Momiji is not an item. She is not an object.
In a country where coverage of women's lives and achievements is hardly equal to that of men’s, where pictures of women scientists, writers, and thinkers rarely appear in the popular press, we are awash in photographs of anonymous young women, selected and pictured to sell products, attract attention, and please male viewers.
Magazines like Playboy claim to be "celebrating women's beauty." But Playboy doesn't run pictures of... Women... Of female human beings of all ages and sizes, of the women who make up more than half of our population. What Playboy does in fact is to "celebrate" one minutely small portion of the female gender. They are usually "models:" young, VERY PRETTY women of a physical type chosen to appeal to male eyes.
But even these "highly selected and carefully chosen" young women are not presented as full and multi-dimensional people; instead, they are often posed and dressed so as to de-emphasize individuality. The effect visually reduces a woman to a body, or in some instances, to parts of her body, as if she is not a real, whole person.
The term that most often describes this phenomenon is: objectification.
