My first japanese drama is "Zatoichi the blind swordsman". I don't remember which season exactly. I watched it very young, we still had black&white CRT (the color one was too expensive for our family) and I think I watched it in late 80's.
Gokusen if I remember well. I had seen pics/gifs of Gokusen 2, which made me interested in jdramas, but then I realised it Gokusen 2 was a sequel so I watched Gokusen first, which I liked very much as well :P
