Haiku poems date from 9th century Japan to the present day. Haiku is more than a type of poem; it is a way of looking at the physical world and seeing something deeper, like the very nature of existence.A haiku poem consists of three lines, with the first and last line having 5 moras, and the middle line having 7. A mora is a sound unit, much like a syllable, but is not identical to it. Since the moras do not translate well into English, it has been adapted and syllables are used as moras.
