Around 40,000 to 35,000 years ago, primordial Japanese had separated from primordial Tibetan and around 50,000 years ago primordial Tibetan had separated from primordial Andamanese. And Andamanese had arrived in Asia around 70,000 to 60,000 years ago. Recent DAN studies have discovered that the Andamanese, Tibetan, and Japanese have shared the same haplogroup D, of which among the Andamanese is 100%, Tibetan is 41.3%, and Japanese is 34.7. Also, linguistically Tibetan, Japanese, and Andamanese have kept the same basic structure. For instance, their word order is SVS. Particularly, both Tibetan and Japanese languages need special instrumental cases to indicate actors. For example: Watashi WA gohon O tabemasu. Tibetan people say: ང ས་ ཟ་མ་ ཟ། I food eat Wata nabe GA Tanaga NI hanasu བཀྲ་ཤིས་ ཀྱིས་ ཚེ་རིང་ ལ་ སྐད་ཆ་བཤད། Watanabe/Tashi Tanaga/Tsering to speaks The word order in both Tibetan and Japanese is SOV and the most astonishing characteristic is the subject indicator "WA" and "GA" in Japanese and "ས་" and "ཀྱིས་" in Tibetan. None of the other languages have this grammatical feature. More example: Higashi E ikimasu ཤར་ཕྱོགས་ ལ་ འགྲོ East to go Please pay attention to the direction indicator "E" in Japanese and ལ་ in Tibetan. Let's take a look at the morphology in Tibetan and Japanese: shiro I དཀར་ བོ། white kuro I ནག་ པོ། black Please see the suffix "I" in Japanese and "བོ་" or "པོ" in Tibetan
@@purimadonnanamamoritamae Thank you so much for your comments. You have mentioned that the root of Japanese language is connected to Mesopotamia. I think you are right because Tibetan language is closely related to Sumerian language and there is a book written by Polish linguist Jan Braun which is entitled "Sumerian and Tibeto_Burman". It would be interesting if you check out this book. Interestingly, Sumerians called themselves as "black head" and Tibetans are also calling themselves "black head". Maybe it is purely coincident but still worth to meditate on it since linguistically there is a close relationship between Sumerian and Tibetan. Plus, a genetic element of Sumerian people has found no other than people live in Himalayan region. All the best.
