Okay, so this is my first time watching japanese dramas and can you guys give me some recommendations? Which jdramas are a must watch for beginners?

I guess it also depends on your favourite genre. I like things with some psychological or sociological stuff but I don't know if that's good for a beginner per se. I'll just recommend some I liked:
  • Itazura na Kiss - Love in Tokyo
  • LIAR GAME
  • Orange Days
  • LIFE (currently watching)
  • Mother
  • Rich Man, Poor Woman
Good for newbies:

Hana Yori Dango
Itazura na Kiss Love In Tokyo
Hana Kimi or Hana Kimi Remake (I personally liked Remake better)
Akumu chan
Last Cinderella
Ouran High School Host Club
  • Hana Kimi - gender bender, school

Light-hearted comedy dramas :-
  • Boku to Star no 99 Nichi - korean actress goes to japan
  • Priceless - salaryman becomes jobless 
  • Nobunaga Concerto - time travel to history
  • HERO (2001) - unorthodox lawyer
  • MR. BRAIN - genius forensic scientist

  • Siren - Crime, Detective, Romance, Suspense, Thriller
thank u so much sweeties!!
