Chimney

The Chimney is a room humidifier.... the air gets very dry with air conditioning and also in Japan its extremely dry so something like this will help your throat, nose, and general feeling.

The good thing about this one is that it also has a cool design unlike most of the horrible little box ones you can get in electric shops.....

The tank holds about two litres of water which will keep it working for about 8 hours... not that I need to leave it on for 8 hours, my house fills up with a cool water mist hanging in the air...its interesting but you have to be careful that you don't raise the humidity too much, otherwise you can get mold and other nasty bacteria growing everywhere...
