Then we have the very important hot hand towel warmer. In the winter in Japan, whenever you go to a restaurant, or even sometimes to a friend's house, you will be handed a hot hand towel. In a good restaurant they will be real cloth. In a cheaper restaurant they will be made from a soft paper. In either case, they will be heated so of course, you need one of these warmers! Here is a tip if you travel to Japan, don't do the "ojisan" (old man) thing and wipe your entire face with the hot towel while sitting at the table....it isn't cool!
The last gadget for today is the canned drink warmer. I have to admit, it is very cool to be able to get a hot drink where ever you are. This is obviously for a house or a small store but the whole hot canned drink thing is pretty amazing in Japan. I mean, you can be in the middle of nowhere yet there will a vending machine filled with hot drinks, hot corn soup (think creamed corn), pudding in a can etc. Well, if that appeals to you, you can buy this and always have a hot drink (or corn soup) ready to drink!
