winter food in Japan

Some friends came to my flat in the evening,and we had dinner together.I cooked 'Nabe' which is like a stew,and is a very popular winter food in Japan. I prepared a soup in a big pan,and then put chicken,tofu,and a lot of vegetables(chinese leaf,greens,carrot,leek,mushroom,radish,etc... ) into the pan,and simmer. When they are done,dip it in a sauce made by soy sauce + sesame sauce. We enjoyed it very much.
