It doesn't mater whether Satoshi Nakamoto is a male, female, or a hermaphrodite. Honestly, we don't even know whether this "Satoshi Nakamoto" is a single person, or a group of individuals.
From the name itself, Satoshi Nakamoto, I bet he is a male and he is a Japanese.
Most likely, "Satoshi Nakamoto" is the
nom de plume /
nom de guerre of a single individual or a group of individuals. He/She can be of any nationality, and right now we don't have enough information available with us to reach a conclusion.
Actually there is more evidence we gathered that point us to the conclusion that he is NOT Japanese at all.
Most notably: his use of perfect English language and including in his posts phrases like 'bloody hard' indicating he is more of a British English speaker.
Also his original bitcoin's white paper is written exclusively in English, with no hint of Japanese - which is uncommon for a Japanese person.
