Japanese look like chinese, I'm sure they were chinese .How exactly and when was they seperated from China and formed their own country on an island ??. What was the reason they seperated?

There are subtle differences in features that most Western cultures could not pick out. To you they might not look any different but to the Japanese and Chinese they do.

Mitochondrial DNA shows us that the Japanese and the Chinese are two completely different races that have ended up in the same area:
http://www.utexas.edu/features/2007/ancestry/graphics/ancestry5_medium.jpg shows the Japanese settling around 50,000 years ago and the Chinese settling 35,000 years ago. They look similar because that what happens when you live in the same area - a person from Lithuania and a person from Scotland will both develop a New Yorker's accent if they moved there. Same goes for physiological adaptations to the region over many generations.

Fredsc-DO YOU KNOW WHAT YOUR TALKING ABOUT!!!!!!!!!!

no matter how you turn things round and round and round JAPANESE CAME FROM CHINESE ANCESTRY
Japanese changed and moved from a different island or what they call now japan as their country, almost 30 Families embark in a journey to follow what they think is right which ended to the formation of a new culture but ancient people of China and japan knew from themselves that they are ONE, KANJI the writing of Japanese numbers is the SAME as with CHINESE WRITINGS..dating back we all know that CHINA STARTED FIRST to be one of the Civilized Countries and Cultures, meaning what Japanese knows came from their root ancestry the CHINESE so as with the Taiwan, Singapore, Vietnam and other nearby countries INDEPENDENCE was only sought by these countries just to say that they are DIFFERENT

Haha, you guys are crazy. I myself am dutch, and i also see the difference between eastern Europeans (Polish, Ukraine ppl and stuff) and Dutch people (German people also dont look like Dutch people) but that doesn`t mean we`re from a different race. We share common ancestry way far back. Same counts for Japanese and Chinese people of course, they both are descendant from Mongoloid people (or just plainly they both descended from Mongols). Don`t you see how ridiculous it is to say that two completely different races of people would settle down in the same area and become very similar looking over time? Almost saying that if Africans and Arabs would both massively migrate into Europe (and Europe would be empty) that they both would become caucasians. lol

I think the often-stated: "Japanese look like Chinese" is nothing more than a myth. People acquainted with both countries or cultures would immediately notice that they are two different races. By Chinese, I mean Han Chinese here.

Probably the only "Chinese" groups that do have resemblance to the Japanese in terms of features, would probably be the Turkic-Mongolian- Manchurian groups who are recognized as Ethnic Minorities in People's Republic of China who are after all, members of the Ural-Altaic Language of which Japanese and Korean are thought to be likely members of anyway. Put it this way, one would readily notice the physical or facial-features similarity of a Uighur person with a Japanese person,than one would with a Chinese.

Yes- the Japanese did borrow a lot from China in terms of culture and one of the most visible and enduring aspect of this borrowing would have to be the Chinese Characters KANJI (HANZI as it is pronounced in Mandarin).BUT that doesn't make the Japanese racially Chinese. The modern Turkish and Malay-Indonesian languages are written in the Latin/ Roman script but that does not make these languages Indo-European.

Hhahaa You are damn right Gijs_v (The Japs who claimed that they think they are not decendants from the MainLand are Idiots!!, never learn about history) The first recorded Japanese Civilisation started when XUFU Arrived in Japan during the time of QIN dynasty, subsequently after that Chinese had been migrating to Korea and Japan to avoid conflicts in the MainLand China or those states who lost war during warring periods. The peak comes during the Tang Dynasty. They brought along their local cultures to Japan.

The reason why Japanese looks like chinese because of Xu Fu:
