Hi there! I will be visiting Japan in 2 weeks and have been extensively looking for a new electric shaver. I've settled on the ARC5 and was considering buying through Amazon (in Ohio) but was wondering if it would be different than the one made in Japan? I have heard that there is a new 3rd generation foil that you can buy but does it come standard on the ones in Japan? Or would I have to buy the foil separately? My only gripe is if I buy it in Japan, I wouldn't be able to return it (if I dislike it). Thanks.
