Japanese people often arrange foreign style foods into Japanese favorite style. If you first come to Japan, I'm sure you will easily find so many Japanized Western Foods.
For example, Japanese curry dish is apparently imported from Indian Curry Dish, correctly it came by way of UK, and it's already Japanese Curry with different taste and different cooking stuff. But some foreign people like Japanese curry too. I love both Japanese curry and Indian curry, though. Like that, we have so many Japanized imported foods.
Today, my wife and I went to such a Western food restaurant and we had pasta and humberg steak plate. To be honest, we love both dish. But maybe Italian people and German people would not agree that these are real spagetti and humberg steak because the taste is different. Pasta looks a little similar to real dish of Italy as the photo with rightly boiled pasta and beautiful tomato sauce. But humberg steak is totally Japanese style with ginger soysauce taste. Now we find soy sauce at many steak restaurants in USA because soysauce goes well with meat dish, so you might think this humberg steak could taste OK. Yes, its taste is really good ( at least for me ).
Not only these two things, but there also are many Japanese flavored food by idea of Western food. I will try to introduce more.
