Came across this and thought that it might find it interesting

There's a nice Nat Geog article about it here (Japan's Ancient Underwater "Pyramid" Mystifies Scholars)

I remember hearing about this a while ago (maybe in Fortean Times?) and it does sound fascinating. I'd love to visit.

Yonaguni is a nice dive site - but when you see the site as a whole it is, for me, fairly clear that this a natural geological formation. In the same way that the granite hexagonal (?) columns of the Giant's Causeway look too regular to be natural, the shear planes here give a similar impression.

There's all manner of great diving in Japan - most untouched by foreigners

Yonaguni.....

Yeah...... it's a famous destination here. I haven't been there yet myself - it's not a cheap trip!

There's a lot of debate as to whether the formations are natural, or man-made.

The site is usually very high current which makes it a fast drift dive. I have a mate who went there and the dive plan was to get down to the bottom as quick as poss and shelter behind a wall - then when everyone's ready just move into the current and drift.

February is a good time to do it. It's cold, but at the end of the drift as you get blown out into blue water there are hundreds of schooling hammerhead sharks. I believe it's a mating location for them.

I'll get there one day.....
