Depends on the game and how you buy it. In general, buying digital is easier and cheaper in the US, due to more PC releases and aggressive price cuts and sales. Japanese digital stores have much less frequent and less generous sales, and older games don't get their base prices reduced by much. But if you buy physical copies, then the Japanese market might be cheaper simply due to the greater supply of older games, and potentially the currency conversion of newer games.
