Haplogroup C-M8 also known as Haplogroup C1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup C1a, one of the descendants of Haplogroup C1. The other is C1a2.

It has been found in about 5% of males sampled in Japan.^[4] Elsewhere, it has been observed among academic studies only in one individual in a sample collected on Jeju Island of South Korea^[5] and in commercial testing in one individual who has reported an origin in Liaoning province of China and one individual who has reported an origin in Seoul, South Korea.^[6]

The MRCA with the closest sister haplogroup C-V20 dates back to 40,000^[1] to 50,000^[2] years ago. As long as grasped by current research, diffusion of the existing subtypes of C-M8 is estimated to be about 12,000 years ago.^[3]

Frequency in Japan

Tokushima 10%^[3]
Okinawa 6.8% [4.4%^[7]-8%^[8]]
Honshu 4.9%^[7] (Aomori 7.7%^[3], Tokyo 7.1%,^[2] Shizuoka 4.9%^[3])
Kyusyu 0%^[3]-3.8%^[7]

History

Migration of Haplogroup C (Y-DNA)

Haplogroup C1a1 (M8) is mostly unique to the Japanese archipelago, and its migration route is enigmatic. The closest sister Haplogroup C-V20 is discovered in Paleolithic Europe (Cro-Magnons), Neolithic Europe and modern small numbers of Europeans and North Africans etc. A little further, it reaches the common ancestor C1 with C1b1 (M356) which is found in India and Arabia etc and C1b2 (B477) which is often found in Melanesia, Polynesia, eastern Indonesia and Indigenous Australians. Mitsuru Sakitani said that C1a1's ancestral type reached Japan via the Korean Peninsula via Altai Mountains from South-west Asia^[9]. Although its age of arrival is unknown, the spread of the existing subgroup is about 12,000 years ago, which is almost consistent with the start of the Jōmon period. That is, Haplogroup C1a1 may be a group that brought Jōmon culture to Japan.
