Books about cats
Japanese people, speciallly Japanese women, love pets. The more kawaii (cute) they are, the better. When you meet a Japanese woman the first thing they often do is to show you a picture of their pet, which they usually have as a wallpaper on their cellphones. Apart from the usual dog books section, the other day I saw a special cat books section. The incredible thing is that most of the books only include pictures of one cat posing and doing different activities.
