Yes.

On average white guys are physically more masculine than East Asian guys, like the Japanese.

East Asians have something called neoteny which is the retention of child-like physical features. So they don't change as much from childhood into adulthood or teenage years as do other races, like white people.

East Asians are typically short as well, which is not masculine. White guys are the tallest on Earth which is masculine (along with black guys).
