No clue. Maybe she's just that short

Depends on her height. Probably not an ideal weight for the average Japanese woman?

Though Kuroki is right; diet is important, but exercise is probably moreso. I mean, you need both, but burning more calories than you take in and building enough muscle to burn said calories is critical.
