Movies or TV Shows about Mothers?

[FiercestCalm]

Hey,
I'm writing a thesis about the portrayal of bad (violent or negligent) mothers in Japanese media. Does anyone know of any Japanese movies or TV shows that feature these kinds of mothers?
Thanks!

There is this movie, about a mother whom leaves their children alone at her home... The movie is more about the children than about the mother... but it shows the problems in Japan and how to raise children:

Nobody knows.
