Don't know what a haiku or waka is?
Haikus and wakas are two types of Japanese poems that either have 3 lines of poetry(haiku) or 5-7 lines of poetry(waka). You simply decide where to change line of poem.
Example of haiku:
Serenity –
plum flowers
falling on the koto
(koto = probably a Japanese instrument)
[This is what I collected from Swedish wikipedia, correct me if I'm wrong somewhere.
While I'm still here, I can write my own waka down:
Let time flow
Let time play
Your time
will always
be restored
