> I'm not sure why you cite Japan as an outlier regarding size preferences and smaller-than-average hand sizes, which I generally do not believe to be true and could not find any hard data to cite (source: I live there).

Human hand size is proportional to height across races, and average height in Japan for male and female is several centimeters shorter than in other markets like the US and Europe. So it would be surprising if the average Japanese hand size was not smaller than the average hand size in US or Europe.

Of course, I have no idea whether that difference would be enough to affect smartphone size preferences.
