Converting a Japanese Word doc to Mobi help, please

Hi! I am having some issues with this. I have a word document of a Japanese book. Concerting to Mobi itself is not the problem. The issue is with the orientation. The book is in vertical format with the first page beginning at the back of the book (as opposed to the front as in English books) and the pages are then flipped from left to right (or the left clicker). I need the book to be reversed in the mobi format. And then set to start at the end.

I know this is possible as other Japanese books do this. For example:

http://www.amazon.com/temaneki-taoru...ese+Edition%29

I would love some help wit this, feeling a bit stuck at the moment.
