If you love Japanese food, you must heard of it once. FYI, Sukiyaki is one of Nabemono type and it is a cold weather food. People in Hokkaido usually eat this at home with their family or co-workers.
Nabemono (鍋物, なべ物) nabe "cooking pot" + mono "thing or things, object, matter" or simply called nabe, refers to a variety of Japanese hot pot dishes, also known as one pot dishes.
