Kigo (季語, “season word”) is a word or phrase associated with a particular season, most often used in traditional forms of Japanese poetry such as haiku, renga and renku.

Wikipedia provides an excellent definition of haiku:
“Haiku is a short verse genre written in one line in Japanese and commonly three lines in English and other languages. It has achieved significant global popularity, having been adapted from Japanese into many other languages. Typical of Japanese haiku is the metrical pattern of 5, 7, and 5 on (also known as morae). Other features include the juxtaposition of two images or ideas with a kireji (“cutting word”) between them, and a kigo, or seasonal reference, usually drawn from a saijiki, or traditional list of such words. Many haiku are objective in their depiction of personal experiences.”
Wikipedia.com/haiku
Most haiku written today still follow the ancient tradition by including a kigo. Be aware that most haiku groups and editors of haiku publications insist that haiku should include a kigo. I’m a traditionalist, so anything that does not have a kigo is something else, either senryū or zappai (miscellaneous haikai).
A saijiki (sigh-gee-key) (歳時記, lit. “year-time chronicle”) is a list of kigo (seasonal terms) used in haiku and related forms of poetry.

The following list has been quoted from: Yuki Teikei Haiku Society. I’m not sure that this site is still functional, as many of the site links go to 404 pages. The links below will take you to the site.
The Yuki Teikei Haiku Season Word List
Haiku Seasons
“These season words or kigo are from the 1977-78 Haiku Journal. Originally the list was selected from Japanese saijiki (kigo “dictionaries”) and translated by Kiyoko Tokutomi. Over time words have been added that have seasonal resonance for our predominantly North American members. We present these lists as a guide and aid to English-language writers who want to think about this aspect of haiku in their own writing, as well as in appreciating the haiku of other poets.”

* In Japanese haiku, many phenomena of July and August are traditionally considered autumnal: for example,Tanabata (in early July), Obon (in early August), the Milky Way, and morning glory are autumn kigo. In the Haiku Journal, they were listed in both seasons in consideration of non-Japanese poets for whom these topics unambiguously evoke summer feelings. In this list, we defer to the traditional category, to avoid confusion. | |

Wikipedia.com also has a kigo word list with the Japanese names HERE. This is an amazing list!
This should be enough to get you started on your haiku writing journey. ~Colleen~
So, creating a poem around one of those animals or plants would be considered a kigo? I thought it had to be a word that stated a season. I’m learning a lot. Thanks, Colleen! 🙂

We’ve all been writing haiku wrong. The Japanese Masters say that Western haiku is destroying the form. That’s why we need to learn how to write it correctly. I’m still learning too… ❤

Are the Japanese masters saying that Western haiku is destroying Japanese haiku–or just that Westerners are doing it wrong?

“Contemporary Japanese haiku master Akito Arima has lamented that we now live “in the age of zappai.” This stems from the ideal that haiku is Zen and Zen is haiku. Westerners do not know how to write haiku. Get the book, “Haiku: A Poet’s Guide” by Lee Gurga with Charles Trumbull. This book totally opened my eyes!! ❤

From what you’re saying, it sounds as though genuine haiku stems from living in the world a certain way–and the strict conventions of the form enable a poet to do that. Very interesting!

I think there sounds too restricting… It’s more about observing the world around you. It’s finding the connections between things we wouldn’t normally see. The Zen part is cultural, but I don’t imagine that everyone connects that way. We must train our senses to find those juxtapositions and comparisons. It’s not exactly a Western concept, but we can learn.
