In reality,
1 Peninsular Japonic is nothing but a WAJIN which korean themselves hate so much until now and it is nothing but a Japanese .
The terms Yayoi and Wajin can be used interchangeably, though "Wajin" (倭人) refers to the people of Wa and "Wajin" (和人) is another name for the modern Yamato people.[9]
Japonic language speaking people called Yayoi came to the peninsula in 1500 BC from sangdong china , and the Koreanic speaking Tungus people came to the peninsula a lot later in 300 BC from Manchuria
It is a 1200 year gap.
It is impossible that this is the same people.
Yayoi means nothing but an ancient Japonic race.
Its an ancient East Asian people who were speaking Japonic language with no Japanese or Korean identity of now were formed yet.
Most linguists today see the Japonic languages as their own distinct language family, not related to Koreanic, but acknowledge an influence from other language families (and vice versa). Vovin (2015) shows evidence that the early koreans borrowed words for rice cultivation from the Peninsular Japonic language According to him, the Middle Korean word ps^r (rice) is loaned from the Peninsular Japonic *wasar
2 In official ancient records of both japan and Korea , connection between japanese imperial family and Korean is only one princesses from Beakje was
Married with Japanese emperor as fuck toy
Except it there is no any connection officially
3 Beakje imperial family was destroyed by Silla which is direct ancientor of modern South Korean (Korean language is based on silla)
And bekje imperial family was officially escaped from Korea to japan and being under the clan of japanese imperial family
https://en.m.wikipedia.org/wiki/Kudara_no_Konikishi_clanBut In the Korean logic
1,One princess from Beakje was concubine of japanese emperor.
2, So japanese emperor has blood of one Of the princess of Beakje
3,So emperor of japan was Korean! And japan is colony of Korea!
Surprisingly many Korean believe this shit.
