I would guess that the high number of No Preference votes is a consequence of it being a non-North American Worldcon. Some of the Japanese eligible voters may have felt that they *should* vote, but had no real preference between the bids, since they would be attending neither, whatever the result. Even more will have just not voted, of course.
For once, No Preference may just mean that?
