While udon and soba are also believed to have come from China, only ramen retains its image as Chinese food. Ramen is thin egg noodles which are almost always served in a hot broth flavored with shoyu or miso. This is topped with a variety of ingredients such as slices of roast pork (chashu), bean sprouts (moyashi), sweetcorn and butter. Ramen is popular throughout Japan and different regions are known for their variations on the theme. Examples are Corn-butter Ramen in Sapporo and Tonkotsu Ramen in Kyushu. Instant ramen (the most famous brand is Pot Noodles), to which you just add hot water, has become very popular in recent years
