Step down voltage for Japan to US turntable

Having purchased a turntable labeled 100v 50/60hz I'm wondering if it is necessary to use a step-down transformer to convert US 120v to 100v. I've heard both that you do and that you don't need to do this. Can someone tell me if they have experience in this application? Thanks.

Transformers don't limit the voltage, they only change it by a fixed ratio. If you buy a 120-100 then that ratio is 6-5. If you feed it 125 it will output 104.2V

Since the voltage in Japan varies as much or more than it does here I think that is acceptable.
