Can I use a Japanese appliance in the US?

I�fm looking to purchase a transformer for a product I purchased from Japan, because I live in the U.S. The product is a baby sanitizer device and its 220V/60Hz, 90W (UV Lamp 6W)Can you tell me what kind of transformer I would need to purchase, so that the product would work in a U.S. outlet safely?

Are you sure it is 220V? I thought Japanese goods were 100V which work OK in the U.S.

Japanese electric products are 100-110v.

It should be ok in the US (assuming its 100v), although you may want to get a 120v to 100v stepdown converter anyway as ones rated for your needs are relatively cheap and easy to find online.

The product Specifications state the product is:
AC 220V-240V with 2 round pins plug for C type

C type is not for Japanese usage.
Plugs in Japan is A type, same to that of US. C type is for Europe, probably.
I am afraid that you might have bought a wrong one in stores for foreign tourists.

Yes, you are correct. I just found out the product came from South Korea, but it was shipped from Japan. Now I'm really confused. Thanks for all your help.

In that case you definitely need a stepup converter. They're not too expensive. Something like this:
