HOW TO: Find (good) deodorant in Japan

If you're coming to Japan, you will probably hear someone lamenting about the inability to find any "real" deodorant here. When I heard this before coming, I promptly bought a 4-pack of my favorite kind (which I still haven't used up, two years later). Yet, for those trying to save luggage space, unless you are REALLY attached to your deodorant, let me reassure you, it IS possible to get deodorant in Japan. And no, I'm not even talking about typical Japanese stuff, although chemically, it isn't really different from the stuff you're likely already using.

HOW TO: Return an Item (to a Store)

Ever wonder what to do with something you ordered or bought here in Japan, but realized soon after that it doesn't fit, or work, or something else undesirable?

I had this problem during my first years here, when I accidentally bought something that didn't fit or realized I actually didn't want what I had bought after a couple days. Every time I asked someone how I could go about doing a return, yes even those who speak Japanese, they didn't know what to do. They had never done it before, they said. Maybe it's just me, but I'm a buy it and try it kind of gal. And call me strange, but I'm also far too lazy to try on clothes at the store, and do my best to guess the size (which explains my inclination to shop online). Usually, these tactics are successful. But on the rare occasion that something just doesn't fit, (or you later decide you hate it, or maybe shouldn't have spent that much money on it), what to do?
