Yeah, and his female characters are some of the best in shonen jump in my opinion. The mothers aren't treated as just mothers. They're allowed to have personality and backstory. Otohime, Portgas D. Rouge and Bellemere are examples of this.
As much as I love JJK, Megumi's mom doesn't have anything to her character besides being the person who just so happened to give birth to Megumi and I think this lack of confidence in writing women is reflected in how much there is to be desired with his other female characters.
Likewise, as flawed as Naruto is with its female characters Kushina IS allowed to have a personality and be more than just a wife and a mother.
There's obviously nothing wrong with having a female character that's tied to motherhood and is nurturing but when that character isn't even given a name in the text of the story and isn't able to be seen as anything but a mother what exactly are we supposed to take away from that?
I feel like you can tell a lot about how an author views their female characters based on whether or not they give dead mothers a name.
