Hello, I just wanted to add four dramas that I like a lot. It's better if you watch the trailer before, for see if it can please you ;)
https://mydramalist.com/2988-nobuta-wo-produce I watched it 10 years ago, and really liked it, it's a school drama about a popular guy who is a little hypotrical and one of his classmate who is eccentric, both they want to help a gloomy girl, Nobuko to make over. It's a touching story about finding yourself through friendship and go through the hardship together.
https://mydramalist.com/151-dragon-zakura I watched it a long time ago, not sure if it aged, it's a school drama about a lawyer who wants to send his students at the best university in Japan. His students are misfits and really bad students, it's a story about friendship, and surpassing oneself, it's a motivating drama !
https://mydramalist.com/23-kimi-wa-petto A beautiful and brillant woman takes a young man like a pet at her home. Some people prefer the modern version if you want to check it (I didn't watch it). It's a funny drama with brillant leads that talks among others topics, about the place of women in society.
https://mydramalist.com/26147-you-always-inhabit-my-heart It's a sad romance, be careful because with the ratings, I think there are few people who like it. It's the story of Kyoko, a young woman who lacks of confidence and wants to look ahead with a nice man that she met at a speed date party. But she is caught up by her difficult past when her abusive ex boyfriend comes at her company for work. With this drama I understood better one of my friends who dated an abusive man and couldn't left him during a long time. All characters are nuanced.
I just add this japanese movie because it's not in your list and I like so much this director:
