The Special Oshogatsu (New Year's) soup is ozoni.  Ingredients vary by region; there may be shiitake (mushroom), chicken, carrot, kamaboko (fishcake), daikon (radish), all cooked in dashi (fish broth).  Mochi (steamed sweet rice), which symbolizes strength, good health, and wealth, is almost always included.

The congregation is invited to observe Oshogatsu (New Year's) with a small bowl of ozoni.
