The standard Japanese food consists of a carbohydrate like rice or a noodle, a serving of miso soup, as well as a dish of pickled vegetables, and, optionally, a meat or a fish dish. The most common carbohydrate is rice, but many different types of noodles are available, including udon (thick noodles), soba (medium noodles), and ramen (thin noodles). These carbohydrates are all very inexpensive and form the main backbone of the dish. Additionally, fish dishes are very popular parts of meals, because Japan has a long history of fishing and eating different seafoods like many island nations. These seafoods can include many different species of sea creature, such as a huge number of types of fish as well as squid, octopus, shellfish like oysters and mussels, and even eels.
