Title: Big in Japan
Description: In Japan, they don't usually have central heating, so it can be tough to keep warm in the cold weather.  One way to keep warm is with "kairo," little heating patches that you can stick on your body.  The author talks about her favorite brand, Mr. Hot, some of its ingredients, and where under her clothing she likes to put them on.
