I saw a misspelling this morning. Nothing unusual about that, except that this one was in Japanese! It is hard, but possible to misspell a few words in Japanese, and someone had managed it, in metre-high lettering across a bridge. It was some official banner exhorting drivers to take care and drive safely.
I checked with a few Japanese people and they all agreed with me, that it was an embarrassing mistake. I felt quite pleased with myself for noticing it! I’ll take my camera and photograph it when I pass the same place next week.
