pond differs per centre.
