Нашел про Йонагуни и все стало ясно:

Several analyses indicated that a certain structure, which measured 120 m in length, 40 m wide and 20–25 m high, was 8000 years old.[citation needed] Several noted writers, including John Anthony West and geologist Robert Schoch argue that under inspection, the "ruins" turn out to be largely explicable by ocean erosion and coral reef settlements. Professor Kimura still maintains that the structure is human made.

Most geologists familiar with the area also maintain that the structures are mere geologic processes of natural origin and consistent with other known geological formations.[2] They point to the fact that local rocks above the surface have right angle cleavages, and that aquatic flora and fauna have simply smoothed out much of the surface of the rocks. Photographs show with a varying degree of clarity parts of the formation with precise geometrical shapes, in varying complexity. Although this may be taken as a strong hint of human presence, many natural formations, such as the Giant's Causeway, or natural staircase structures on Old Rag Mountain[3], present similar shapes.

At the time that Kimura first suggested it might have been constructed, the affected area of Yonaguni composed a land bridge between the islands of Taiwan, Ryūkyū, and Japan with Asia in the days of the ice age. The level of the sea was lower than at present because of the ice accumulated in the temperate zones. Geologist Teruaki Oshii suggests they have been constructed before the end of the glacial era.

Kimura now argues that Yonaguni is the site of a city at least 5,000 years old which sunk 2,000 years ago, while Robert Schoch says "they're all natural...It's basic geology and classic stratigraphy for sandstones, which tend to break along planes and give you these very straight edges, particularly in an area with lots of faults and tectonic activity."[4] Kimura claims to have identified at least 15 structures off Yonaguni and Okinawa including a castle, linked by roads and water channels. Kimura obtains his 5,000 years old date for the city from the dates of stalactites in adjacent underwater caves. Kimura also says that he has found images of animals and people, while Schoch considers them natural scratches on the rocks.

Some also speculate that several of the seemingly natural features could in fact be human made, such as the discovery of what some called a "face" on the side of one of the monuments. To date, there is no archaeological evidence to support this theory.

Идет нормальная научная дискуссия. Никакого замалчивания нет. Пока что большая часть научного сообщества склоняется к мнению, что это естественное деформирование рельефа и деятельность человека тут не при чем. Вот и все
