Japan may well be the land of the facial protruberances. I've seen more freaky moles, warts and skin bumps here than at any time in my personal history. I don't know exactly what it is, but you'll find warts and huge moles on people all over the place. Highschool girls who in the US would freak at the idea of having one of these dudes clinging to their epidermis casually apply their makeup around them. Old women and men seem to grow volcanic masses on their faces. Shane and i saw one in tokyo that was quite honestly the same diameter as a penny and about a centimeter and a half tall. It looked like something out of Hansel and Gretel or The Wizard of Oz.
It's possible that people here have the same occurrence of moles and warts as the western population and simply don't bother to get them removed. However, i find that completely odd because the japanese are incredibly image conscious, at least as conscious as Americans and probably more so. They also go to the hospital for the slightest health problem. For the common cold, that may require two or three visits to the hospital. My best guess is that the japanese must find them benign from a beauty standpoint, or at least not care about them too much. Maybe they even find that attractive, however far fetched that may be.
