No matter how long a person lives in Japan, there are always things that can bring on what expats call a "Japan moment," the feeling of utter amazement at something bizarre you've just encountered. Maybe it's something cute, like a big truck playing the Main Street Electrical Street Parade song as it backs up instead of a boring beep-beep-beep sound, or that first time seeing the plastic Colonel Sanders in front of KFC wearing his "Santa Wear" (Santa Claus Suit). Maybe it's a food item, like strawberry and whipped cream sandwiches, or the ham and cheese on French Toast complete with syrup pre-applied to the bread I saw once. You never know what will bring on that sense of "only-in-Japan" next -- driving through an extremely rural town and coming across a replica of the American Statue of Liberty? Seeing a nondescript building with "Oh!" carefully painted on it? Meeting someone who has taught English for 30 years yet has never been outside of Japan, and who asks you "Where is your domicile?" instead of something simple like "Where do you live?"
Great placement on that door, guys.
