Waka != Haiku

I did not quite fling this book across the room in disgust, but it came very close:  

A cloud of blossoms
A hazy moon
Tast of mist, sweet wind

That is my waka for the spring tea that I plan for Auntie and my mother.  It is modeled after the greatest of the ancient Japanese poets, Basho.  His was better.

                            The Royal Diaries: Kazunomiya, Prisoner of Heaven, by Kathryn Lasky, p. 15

A waka is a classical Japanese poetic form of 31 syllables arranged in five lines. The Kokinshu (905 C.E.) is the first collection of waka only.  Kazunomiya would certainly have been familiar with it, as well as with later collections such as the Hyakunin Isshu, and would more believably have referenced such poets as Ki no Tsurayuki, Izumi Shikibu, or just possibly Saigyo.

An haiku is a later Japanese poetic form of 17 syllables arranged in three lines.   Crudely speaking, the haiku grew out of the first part of waka and came to be a standalone form.

Basho (1644-1694) was a master of haiku, not waka.  In a country with extant diaries reaching back to 600 years before Basho (Tosa Nikki, 934-35, oldest surviving diary written in the Japanese language), and extant literature from the early 700s C.E., Basho would hardly have qualified as ancient to Kazunomiya. 

I grant that historical fiction takes certain liberties with facts in order to create a more engaging story.  But unnecessary ignorance of even the basics of Japanese poetry styles, in a tale where such poetry is an absolutely key cultural underpinning?   When a wealth of material exists, beyond Basho? The author has been unforgivably lazy with this story.
