Where's the pepperoni?

Let's think international today! Did you know that pizza is also popular in Japan? It's NOT all about sushi, it seems.
Here is a list of the most popular toppings for pizza in Japan:

1. Bacon
2. Seafood
3. Onion
4. Corn
5. Salami
6. Tuna
7. Mushrooms
8. Ham
9. Potato
10. Green pepper

Hmmm. It makes me wonder what other countries like to put on pizza. Anybody want to do a report? Or wait--what a great question to ask the reference librarian!
