According to CNET Japan, Japan’s three major mobile carriers, notably, Docomo, AU KDD, and YAHOO have agreed that Number Portability to be effective on October 24, while the details especially the fee asoociated with changing the carrier for the same number are yet to be known (CNET article in Japanese). I think given the competitive pressure and the nature of number portability, the fee would also be competitive.
