Senryu (also called human haiku) is an unrhymed Japanese verse consisting of three unrhymed lines of five, seven, and five syllables (5, 7, 5) or 17 syllables in all. Senryu is usually written in the present tense and only references to some aspect of human nature or emotions. They possess no references to the natural world and thus stand out from nature/seasonal haiku.
