On the tone of JapaneseAbstract From the current teaching and learning situation of Japanese tones ,more and more attention has been paid to the tone of the Japanese language. Both the breadth and depth of the content of the study, the overall level of research has been greatly improved. At present, for Japanese learners of textbooks and dictionaries and other tools, although has many methods about Japanese words tone, but it did not give a simple and quick way to the law. With the increase of the content of the study, the diversity of the tone change is also more obvious, the vocabulary is increasing, also the structure of the article is more complicated. Rely solely on the primary stage that a simple rote learning and traditional learning methods have been difficult to solve practical problems that often arised in learning. How to correctly grasp the tone pattern, so as to improve the learning efficiency, this is a problem that Japanese learner must be solved . All of the known language in the world in their words have higher or heavier parts in pronunciation, phonetic or phonological learning to read these traditional high or heavy read parts called rereading. Stress in different languages have different forms of expression, and some are reflected mainly in the strength . The tone of the Japanese is to demonstrate the pronunciation of the type of n+1, the different types of pronunciation have different corresponding pronunciation rules.Key words：Tone , overview , type ,rule1 Tone and type of tone 1.1what is the tone ? The tone is a syllable of the height of the lifting form,it is mainly determined by the pitch. The musical scale is also determined by the pitch, can be used to simulate the scale, learning can also be used in the tone of their musical sense. But note that the pitch of the tone is relative, not absolute; the change in the pitch of the tone is sliding, unlike the jump from one scale to the other. Tone of the height is usually marked with a five degree method: vertical mark, in 5 degrees, the minimum is 1, the maximum is 5. Mandarin has four tones: Yinping Yangping, shangsheng, Qusheng. 1.2 Tones are generally divided into several kinds Strong and weak - English ,High and low type - Japanese and Chinese .The tone is called tone type. The tone category is concluded according to the actual pronunciation of tones, the same tone is a tone. Mandarin has four tones, namely Yinping, Yangping, Shangsheng and Qusheng, referred to as four sound. Available value five notation to describe the sound of four. First , YinPing :The highest pitched voice, high and flat, from 5 degrees to 5 degrees, with no changes, usually called the high tone or 55 tone, such as“spring flowers”. Second , Yang Ping: From the sound is not high to the alto voice from the treble, from 3 degrees to 5 degrees , usually called the high rising tone, rising tone or 35 tone, such as the unity of the people.Third, Shangsheng: From the sound low, then reduced to the minimum, and then rise to half, from 2 degrees to 1 degrees and then rise to 4 degrees. If the rose after the first drop tone, often referred to as falling rising tone or tone, such as perpetual friendship.When one tone connected with the other tones in tone with or connected, should read the change tones. First, read half - tone, tone in the Yin Ping front should read half tone, from 214 to 21 or 211, is falling, because the begin sound is low, so low level approximately . Second, read straight, like the same tone with the tone .From 214 to 24 or 35 toneForth,Qusheng read high down (or full drop), since then the pitch, sliding down,represented by the five degree mark method, is reduced from 5 to 1, writing 51. To complete relaxation of vocal cord tight, sound from high to low, the length is the shortest.2 The characteristics and functions of Japanese tones 2.1 The difference of Japanese and Chinese tones We should note that the Japanese pronunciation of words is relatively simple, in addition to bend sound, each under a pseudonym for a beat (Note: This includes long tone, dial tone and promote sound). When you read the words in a pseudonym, a pseudonym to read, not lost anyone, here also includes a long tone, dial tone and promote sound. Such as: mother in japanese have 5 syllables , there are long tones and a dial tone; And money in japanese have three syllables . Must be correct the pronunciation, so as to remember accurately. Because of the difference in pronunciation, the meaning is likely to change, or even a completely different word. So how to grasp the tone? This depends on the tone of the core.For example: janpanse rain choptistics end. Although the Japanese and Chinese people speak the language are completely different, But the Japanese writing system comes from Chinese. Chinese writing in five.Introduced to Japan in sixth Century.The body of Chinese writing has been added.Japan still has many local dialects. In suc
