I went to Tokyo Women's Medical University Hospital in Shinjuku on the 21st of February.
I observed how the mask is being worn these days.
About 70% of the people on the train were wearing masks.
The number was about 60% in Shinjuku.
No westerners were wearing masks.
About ten Asian tourists (presumably Chinese) all wore the same blue masks.
In the hospital about 99% of the people wore masks.
It was so strange to see that many people wearing masks.
That’s it.
