Oddness. Please elaborate!

some highlights from that site:
Some of the weirder things that you can get on a pizza in Japan are mayonnaise
broccoli
corn
shrimp
squid
zucchini
squash
boiled eggs
tuna
octopus
potatoes
eel
Broccoli is rather common these days (in gourmet establishments), and I used to think corn was a crazy topping until I had one with such at California Pizza Kitchen. Later I proceeded to make my own corn pizza variety. I believe I chronicled that with pictures at one point, as well. Turned out rather good.
Pizza Hut Japan
The Japanese arm of the Pepsico owned Giant. Since KFC is a national staple in Japan it is no surprise that Pizza Hut would show up in Japan. Check out the Korean Purokogi style Pizza. Kim-chee on pizza... it is so crazy that is might work. I love their Idaho Special pizza is covered in Potatoes when absolutely noone in the US state of Idaho puts potatoes on their pizza.
KIMCHEE?! winnar.
And looking over that Pizza Hut Japan menu, I notice a few mayo choices.
