Not sure if these suit your taste but I'll just list down those that left quite an impression on me for the past year.

Human/slice of life dramas:
Tenno no Ryouriban - prepare tissues for this 
Mondai no Aru Restaurant - I like how they describe women's position in men's world and the characters are charming in their own ways.
Kazokugari - very dark/heavy insight into family issues
Wakamonotachi 2014

Detective dramas:
Ouroboros
Border
Ishi no Mayu
Tantei no Tantei

Other recommended ones:
N no Tame ni - quite heart-warming and about a group of friends with a dark past
Alice no Toge - revenge suspense

There's HERO (2014 version) too if you're interested.
