Miscellany No. 7
Another (admittedly mundane) area of Japanese technical advancement is the umbrella. Umbrellas in Japan are mostly clear, allowing a lot less bumping into one another on the streets. And lots of bikes have umbrella holders, which seems smart providing there’s no wind. Also, Japanese museums have umbrella stands outside, with individual locks to hold your umbrella safely (although since Japan has the lowest crime rates in the world, it’s not clear why you’d worry).
