Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

Past many pillars you reach a dome-shaped space in Ryukyu limestone, dissolved by rainwater over a very long time, like a limestone cave.

Profile and sections

Past many pillars you reach a dome-shaped space in Ryukyu limestone, dissolved by rainwater over a very long time, like a limestone cave. Of Miyako's sites where you surface in a pond, the dive centre says this pond has by far the clearest water. Most holes here get the most light around noon, but this one opens to the east: the light is best around 10:00, in early autumn the sun pours in through the opening in the ceiling on the morning dive, and by early afternoon only a small part of the curtain of light is left.

The dive centre also calls it Mini Grotto.

Practical: the dive centre counts Mini Toriike among its easy sites (20%) and can dive it ~80% of the time.

Depth and profile
To 13 m: a long cave to a pond where you surface, as at Toriike.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training.

Toriike pin from Wikipedia; the boat sites have none. These are guided boat dives into caverns, halls and arches; the requirements come from the dive centres. Certification and configurations are estimates.
