  • There are no kana for Ye, Yi or Wu, as corresponding syllables do not occur in Japanese natively. The [je] sound is believed to have existed in pre-Classical Japanese, mostly prior to the advent of kana, and is generally represented for purposes of reconstruction by the kanji 江, although an archaic hiragana ye, 𛀁, does exist. In later periods, the syllabogram We came to be realized as [jɛ], as demonstrated by 17th century-era European sources, but it later merged with the vowel E and was eliminated from official orthography in 1946. In modern orthography, [je] may be written いぇ, イェ.

History

The first kana was a system called man'yōgana, a set of kanji used for their phonetic values, much as Chinese uses characters for their phonetic values in foreign loanwords today. Man'yōshū(万葉集), a poetry anthology assembled in 759, is written in this early script. Hiragana
