Jdrama recommendations

Until now I've been watching kdramas almost exclusively. I want to branch out to jdrama now. I love romance, fluff, melodramas. Police shows are okay too as long as they aren't too dark and gritty. I also like shoujo manga/anime adaptations. See my list to get a better idea. What would you guys recommend?

Light-hearted police dramas:

Odoru Daisousasen

Mr Brain

Bitter Blood

I also second the recommendation for Bitter Blood and Kekkon Dekinai Otoko.

Kekkon Dekinai Otoko is creme de la creme :)

here are my recs

you decide the genre

Definitely watch Buzzer Beat

Also the classic:  Nobuta Wo Produce

Not entirely fitting your description, but I recommend this drama to anyone who want to watch a  Japanese series, as it is my favourite. It is called Kazoku Game.
