A haiku is a Japanese poetry that generally consists of three brief lines that do not rhyme. A haiku is more than just a style of poem; it is a means of looking at the physical world and understanding something deeper, such as the basic nature of existence. It should evoke powerful feelings or impressions in the reader. The form itself encourages this, because it limits the number of words that can be used per line. Hi Q poems are a type of haiku that use the numbers 1 to 9 instead of the typical 5-7-5 syllable count. They were first popularized by Masaoka Shiki who included them in his book Haikyu (The Art of the Brush). Like traditional haiku, hi q poems focus on the ephemeral beauty of nature and human life, but they do so by using digits instead of flowers or birds for inspiration. The term "hi" means "one," "two," etc. ; thus, a hi q poem contains one unit, two units, etc. Until the early 20th century, these poems were usually anonymous; only since then have some authors started using their names instead.
