While kaitenzushi is my favorite healthy Japanese fast food, tonkatsu is my favorite unhealthy Japanese food. Tonkatsu is a deep fried pork cutlet. The picture shows a nice tonkatsu set with shredded cabbage on the side (it also comes with soup and rice). Before eating you can dip it in tonkatsu sauce – a sweet heavy sauce that I am sure is also very unhealthy. You can find lots of restaurants in Japan serving only tonkatsu. If you’re ever in Japan I recommend trying one.
