I'm wondering if perhaps this island might be the now recognized Yonaguni, a Japanese island about a hundred kilometers east of Taiwan.

Yonaguni Monument: Is this part of a human-influenced structure at Yonaguni? These 'monuments' (as they have been called) may be natural formations that have been shaped by human hands. Is Yonaguni a relic of Kasskara?

The destiny of the inhabitants of Atlantis
According to White Bear, not all the inhabitants of Atlantis perished when their continent was destroyed. Those who had not taken part in their queen's attack on Kasskara were saved. They also wanted to come to the new continent, but the Creator had promised that the new land would belong solely to the Hopis' ancestors for a long time. "Although there was no Hopi yet on this new continent, the inhabitants of Atlantis could not come to South America. The Creator did not want to have them there," White Bear said, "So he sent the Kachinas to prevent them from moving towards the West because, even if the survivors had not followed their chiefs, they remained inhabitants of Atlantis nevertheless."
White Bear said that in ancient times when the Third World was created, the people of Atlantis also associated with Kachinas, but the Kachinas left them when the Atlanteans became malicious. "The Kachinas directed them east towards areas that today are called Europe and Africa. But their capacities had been removed from them. Nailed to the soil, they could not fly anymore and could only survive if they left in small groups and each group carried only one small portion of the total knowledge which they had before," White Bear said, which explains the importance of clans to the Hopi. "This is why the people over there (Pacific region) do not have a memory of their history which is comparable to ours," he said, adding that when Atlantis destroyed the Third World, the Creator reduced it to a low cultural level. "But after their punishment, which lasted hundreds of years, they started to develop again. Think of the culture of the Egyptians. For us Hopis, this time is not so remote, and all of this forms part of the Hopi tradition."
Toowakachi: the Fourth World
With this Fourth World, Toowakachi, which means "beautiful country for all men", we are in the middle of earth and humanity's lifespan, White Bear explained. "We are in the fourth of a total of seven worlds which we must cross. Three are behind us, and three are in front of us. This fact is expressed in our impenetrable rituals as well as in some remains which were found in Mexico and in South America," he said. "Time wise we already exceeded half of the seven worlds' lifetime because the duration of each world to come is shorter." White Bear described Taotooma, a city about the size of Los Angeles, saying that a section of that ancient city was what we today recognize as Tiahuanaco (Tiwanaku):
We call the part of the Fourth World which first emerged out of the water Taotooma. In your language this name means "the place that was touched by the arm of the sun". We Hopis say that it is the first part seen by the eagles, which were sent by the Kachinas. The eagles fly very high, and they saw the new country emerging from water. This is why we admire the eagles. Thus, we were in the new country, and finally the last group arrived by boat. With their arrival, the migration was complete.
When we stood on the
coast of this continent, we looked behind us and saw the islands that had sunk.
The Kachinas had given us a "third eye" (perception, wisdom, insight), which allowed us to see
the disappearance of our motherland and the islands," White Bear said.
Both symbols of the Mother-Earth of the Hopis
Not all of those who came to the Fourth World and who lived in Taotooma were the Hopis' ancestors. "We should rather say that our ancestors were among these people. Our ancestors are those who arrived at Oraibi and settled there definitively; those are called Hopis," White Bear said, adding a clue about the time scales involved:
"A rather long time passed between the arrival of the first group on the flying shields and the arrival of the last group in boats. It is said that it took 3000 years before we all came together. All this happened a long time ago because the arrival of those which were on the flying shields took place 80.000 years ago. We have a very simple way to speak about the long periods of time: Soomody means 1.000 years. Soo means "star", and you know how many stars there are! So the migration started 80 Soomody ago."
While such a vast time scale requires us to reassess some of our assumptions, consider that in 2008 a stone bracelet was unearthed in a Siberian cave that is likely to be 40 thousand years old. According to the Archaeological Institute of America, "oxygen isotopic analysis" indicated that the bracelet found in Denisovan Cave was "In the same layer [that they] found a Denisovan bone." Anatoly Derevyanko, director of the Russian Academy of Sciences' Institute of Archaeology and Ethnography said he believes the layer in which the bracelet was found had not been contaminated by later human activity.
White Bear said those who arrived in Taotooma could settle only in a small area where everyone was to live together. "That shows why my people are certain we were the first and only people on this continent. There are tribes in America which came much later because the ice had melted in the north, which I will tell you more about later."
"A long time before all this occurred, the Creator had shown us planets. He made this formidable offer to us after having been created as living creatures. But we failed because we did not follow the instructions he had given us; we did not respect his law," White Bear said. "This is why we had initially this small portion of land--in order to learn how to dominate our feelings and live together."
