Toshikoshi Soba are warm soba noodles served on New Year's Eve.
There is no set tradition for the type of soba dish that you have to serve. It can be any soba dish you want; it just matters that you eat soba noodles in some form that night for luck, and that you finish eating them by midnight.
People tend to make an effort and make their soba dish from scratch on New Year's Eve, rather than using some kind of instant soba noodle in a plastic pot dish.
"Toshikoshi" in Japanese means "year crossing."
