Thank you for a very interesting question.
Well, I'm not sure whether Asians should shower less frequently!
However, it is true that they have less body odor than other races.
The reason for this is not bacterial related but is caused by the
amount of apocrine glands they have in their body. Asians have fewer
apocrine glands than almost any other race.
Apocrine glands, which produce scents that we commonly refer to as
body odor, vary widely among the races. Asians have an extremely low
distribution of apocrines (Koreans are among the least odor-producing
people on Earth50% of them have no apocrine glands at all). With
regard to other races, blacks have a slightly higher distribution of
apocrine glands than whites.

It's not that Asians don't have sweat glands under their arms; the
difference is that they have markedly fewer apocrine glands than black
or white people. That doesn't mean they sweat less--eccrine glands,
the other main type of sweat gland, are a thousand times more numerous
on most bodies, and Asians have plenty of them. But apocrine glands
are the kind that make you stink.

Asians, on the other hand, tend to have smaller and far fewer
apocrine glands than either Caucasians or blacks, and many have none
at all. In fact, only about 10% of Japanese people have any underarm
odor at all, and at one point having scent glands in the underarms
qualified a Japanese male for a military exemption and a free ticket
to a medical center where they could receive treatment.

Men have more androgen and bigger apocrine glands, and they stink
more. Unless they are Asian men. Asians have few apocrine glands. In
Japan, B.O. is considered a medical problem--enough, in the past, to
merit exemption from the military.
