Too windy for an umbrella

This is the debris after strong wind blew this area (Tokyo).
I clearly remember that I asked my friend why you don't use an umbrella there in stead of wearing rain-jacket when I was in UK.
At that time, I thought people in UK would NOT like them.
His answer was very clear. "too windy to use it here."

Although this type of umbrellas are very cheap to use under very bad condition (windy) in Tokyo, many people seemed to have been uneasy to use them on that day here.
