I really do not enjoy wearing mask for 8~9 hours on the plane.
Also, I was expected to wear mask when I was in Japan and Korea.
It may help but I do not want to go places where you need to wear mask.
That is one of the reasons why I really considering not to go to Japan next month.
The temperature is still just above freezing in the morning but cherry street are blossoming in Tokyo. The buliding on the left was where I needed to go on the meeting. The tower on the right is Tokyo Tower.
