A few years ago I was running a Facebook page called Haiku Now. At the time somebody accused me of writing “desk haiku” because I wrote a haiku where I put a spider in an unnatural situation, or at least a situation that I could not have witnessed.
A debate followed with many comments. Only Michael Dylan Welch defended the poet’s right to use imagination in haiku (by this I mean setting up a situation as opposed to reporting on a moment of reality).
“[Haruo] Shirane was able to show that haiku (or haikai) was, essentially poetry of the imagination, that ‘the joy and pleasure of haikai was that it was imaginary literature,'” the book’s editors Lee Gurga & Scott Metz state in the introduction.
