The original Japanese inhabitants are called "Jomon" ~ they are also mostly the same race as the Ainu, but their cultural relationship is quite distant. A third group that shares in the same ancestry as the Jomon and the Ainu are the more modern occupants of Japan identified as the Emeshi.
Japan, contrary to claims of the ruling elite is a multi-racial, multi-ethnic nation made up of the original inhabitants ~ the Jomon, their presumed descendants - the Emeshi, the Ya-yoi ~ immigrants from Central and Southern China who introduced rice culture to Japan about 500 BC give or take a few years, a Korean substrate that includes Korean technicians and artisans brought to the islands by the ruling elite from about 800 AD right through the 1800s, and a later Korean group consisting of Koreans brought to the home islands during the occupation of Korea from the early 1900s to 1945, and finally THE RULING ELITE, and they go by the name ROYAL FAMILY and DAIMYO.
The RULING ELITE are ethnically distinct from all the other Japanese since their origins are undoubtedly among the Sakha/Yakuts. These people conquered Korea and Japan in the mid 500s, and imposed their language (which is an Eastern Turcic dialect) and religion (Buddhism) on all the others! They are also pretty much identical to the Chinese, and for thousands of years were technologically their equal ~ they just lived further North in Siberia running vast herds of every known domesticated animal, AND further South in India. They controlled Trade Routes to the West of the Chinese core.
Technically speaking the RULING ELITE were overthrown in the late 1800s in the Meiji Restoration. In reality they're still there.
BTW, the Samurai were formed up from Emeshi and Daimyo families and end up as a mixed-race military class.
OK, so how do you tell these groups apart?
Actually, all you need are some dental X-Rays. The Jomon, Emeshi, and Ainu are going to have a high incidence of having molars with 5 roots. 40% of the modern Japanese population has such teeth. Their cousins in China also have the same teeth, so if it wasn't the beards, foreheads, eyebrows or modest differences in standard skeletal lengths, you could figure them out by checking their teeth.
This "other race" is one of two off-shoots from the original Cro-Magnon branch that went East from their homeland in South Central Asia about 35,000 years ago. In effect, the Eastern branch split into the Chinese and the Jomon/Emeshi.
The Western branch went to Europe and became the Europeans!
Up until the big split between the Chinese and Jomon/Emeshi everybody had beards!
The RULING ELITE in Japan also have a high incidence of Jomon tooth forms because, as always, the RULING ELITE gets all the good lookin' chicks. It gets harder and harder every year to differentiate between the different groups. People do stuff ~ as usual.
The Sakha/Yakuts also have a high incidence of the Sa'ami specific X-factor DNA sequence ~ plus they herd reindeer.
Of interest, the RULING ELITE also seem to have the same set of Chromosome 6 variations found among the Sa'ami. They still look doggoned Japanese though (their faces form the very basis of traditional human representation in Japanese art). Their ladies have all the larger breast sizes in Japan and import bras from the West ! The connection there seems to have been the sojourns in India.
What that means is simple ~ if you seek out a Caucasion connection to the Japanese, you're digging a dry hole if you depend on just the Ainu. What you need to do is check out the Royal family.
Get Akahito to give you a DNA sample and go to it.
Re cent DNA tests indicate that they were bunch of drunk Ukrainians who could not find their way back, deeeevelopiiiing....
Oppenheimer says his DNA studies indicate that 50% of the Europeans can trace their origins to a guy in northern Pakistan about 45,000 years ago who made their way to Europe through Russia.
He says the other 50% (of Europeans) can trace their origins to an off-spring (a thousand years later) of the original guy and they made their way to Europe through the Middle-East.

Thanks for the information muawiyah. This may seem a little off the wall, but do you have any explanation why supposedly pure-blood Japanese have curly hair?
Make that “pure-blood” Japanese from an upperclass family, descendants of Samurai?
Thank you muawiyah. As usual in FReepland, people know some serious stuff. Well said.
