Most Accuphase products have multi tap primaries, at least the few I've had come through here, so any qualified tech should easily be able to convert it for 120V operation by reconfiguring a few jumpers. It may however be that products sold in Japan have only a 100V primary transformer installed.
I would not recommend running a 100V product on 120V, you could however buy a step-down transformer for few hundred $ that will facilitate proper operation.
Best of luck
