My Amazon JP order history only goes back to the middle of 2005 and I would estimate my first order there around Q3 2003 after I first came back from Japan, so I suspect that over the course of 2004/5 they went through a fair amount of database upheaval as that was when Amazon started to really explode there.
edit: looking back through my emails, they closed my account briefly for some security related reason when I changed from my university email address to the one I'm using now, so I suspect that my order history starts from when they reopened it. I didn't save any emails relating to it from my old Uni email account, so no further investigation is possible!
I'm surprised there was ever a time when you could use the same account, though, as far as I was aware Amazon JP was as close to a separate company as any of the Amazon branches could get.
edit2: wow, I haven't ordered anything from amazon.com (except for PSN credit) since 2011.
