Japanese and East Asians don't get as much body odor because they have less apocrine sweat glands so they don't need as much perfume, cologne, etc.

I don't really have too much of an issue myself as I grew up in North America but my cousin who lives in Japan used to complain about foreigners wearing excessive fragrances.
