It is not happy to experience sudden rain when you do not have an umbrella.
Especially when you are wearing suits or nice clothes and get off train and see raining, you just sigh.
But there are goodwill umbrellas in some station in Japan.
The goodwill umbrellas are placed in a corner of a station and anyone can use them.
After using them, you can just return them to same place and some other people use it when they need.
