This article explores the history, popularity, and regional variations of pizza in Japan. It explains how pizza was introduced in the 1950s by American servicemen, and has since become a popular snack among young people. Popular types of pizza include pan-pizza, deep-dish pizza, thin-crust pizza and traditional Italian-style pizzas. There are also several regional variations such as seafood pizzas from Hokkaido, Okinawan pizzas topped with local ingredients like goya (bitter melon) or beni shoga (red pickled ginger), and Tokyo-style pizzas featuring toppings like mayonnaise or teriyaki sauce. Fast food chains offering pizza have also had an immense impact on the local industry. The future looks bright for the Japanese pizza industry as more young people embrace western culture through food trends from overseas markets.
