A major difference in personal grooming in Japan and my home country

Today, and November 20th annually, is "A day to support men's hair removal" in Japan. I have a teenage son. I began to notice the difference in how teenage boys and men groom when in Japan last year. But now that I am in my home country, Ireland, I have been able to confirm that the differences still exist in contemporary society. That is, in Japan male hair removal is far more popular than in Ireland.

It would seem hair removal is influenced by a perception in Japan that it is more hygenic, but in the West it is not inherently viewed as good hygiene and some believe that hair has a protective purpose. There are other influences in Japan too.  For example, a soccer coach in Japan told my son to shave his legs, because if he needs to tape his legs (for muscle support) it's much more painful if you have hair on your legs. It doesn't bother the kids in Ireland! Boys / Men in Ireland generally don't shave their legs, even if they play sports. There are, of course, exceptions.

Eyebrows is another area that some teenage boys / men in Japan use hair removal products on or procedures for. Again, in my home country, it is quite unusual for a man / boy to pluck his eyebrows. Each to their own. I am just pointing out cultural differences regarding hair removal. Do you if hair removal is common among boys / men in your home country?
