I didn't know Screen Red by HBO also airs TV drama series. I only found out now. Remember to buy DVDs or stream it legally. I read that Netflix also has a limited Asian drama series.
But also support the mangaka by buying the manga published in English.
31. Nodame Cantabile by Ninomiya Tomoko
It was serialized in the magazine Kiss. The 23 volumes manga was published by Kodansha and Del Ray Manga in English. It has been adapted into three seasons anime, covering the whole plot of the manga.
The first TV drama was broadcasted in 2006 on Fuji TV, a year before the anime was aired. The 11 episodes was starred by Ueno Juri and Tamaki Juri. A 4 episodes special showing Nodame and Chiaki in Paris was aired in 2008.
There was also a loosely adaptation South Korean drama starring Joo Won and Shim Eun Kyung. It was aired in KBS2 on 2014. I don't recommend Cantabile Tomorrow or Naeil's Tomorrow if you're a fan of the original plot but if you're a fan of Joo Won or any other character like Park Bo Gum (I watched it because of him after seeing him in I Remember You), why not.
