Sukiyaki is a Japanese dish that is prepared and served in the nabemono (Japanese hot pot) style.

It consists of meat (usually thinly sliced beef) which is slowly cooked or simmered at the table, alongside vegetables, in a shallow iron pot in a mixture of soy sauce, sugar, and mirin.

The ingredients are usually dipped in a small bowl of raw, beaten eggs after being cooked in the pot, and then eaten.

Generally sukiyaki is a winter dish and it is commonly found at bōnenkai, Japanese year-end parties.

Sukiyaki is a one pot dish that was developed during the Meiji era. Different regions have different ways of preparing sukiyaki. There are two main styles, the Kanto style from eastern Japan and Kansai style from western Japan.

In the Kanto style, warishita (a mixture of sake, soy sauce, sugar, mirin and dashi) is poured and heated in a pot, then meat, vegetables and other ingredients are added and simmered together.

In Kansai-style sukiyaki, meat is heated in the pot first. When the meat is almost cooked, sugar, sake and soy sauce are added, then vegetables and other ingredients are added last.

The vegetables and meat used are different between the two styles. Because beef was expensive in the past, the use of pork was common in northern and eastern regions.

Other ingredients added to modern sukiyaki include chicken (tori-suki), fish (uo-suki), udon noodles (udon-suki), negi, shiitake mushrooms, shirataki and slightly grilled tofu.
