okay! sorry i wasn't able to immediately reply.
the reason i like yamada sensei is because her ukes are mostly empowered bottoms and won't take into sitting any bullshit given to them. in terms of really popular mangakas here, she's totally underrated. also, what i like about her is she has the tendency to make spin-offs of her minor characters and give it a charm of it's own.
anyway, for starters, try reading her most popular manga Saigo no Door wo Shimero! it got so popular it's made into an anime movie.
Taka ga Koi daro - a childcare manga. it's adorable and cute. seme is so handsome. it's connected to aiso tsukashi, her most popular work here in mangago.
Darenimo Aisarenai - with the right feels. all the heartache and the doki-doki love. slice of life. reencounter. and if you're a book lover you'll appreciate this one.
Where can i findf all the chapters of Koibito Kijunchi..?
