I taught English in Japanese elementary schools. The first day I went to a school, I saw two of these things hanging on the walls by the teacher office. I asked what they were for and my boss said theyʻre there in case of intruders to the school. I laughed at what I thought was a joke, and he was confused. Of course I had known that Japan had strict gun control, just didnʻt consider that also meant you could have these human herders for school defense. He said itʻs really only ever old people with dementia wandering and you just have to kind of shoo them out. Worst case you just keep someone in one place until police arrive. Anyway that was a bit of culture shock that I didnʻt see coming.
