While some may assert that the Japanese live about as long as humans, recent scientists have found this not to be the case. The Genus Japanalia and the many species of Japanese are comprised of cells containing 45 chromosomes, one less than human's contain. This missing piece is known as the "soul chomosome", and its absence enables the Japanese to live to extremely old ages.

To answer your question more directly: Ancient Japanese have been known to live over 8000, maybe even 9000 years.
