Tis the rainy season in Japan right now meaning that many house and shop entrances across Japan start to fill up with transparent umbrellas.
And why transparent umbrellas? Mainly because most of them cost 100 yen and can usually be picked up from a convenience store. Folks caught out in the rain would go and pick one up for temporary use and leave it for others to use later. They are quite durable and can last a long time as long as you don't stick it up your bottom.
