Any tearjerking japanese dramas?

Question:

im in a rather sad mood so i feel like watching something that would make me cry - sad right?
any way so far i've seen:

proposal daisakusen <3
tatta hitotsu no koi ;')
taiyou no uta <3 <3
1 litre of tears :'(
and
boku no hatsukoi wo kimi ni sasagu - not a drama but one of the best and most sadest movie i've seen :'( <3

thanks

Answer:

There's a movie kind of like Taiyou no Uta called Koizora. It's very, very very sad.

There's a drama called Hana Kimi. It was horribly sad for me only because I wanted a certain couple to happen that didn't happen. If you aren't into that couple, it's just a heartwarming story. You'll still probably cry, though.
