When did Japan first exist?

Japan existed as early as the Yanhuang period.

1, there are no protozoa on the island of Japan.

The Japanese island, which has been exposed to the sea for a long time since the appearance of Chinese mainland, does not have the conditions for human formation.

Only monkeys, foxes (it is highly suspected that foxes were "smuggled" here by the mainland) and individual birds and animals were produced.

2. The origin of the calendar.

It can be clearly seen from the title of the perpetual calendar "Huangdi Calendar" that Huangdi Calendar is the calendar of the earth's time course created by Huangdi according to the latitude and longitude celestial positioning system, and it is the earliest calendar used by human beings on the Loess Plateau.

Calendar, hence its name, is a basic time concept to calculate the daily variation of the earth with the sun ball as the reference.

However, to determine the prime meridian position of the zero line of longitude and latitude, it is necessary to cross the sea to the main island of Japan.

The earliest people who set foot on the island of Japan came from the Loess Plateau.

As early as the end of the primitive matriarchal clan era (about 300,000 years ago), with the efforts of Yan, Huang and others, after inventing food technology and human blood test technology, and completing the transformation from the primordial matriarchal clan lineage reproductive form to the consanguineous reproductive form, we investigated the earth environment, invented and set up a latitude and longitude celestial positioning system, and set up a meridian zero line observation station on Fusang Island (Japan Island). The staff of the Observatory first observed the sun rising from the meridian (the name of the sun ball in front of the sun), set the sunrise position as the prime meridian of the meridian zero line, and named Fusang Island "Japan Island", which means "sunrise begins". The staff of the observatory who stayed behind were permanently left on the island of Japan after the social changes in the mainland, becoming the first batch of permanent immigrants on the island of Japan.

Therefore, Japan existed as early as the Yellow Emperor when people from the Loess Plateau came to the island.

The second batch of mainland immigrants, led by Xu Fu, a warlock of the Qin Dynasty, colonized the Loess Plateau in large numbers.

The third batch of mainland immigrants were mainland laborers who were forced to come to the island during the Sino-Japanese War and World War II.

The fourth batch of mainland immigrants are the families of corrupt officials who fled to Japan after the mainland opened up.
