Don't know where you read that satoshi is from Japan?even if he has a Japanese's origin , he could be living in the USA right now.
No, not me but people think he's from Japan because of the name Satoshi Nakamoto. He could anywhere, he could be using VPN. But I put him in the USA.Developers/coders are typically stereotyped of having inconsistent sleeping patterns, especially when it comes to big projects. Even though I appreciate the effort you've put into the post, and the images it's nothing more than speculation.
You got me... I assumed he wasn't a stereotype developer but a normal human... after all I just speculated.With sleeping late and getting up early, you'll have to move the time approximately 3 hours.
Well USA is GMT -5 to GMT -9... I will move Satoshi around, but will keep him in in USA
