One of the experiences that happened casually that added color and humor to my days in Japan was finding places with misspelled words that carried unintended meaning. I have to say that life in America seems a lot "flatter" due to not running across such innocent signs and messages. In Japan, my husband and I would be walking along and he'd says, "look at that" and point out something funny and we'd both smile. In America, if we're walking along and he says, "look at that," there's a good chance that it's something awful, scary, or painfully inappropriate or stupid like a guy jogging on a heavily trafficked road with his dog and the dog is not on a leash. It's far more likely that we'll be cringing than smiling at random encounters.
I continue to miss the humor and innocent charm of those misspellings we not infrequently encountered in Tokyo.
