N-M128 (xY23738,CTS1350) formed 1900 BC is now living in Fukui, Japan. His cousins who separated in 1900 BC live in Vietnam and China.

Two samples of N-Y23749 are survivors of a bottleneck that started 4600 BC and ended 1950 years ago. Their cousins that separated from them 4600 BC today live in Hebei on the Yellow Sea.


Note that these branches are formed by just one and two individuals on YFull at this time. As more data accumulates it will be interesting to consider whether either of these branches may represent Jomon hunter-gatherers or Yayoi who introduced agriculture and bronze and iron weapons and tools 1000-800 BC from the mainland.
