Every pseudonym in Japanese represents a syllable (except a groan), so it belongs to syllable letters. There are 71 pseudonyms in Japanese, including voiceless, voiced, semi-voiced and dial tone. There are five basic vowels, 4 1 consonant, and four can't spell. Pseudonyms representing 45 unvoiced syllables can be arranged in a table according to pronunciation rules.
The vertical direction of the table is called "segment", each segment has ten pseudonyms, and * * * has five segments. The horizontal direction is called "line", with five pseudonyms in each line and ten lines in * * *.

The basic unit of Japanese pronunciation is the beat expressed in Hiragana. Therefore, Japanese is called a phonetic language (Mora), while Chinese is a syllable language (syllable language). Every beat is a vowel or consonant+vowel. There are five vowels, namely "ぁぃぅぇぉ", "かきくけこ" and "さしす".
However, there are two exceptions. One is "ん"/n/ n/ and" っ"/q/ q/ ",both of which have only consonants and no vowels. In addition, "ん" is difficult to pronounce alone, and "っ" cannot be pronounced alone. But the length of their pronunciation is one beat at a time. The other is "きゃ, きゅ, きょ", which is composed of /kya//kyu//kyo/, that is, "consonant +y+ vowel", which is a pronunciation from ancient Chinese.
The Japanese tone is the position of the beat. It doesn't change high and low in a syllable like Chinese tones, and there is no difference between high and low words in a beat in Japanese. For example, according to the Tokyo tone, there is no difference between "Sun (ひ)" and "Fire (ひ)".
However, if the subsequent auxiliary word "が" becomes two beats, "が" and "が" will be different according to the Tokyo pronunciation.
