Some people think it can be classified into Altaic language family, while some Japanese scholars think it is isolated language, Fuyu language family or Japanese language family.

The complex writing system of Japanese is one of its major characteristics. Its writing system includes Japanese characters (most of them have two pronunciation and training), Hiragana and Katakana, and can also be transcribed from Roman to Latin letters. In terms of phonology, apart from the pronunciation of and the dialing of, the open syllable language has strong characteristics and has a mora. In terms of stress, it belongs to pitch accent. In terms of word order, sentences are composed of the order of subject, object and predicate, which belongs to the structure of subject-object-predicate and is one of the representative topic-first languages. Morphologically, it belongs to adhesives.
In terms of vocabulary, in addition to Heyu, which has been handed down from ancient times, there are also Chinese characters introduced from China. Recently, the proportion of loanwords introduced from different countries has gradually increased. On the other hand, Japanese is very changeable, not only in spoken and written language, but also in common and solemn, male and female, old and young, and developed honorific system. In the part of dialect, there are great differences between eastern and Western Japan, which is called Guandong dialect and Guanxi dialect. In addition, for deaf people, there is Japanese sign language corresponding to Japanese grammar and phonological system.
