hello , About Nakamoto did not disclose any personal information when discussing technical matters. They provided some commentary on banking and fractional reserve lending. On his P2P Foundation profile as of 2012, Nakamoto claimed to be a 37-year-old male who lived in Japan, but some speculated he was unlikely to be Japanese due to his use of perfect English and his bitcoin software not being documented or labelled in Japanese.

What does "unlikely to be Japanese due to his use of perfect English" mean?!!
I know of a Japanese woman who is around 40 years old, and she speaks more than perfect English. Do they even know the meaning of the word "bilingual"?
Besides, if someone wanted to make an international product/website/invention/whatever, what language would be appropriate for people all around the world to understand that thing? Of course, English. It's number 1, an international language that everyone is trying to learn, and it's much, much easier to be learnt.
I am not saying that he is Japanese, but rejecting the thought based on those speculations is simply absurd.
