This article looks at the history of mask-wearing in Japan, its current situation and why masks are still required there. It also discusses whether masks are necessary outside of Japan and the benefits of wearing a mask. Tips on how to properly wear and care for a mask are provided, as well as references/sources. The primary reason why masks are still required in Japan is because they help prevent the spread of infectious diseases such as COVID-19 by trapping droplets expelled when speaking, coughing or sneezing before they can reach another person's nose or mouth. Wearing a mask also provides psychological benefits by allowing people to feel safer when going out into public spaces and helps remind people to maintain social distancing guidelines.
