Shakey's Pizza is inexplicably popular in Japan. Well, that's not quite true. There's an explanation, but it doesn't really make a lot of sense in a country of relatively affluent people with ready access to good quality food. They are mainly popular for their incredibly crappy lunch buffet which is a festival of bad carbohydrates (fried potatoes, sparsely topped pizza, and spaghetti).
The good folks at Shakey's have taken the cake when it comes to "weird" Japanese pizza. The specimen at the bottom has pumpkin, red bean paste, mini marshmallows and black sesame sauce. The marshmallows really are the kicker. This is a culture that reacts with abhorrence at the idea of candied sweet potatoes so my husband and I did a double-take when we saw this sign. Yes, they've finally become "one of us".
