じゃあ、おやすみー。俺は英語のレッスンやったから寝るわ。超眠い。

Where and when did we come from? This is one of the most interesting questions not only for me, but also for the entire Japanese people. Almost everyone understands that people who invented the wet-rice farming were not our ancestors.
Many scientists now think that it came from the Korean peninsula, and the study by the University of Tokyo strongly suggests that Japanese and Korean people have the same ancestors.
This is very convincible as both ethnicities look very similar. I hope that many Japanese people accept this "reality" to understand both ourselves and this world. Thank you for reading. Good night.
