Long ago, poets in Japan listened, watched, and caught the beauty of the earth's songs like the raindrops. They did this with the tiniest poems in the world, called haiku. A haiku is a poem that is just three lines and seventeen syllables long. And the poets who wrote them watched and listened, not only with their eyes and ears, but also with their hearts!
In their haiku, the early Japanese poets caught the colours, sounds, and beauties of the seasons of the year. They sang of their islands' beauties. Their miniature poems were not meant to fully describe a scene or to explain it but rather were a flash impression.
Interestingly enough, Japanese poetry has had a long and colourful history. In the prehaiku period in the early eighth century, Japanese poets wrote katauta, poems in a question-and-answer form, using two people. Each three-line verse contained about seventeen syllables that could be delivered easily in one breath—just as one would naturally ask or answer a question. This has remained the basic pattern for traditional Japanese poetry throughout the centuries.
Another form that appeared was the tanka, which contained five lines and thirty-one syllables(5, 7, 5, 7, 7), written by either one or two persons. From that evolved(逐步形成) the renga, which contained more than one verse, or link. Written by three or more people, it could have as many as 100 links! The first verse of the renga introduced a subject. It had three lines and was called hokku, or starting verse. Renga parties became a great pleasure.
Around 1450, haikai no renga became popular. This style of linked verse contained puns (双关) and was humorous and amusing. The opening three lines were still called a hokku, and from haikai and hokku the term haiku evolved.
