Kirk here with a little report on a multilayered instance of “lost in translation.” I laughed when I noticed the English on this sign because I could see immediately that the Japanese was referring to the danger of PEOPLE falling from the window but the translation (probably from DeepL or some other machine translation service) makes it sound like the danger is that the window may fall. I guess the editor of the popular Facebook group about English mistakes who rejected my post understands Japanese about as well as DeepL.
