Old Japanese

Old Japanese (上代日本語, Jōdai Nihon-go) is the oldest attested stage of the Japanese language, recorded in documents from the Nara period (8th century). It became Early Middle Japanese in the succeeding Heian period.

Old Japanese is an early member of the Japonic language family. No genetic links to other language families have been proven.

The bulk of the Old Japanese corpus consists of poetry, especially the Man'yōshū, with a smaller number of formal prose works. These texts were written using man'yōgana, a writing system that employs Chinese characters as syllabograms or (occasionally) logograms. The language featured a few phonological differences from later forms, such as a simpler syllable structure and distinctions between several pairs of syllables that have been pronounced identically since Early Middle Japanese. The phonetic realization of these distinctions is uncertain. Internal reconstruction points to a pre-Old Japanese phase with fewer consonants and vowels.
