In fact, a lot of Westerners (including me, who am an American) may be surprised to see famous idol groups in Japan, say, something-zaka 46.
For their appearances, especially those of the most popular members, are clearly more similar to those of Caucasians than average Japanese girls are. It is obvious that this is a reflexion of the general taste of Japanese boys.

However, what's more weird than surprising to us may be how different they are in inward character from Western women, in spite of their appearances.
They usually behave themselves like obedient and weak women who incline many men to protect them. Their appearances and behaviours might help us to imagine what women in mediaeval Europe were like.

The above facts prove that Japanese men still have the awfully old-fashioned sexist idea. There may be 60 million MORI Yoshirōs in the Japanese Islands.
