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.....
