Wow, it really states that. Why would wikipedia go overboard to cover up a city underwater? Oh, I know why...

That's really demented. If someone believes this is natural, they probably also think that 2+2=5.

I like this statement from wiki "Marine geologist Masaaki Kimura claims that the formations are man-made stepped monoliths.[1] These claims have been described as pseudoarchaeological." - https://en.wikipedia.org/wiki/Yonaguni_Monument . The way the media states "Look the other way".

Nice find. I suppose it is another example of a flooded city like the chinese did with theirs long ago and even recently that the government would keep secret. This deserves to be researched in depth. But it is definitely not natural... What a clown world... :D
