Some JAV codes to look into that have either a large focus, or focus completely on milf age performers or milf dramas/scenarios:
VEC
VENX
ALDN
LUN (mostly uncredited)
OBA
JRZE
JUR
DASS - has a subseries called 'my girlfriend's mother is more appealing to me' and others like it

Some other idols that get cast in mommy roles but may not necessarily be known for their mommy content:
Hana Haruna
Miki Akai
Nene Tanaka
Chitose Saegusa
Ruri Saijo
Waka Misono
Ai Sayama

And if storyline driven content isn't your thing and you just want to see Japanese mommies get pounded there's compilation re-releases like NASK-195 that snip anywhere from 4 to 20 random scenes from a studio's library that fit a theme 'chubby asian milfs fucking cowgirl style vol. 9'

Pic is a recent one I enjoyed starring Ritsuko Hanayagi called:
KEED-87 When I Looked At My Boyfriend's Phone, I Saw Him Having Intense Sex With My Mother.
