    Yeah, also in East Asia, as like in Europe. According to the analysis by Y-chromosome DNA haplogroup, among Koreans, the most common is O2 lineage (about 40%), which is found with high frequency throughout East Asia, followed in order by O1b2 (about 30%), which is same as the left in the Korean Peninsula and the Japanese archipelago, and C2 (about 15%), which is same as the left in North Asia.

    Among Japanese, D1a2a lineage, O1b2, and O2 in the descending order, and these account for more than 80% of the all Japanese.

    D1a2a is a type that is unique to the Japanese archipelago, and about 30–40% of all Japanese belong to this lineage, which is the highest percentage. Especially high in Ainu people (about 85%) and in Okinawa, and it is said to has been present in the Japanese archipelago for over 35,000 years and to be a Y chromosome that is characteristic of the Jōmon people. On the other hand, it is rarely seen in the surrounding ethnic groups such as Han Chinese and Koreans. 

    O1b2 is found in about 30% among Japanese and Koreans. In the Korean peninsula and Manchurian, however, it is mostly O1b2a1a2, while it is O1b2a1a1 in the Japanese. There is a view that O1b2 group brought paddy agriculture to Northeast East Asia, and since in Japan it is not found in the Ainu people, it is assumed to be the gene of the rice farmers (Yayoi people) from the Yayoi period onwards. 

    O2 is confirmed in about 40% of Koreans, and is also the most common among Han Chinese (about 65%) and Manchurian (about 40%). In Japanese, 20%, which is lower than that of D1a2a or O1b2, and it is considered that there was a certain amount of influx of immigrants that arrived in Japan from the mainland China and the Korean Peninsula also after the Yayoi period.

    They are same people and there  is no such thing as Japanese its is just a nationality and they are 99.9 % Korean ethnic people .

    They came to the island from Korean peninsula and made of guryeo or guguryeo ,baekjea ,silla an maya ethnics, 

    Most Japanese citizens are of  Guryeo ethnic.. Japanese emperor and family are of  Baekja -kudara Koreans..

    The best way to explain this is  to watch this video in YouTube titled as :

    To some extent, yes. There have been people living in Japan from before 10,000 BC. They didn't just appear out of thin air. They moved there over time from East Asia and quite possibly what is now Polynesia. There were more Asians going to Japan to make up the Yayoi period as well about (-300 to 300). The further back in time you go, the fewer the people there were, and the closer their relations were.

    The Japanese don't want to acknowledge it, but the scientific fact is that Koreans, Chinese, Japanese, and many of the Pacific Islanders share not just one, but several common ancestors.  The scientific study of human migration based on human genetics has identified several groups of ancient migrations call haplogroups.  Here are some samples of maps showing the migration paths and the haplogroups:

    We ALL have common ancestors. Human live started in Africa and spread out from there. As people trekked eastward, there were no national boundaries, so yes, people spread across Asia, intermixing as they went. Physical features evolved based partly on the fact that there weren't many people to procreate with. Remember that it's people from Asia who crossed into what is now Alaska and spread throughout the Americas, which is why Native Americas share some physical features with east Asians.
