(p02) Prologue 1
Early history
From now on, the last glacier time finished about 10,000 years ago.
The large flood occurred in every corner of the earth for the rapid
temperature rise.
It made the civilization which existed in the plain part destroy
completely.
There was what is called " the Aska civilization" into
the civilization ruined at this time.
The race in which this ancient civilization was formed was the Mongoloid
who makes the north Siberia continent the origin.
The race was called Askan.
A mongoloid is divided roughly into two lines.
The Askan belonged to the lineage currently called original Mongoloid
of them.
They were the same lineage as many races which are present in the
Siberia northern part of today.
As the feature, engraving of a face is comparatively deep and it
is hairy.
Their blood type had many O types, and had the thickset form.
In BC20,000 period, some of Askans moved later on the huge beast
which goes south in connection with chill-izing of climate, and
he arrived at the China continent.
In the beginning which advanced into the China continent part, Askans
had the culture of the late Paleolithic period represented by pointed
tool culture.
When BC19,000 period came, they resulted in gravel machine culture
and entered the Nakaishi machine era.
If these days come, they would acquire nomadic technology by contact
to the race of Nishikata, and eating habits will also have been
stabilized.
Those days, the sea surface benefited lower about 120m than present
the layer of the huge ice which existed in the polar zone.
Therefore, more than the half of the continental shelf of the East
China Sea and the Yellow Sea was land.
When BC18,000 period came, the tribe who was present in the area
along the shore of the east of them emigrated to the Ryukyu islands
on the opposite shore.
The tribe was called Mui tribe.
Four of Amami Oshima, Okinawa, Miyako, and Ishigaki islands were
big islands.
Those islands had one 10 times the area of present.
Furthermore, the great island existed also between Okinawa island
and the Miyako island.
The total area of the Okinawa district is about 3200 square kilometers
now including the Amami islands.
Those days, these had the area of 18,000 square kilometers in sum
total.
The Askans who were leading the primitive hunting collection and
the nomadism life civilization-ized quickly.
The greatest factor was based on they having discovered the rice
and having established the growing method.
Of course, the East China Sea continental shelf has sunk now.
But, those days, there was a marshland in the place to reach there.
The rice of japonica seed grew wild there.
Discovery of a rice brought Askans rapid increase of population,
and formation of a village.
The land of the "East China Sea continent" (we name the
past continent so temporarily) was also vast, and it also had large
population.
However, argument arose among same families over the water supply.
They received invasion of a north direction different race or a
mountains tribe.
The damage by the savage beasts which lived those days, such as
tigers and wolf, etc. was generated frequently.
These demerits deprived them of room to build civilization.
The Mui tribe abandoned settlement under the situation of either
of the above.
They emigrated to the Ryukyu islands on the opposite shore.
In BC16,000 period, the Mui tribe who emigrated to the Ryukyu islands
invented the letter in the place.
They established the oldest civilization "the Mui civilization"
in the world preceded with the Aska civilization.
The Mui tribe can have the latest civilization in the world.
The reason is because the Ryukyu islands were blessed with geographical
conditions.
The East China Sea continent coast district in Pleistocene era had
normal temperature lower than present about 4 degrees C.
The humidity was also relatively low.
The climate of the Ryukyu islands was warm through every year because
of oceanic climate.
However, they might be afflicted by the attack of a typhoon.
Lapsing into a water shortage had little them by the favor.
A certain tribe emigrated to the Japanese Islands via Korean Peninsula.
It was the period about with the Mui tribe having emigrated to Okinawa.
The tribe was called Suizim tribe.
In this that time, the southernmost end part of Korean Peninsula
and the East China Sea continent were an adjoining land.
There was large Tsushima between Korean Peninsula and the Japanese
Islands also several times rather than present.
The west strait and the east strait existed there.
The width of a west strait was about 10km.
The width of the east strait was a narrow strait only with several
kilometers.
Iki island was a part of Honshu.
The Japanese Islands of those days had chill climate in the mountains
zone of a northern part or the central part.
The southern coast district was comparatively warm climate.
The geographical feature of the Japanese circumference of those
days differed from present considerably.
Sakhalin was an adjoining land in the Maritime Province.
Sakhalin to Hokkaido and Kunashiri island were continental portions.
The Tsugaru strait froze over in winter.
It was separated and even Honshu island, Sado island, Shikoku island,
Kyushu island, Yaku island, and Tanegashima island existed as a
huge island which stood in a row in the shape of a saber.
The island was called Suizim island.
The Suizim tribe who went over Suizim island continued movement
in quest of the optimum ground of a rice crop.
The Melanesia descent sea race and the Negrito tribe resided permanently
in the south area along the shore of Suizim island before tthe Suizim
tribe invades.
They were performing fishing and primitive farming, such as a taro-potato
and yamu-potato cultivation.
Start of the Suizim tribe's invasion drove away natives to mountain
area.
The Suizim tribes were superior also in culture and military.
Those days, the offing of the present Yaku island of Suizim island
was the southernmost tip.
The tribe who goes over the tokara islands which separated 20 morekm
from there also appeared.
There was 40km from the southernmost end of tokara islands up to
Amami islands.
There was a reef which can anchor on the middle point.
The island continued from Amami islands continuously up to the Ryukyu
islands.
On Ryukyu islands, a former occupant's Negrito descent tribe was
leading primitive fishing and the collection life.
The savage beast other than a habu-snake did not inhabit the islands.
The Mui tribe who emigrated there produced the room of a life, shortly
after the rice crop spread.
The land situated in the offing of the Miyako island northeast which
has sunk especially now had flat all of the island.
Since submersion was experienced there to the past interglacial
epoch, the habu-snake did not live.
Therefore, they greatly prospered.
The island was called Nirai island.
The area was about 3000 square kilometers.
