I only know a tiny corner of the language, but for things like this I really wish they'd cite the original Japanese. Precisely because the haiku is a constrained form, it is also an opportunity for ambiguity, double-meaning, and cases where a word may be translated with the same semantics but different connotations.

By comparison, the gold standard for dealing with non-English poetry in English: https://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1...

You have (1) the original Greek, (2) word-by-word lookup, (3) translation notes, and (4) multiple translations.

Agree 10,000 fold. English and Japanese are so different and have such different standards of aesthetics and literary form that good translations are like independent creations inspired by the original. I would like to know that the original form was. Even a word by word ungrammatical transliteration would be helpful. But not to have the Japanese available means I cannot even look it up...
