There are four dominant Y chromosome macro-haplogroups in East Asia - O-M175, C-M130, D-M174 and N-M231 - accounting for about 93% of the East Asian Y chromosomes. The other haplogroups, such as E-SRY4064, G-M201, H-M69I-M170, J-P209, L-M20, Q-M242, R-M207 and T-M70, comprise roughly 7% of the males in East Asia. Haplogroup O-M175 is the largest haplogroup in East Asia, comprising roughly 75% of the Chinese and more than half of the Japanese population.
