It might be marginal because Japanese P5 are designed to work at lower voltages - though their upper limit includes most of the US unless yours has a high enough margin. There’s a very good chance it would be fine, and if the voltages were compatible, then you’re ok.
Paul, thanks for the reply. Turns out that a PS5 in Japan is only about $3200, which is not that much markup. You chose a good distributor over here! I’ve seen some truly horrendous profit-grabbing markups.
