Japanese is traditionally written from top to bottom and right to left. However, there are also horizontal writing systems used by certain aesthetic movements in modern Japan. In general, Japanese characters are composed of two parts: a vertical stroke called a "haiku" and a base line called a "tori." The haiku can be made of one or more strokes. There are five main classes of strokes: plain (or cursive), en-stroke, em-stroke, boku-no-kubi ("parent's neck"), and shimo-no-torii ("low wall"). Plainer strokes are used for words that cannot be expressed clearly with just one character. For example, many Chinese characters are made up of plain components - strokes that do not form distinct images when viewed individually but which combine to make complete characters. Words that contain plain components are often spelled out in full when they appear in text. Cursive scripts are commonly found in humanistic cultures where reading and writing are valued intellectual pursuits. They are used because printed books were unavailable before the 19th century. Today, handwriting is coming back into fashion, so too does the use of cursive script.
