Around 1 century BC, there were more than 100 small countries in Japan (some of which established diplomatic relations with the Eastern Han Dynasty), and later these small countries gradually unified. In the 4th century BC, relatively large countries were established in Kansai. It is said that the ancestors of today's royal family finally unified these countries. At that time, Japan included western Honshu, northern Kyushu and Shikoku. Therefore, it will take a long time for this country to be unified. Therefore, it is difficult to make an accurate judgment on the exact date of the birth of Japan.

According to ancient stories and Japanese records, the first emperor Emperor Jimmu was established in 660 BC and acceded to the throne. The date of his accession to the throne is equivalent to 1 1 in the current Gregorian calendar, so this day is designated as the "founding day".
