Szinger) / 2:33 am Jun 10, 1991 / *We will be having a visitor from Japan in out lab this summer, *and he is wondering if his 100V Japanese electrical equipment *will work on North American 120V/60Hz electricity. What's the *line frequency in Japan? Can his equipment tolerate this much *deviation from nominal without undue risk to life, limb, and *property? If not, is there an easy way to get it to work. I think they use 50 Hz in Japan. The voltage difference is more likely to cause problems than the frequency difference. I wouldn't try to use anything with with electronics in it, the filter capacitors are likely to explode. You need to get a step down transformer to convert down to 100 V.
