I want to watch a great Japanese drama 
Last drama I watched was  Karamazov no Kyodai and it was wonderful
I want one as same as it  and new from year 2015 .... or more

I assume you like thriller and dramas with psychological bent? If you're looking for those, I'd recommend these dramas (they're all from 2015-onwards):

- Yume wo Ataeru
- Garasu no Ashi
- Kageri Yuku Natsu
- Yami no Bansosha-

Anything from the channel WOWOW is worth checking out, really
