Osechi is a traditional Japanese New Year dish, typically prepared in advance and enjoyed during the first three days of January. It consists of various colorful foods, each symbolizing good fortune, health, and prosperity for the coming year. The dishes are often arranged in special boxes called jubako, which resemble bento boxes. Common ingredients in osechi include kuromame (sweet black soybeans for health), kazunoko (herring roe for fertility), and tazukuri (candied sardines for a good harvest). Families often share osechi together, making it a festive and meaningful part of New Year celebrations in Japan.
