Huh?

I went to HIS travel agency to purchase flights to Tokyo for our family vacation this summer. Awesome huh?! Never in my wildest dreams did I think I would be in Tokyo on vacation. Too bad the kids will hardly remember it. Anyway, HIS has great deals on airfare and have an English-speaking staff. Unfortunately the parking meter wasn't English-speaking. Click on the picture to enlarge it and you'll see why I was so confused. It clearly says that a receipt doesn't come out. I put in 200 Yen and nothing changed on the screen. Then a little receipt popped out. I had no clue how anyone would know I had fed the meter and parking tickets are huge here so I tucked the little ticket under my windshield wiper as proof of payment. Luckily, my van wasn't ticketed or towed and I'll try to avoid Japanese parking meters in the future.
