According to the link below:
" Actually probably the most common Pizza topping in Japan is sweet corn. I'm not sure why none of these pizzas have it, perhaps Pizza Studio was trying to get away from the "usual." It's weird at first but it's really not bad if you like veggies. Also not pictured but not unusual in Japan are pizzas with a potato/mayonnaise theme (often called The Idaho Special ). Another common pizza topping here which I can't find in my hometown pizza parlors are slices of boiled egg."

Cheese! I worked at Pizza Hut and the most ordered topping was cheese. More extra cheese and cheese pizzas went out than anything else (Yes, even more than pepperoni). So that would be the most popular.
