I don't think they were from the same tribes. Before nation states began to solidify in Korea, there must have been hundreds of tribes living on the peninsula. It's impossible to know if they were all the same people or not but it's certainly incorrect to say that the tribes who stayed behind in Korea were the same as the tribes who migrated to Japan.These tribes may have been totally different from each other for all we know.
Still, you can't discount the fact that a good deal of the immigrants WERE in fact, from the Korean peninsula. Where did you find that info about Chinese immigrants ? Does it matter ? I think every East Asian ( Mongols included ) must be part Han Chinese.
Still doesn't get rid of the fact the migrating tribes were from the Korean peninsula (and China). People call them "Korean tribes" because they lived in Korea, and if they lived in Korea, there is a good chance that they were the ancestors of the modern day Korean people.So while it may be incorrect to say that Japanese = Korean, it is true that Koreans and Japanese are very close genetically. The present day PRC does not, in my opinion, represent only Han Chinese. People call it "China," but it fact it is quite different from the earlier Chinese dynasties, where the only true citizens were the Han (Manchus and Mongols don't count because they only functioned as the upper classes). "Chinese people" in the modern sense can mean almost anything.
No one ever denied migrations from Korea peninsula,but only disputed hyper-inflated suggestion of Japanese are basically Koreans or predominate Korean ancestry because it's hogwash.
It's recorded in Japan's Shoban 諸蕃 ( or 蕃 別 banbetsu ),a family registry designated Japanese clans known to be of continental descent.

Although there is no doubt on genetic closeness of Japanese and Korean,but its relatedness is ' relative '.I am sure Japanese of ' definite ' Korean ancestry should be closest to modern Koreans,but most other Japanese aren't.in the case of multi-ethnic PRC,specific provinces & region ( combined area larger than Japan or Korea peninsula ) have populations genetically close to Japanese & Koreans.On the other hand,Koreans have no genetic relation to Jomon ancestry which is near 50% of Japanese gene pool.
Japanese typically consider themselves 50% 縄文人 ( Jomon ) & 50% 弥生人 ( Yayoi ) not Siberian Korean Chinese Mongol.
Jomon contribution to modern Japanese @ 40.3%, with the highest frequency in the Ainu (75%) and Ryukyuans (60%). On the other hand, Yayoi Y chromosomes account for 51.9% of Japanese paternal lineages, with the highest contribution in Kyushu (62.3%) and lower contributions in Okinawa (37.8%) and northern Honshu (46.2%). Interestingly there is no evidence of Yayoi lineages in the Ainu.More recently,Yayoi Y chromosomes that originated in Southeast Asia expanded to Korea and Japan with the spread of wet rice agriculture.
Koreans do not have Y chromosome D2.The D2 system is Ainu 88%, the Okinawa people 56%, mainland Japan 50～56% and Korea 0%.
1 academic research on ' dual origins ' of the Japanese.
A set of 81 Y chromosome single nucleotide polymorphisms (SNPs) was used to trace the origins of Paleolithic and Neolithic components of the Japanese paternal gene pool, and to determine the relative contribution of Jomon and Yayoi Y chromosome lineages to modern Japanese. Our global sample consisted of >2,500 males from 39 Asian populations, including six populations sampled from across the Japanese archipelago. Japanese populations were characterized by the presence of two major (D and O) and two minor (C and N) clades of Y chromosomes, each with several sub-lineages. Haplogroup D chromosomes were present at 34.7% and were distributed in a U-shaped pattern with the highest frequency in the northern Ainu and southern Ryukyuans. In contrast, haplogroup O lineages (51.8%) were distributed in an inverted U-shaped pattern with a maximum frequency on Kyushu. Coalescent analyses of Y chromosome short tandem repeat diversity indicated that haplogroups D and C began their expansions in Japan ~20,000 and ~12,000 years ago, respectively, while haplogroup O-47z began its expansion only ~4,000 years ago. We infer that these patterns result from separate and distinct genetic contributions from both the Jomon and the Yayoi cultures to modern Japanese, with varying levels of admixture between these two populations across the archipelago.The results also support the hypothesis of a Central Asian origin of Jomonese ancestors, and a Southeast Asian origin of the ancestors of the Yayoi,contra previous models based on morphological and genetic evidence.http://www.springerl...1g0300430k6215/
it's fallacy to regard Japanese and Korean nationalities are closer genetically than all other NE Asian groups.
It's like saying British ( English Scots Welsh Irish ) are more closer related to some specific continental European nationalities ( they too are mixed with other European tribes and people of non-European race ) than with multi-racial & multi-ethnic America ( by discounting 50 million+ British ancestry ) because the population has non Anglo-Saxon ( or Nordic ) genetic component of 45 million Italians,a few million Greeks,many million White-Hispanics,some racially intermixed Whites,Asian-Americans,' Asiatic ' native Americans,Black-American,etc ..... therefore ' pull ' North America away from Europe.
Frankly,it's a pathetic argument.
Let's me repeat,it's a bias has aspects that reflect cultural/social/historical currents of the moment ( This debate wouldn’t be worth mentioning if it's true or Koreans and non-NE Asian surrogates wouldn't harp on it in cyberspace ).It's a fad of late will fade in due time.
