I love this collection of notebooks, which have been used to record hundreds or even thousands of haiku. (The original post at Notebookers.jp is in Japanese, so I am relying on Google translate.) I don’t know much about Japanese writing and only know the most basic structure of haiku, but short poems with this kind of syllabic structure seem to fit very nicely on notebook pages like this!
