Kanjis

I love studying kanjis.

Why do so many people study Japanese? The kanjis aren't logical, there are two alphabets, there aren't spaces between words, the adjectives change with the tense of the sentence, there are various grammatical constructions for the different levels of formality.

All is written in shaky kana letters, only with one or two kanjis, i.e. the Chinese letters.

Because the standard vernacular writing system of Japanese makes no use of spaces between words and because kanas (syllabic Japanese characters) and kanjis (ideographic Chinese characters) are used instead of Roman letters, it is necessary to devise a method of automatically cutting into its components the unsegmented sentences, written in kanas and kanjis.
