In the pandemic's beginning, mask-wearing was taken up across Japan in the blink of an eye. "We've been wearing them for the three years since then," Yamaguchi said, adding, "It made me aware how people tend to base decisions on observing others, or put otherwise, how strongly peer pressure is rooted in Japanese society." Beyond mid-March, there will still be seasonal influenza risks, and hay fever season will continue. In addition to people's thought process, 'Let's see what others are doing,' this is the time of the year when masks are essential regardless of the COVID-19 pandemic. In Yamaguchi's view, many people will take this wait-and-see approach, and not stop wearing a mask right away.
