camera? most of the camera chargers right now are from 100-240V so I don't think you will have any problem with that.

I bough a sony camera before and the charger is from 100-240V so I did not have any problem using it at home.

power converters , hmm i don't think so.. there are affordable ones.

if you are planning to get home appliances in Japan then you will probably need power converter but if electronic gadget, i think you wont need..just be sure to check the power support ..
