The culture of collaborating Young girls and Middle age guys

Do you know the Japanese culture of collaborating Young girls and Middle age guys.
Just now, those cultures bloom so much in Japan.
Young girls passion plus middle age guys experiences made big cultures.

But Japan, over sixty year-old people world has no culture, no happiness.
VERY TERRIBLE.
