Zoni, also known as Ozoni, is a comforting soup traditionally served in Japan during the New Year celebration. Made with mochi (rice cakes) and a variety of regional ingredients, this dish holds deep cultural significance and represents good fortune and renewal. In this article, we explore what Zoni is, its history from ancient to modern times, regional styles, and how to prepare it at home—whether you’re honoring tradition or discovering Japanese cuisine for the first time.
What is Zoni? A Traditional Japanese New Year’s Soup
Zoni, also called Ozoni, is a traditional Japanese soup featuring mochi (glutinous rice cakes) that is customarily eaten during Oshogatsu, the Japanese New Year celebration. It is more than just a seasonal delicacy—it embodies deep-rooted cultural values and spiritual meaning. At its core, Zoni consists of mochi simmered in a flavorful broth alongside various vegetables and proteins. However, the exact ingredients and preparation methods differ significantly across regions and even households, showcasing Japan’s culinary diversity.
The term “Zoni” is believed to originate from the verb ni-zoru, meaning “to cook together.” This reflects the communal nature of the dish, as families gather to prepare and eat it at the start of a new year. In essence, Zoni symbolizes unity, gratitude, and a hopeful beginning. It is often included in the Osechi Ryori, a set of traditional New Year’s dishes, and is served on January 1st as the first meal of the year—a gesture believed to bring good fortune and health.
The History of Zoni: From Court Cuisine to New Year’s Tradition
Zoni has a long and storied history that dates back to Japan’s Heian period (794–1185), where it was served as part of yusoku ryori (imperial court cuisine) during ceremonial occasions. At that time, it was associated with formality and spiritual rituals. The dish evolved during the Muromachi period (1336–1573), becoming popular at samurai banquets. Warriors would consume it before battle for strength and luck.
By the Edo period (1603–1868), Zoni had spread to the general population and became firmly rooted as a New Year’s tradition across Japan. Over time, each region developed its own take on the dish based on local ingredients and preferences, forming the basis of today’s diverse Zoni styles.
Development of Zoni
| Period | Role of Zoni |
| Heian (794–1185) | Served in imperial ceremonies |
| Muromachi (1336–1573) | Prepared at samurai feasts and gatherings |
| Edo (1603–1868) | Spread to commoners as a New Year custom |

Cultural Significance of Zoni in Japanese New Year Traditions
In Japan, the New Year is more than a celebration—it’s a time of spiritual renewal. Zoni plays a pivotal role in this ritual. As part of Osechi Ryori, it is the centerpiece dish served on New Year’s morning, symbolizing a fresh start and blessings for the coming year.
Mochi, the star ingredient in Zoni, is imbued with symbolic power. It represents strength, resilience, and long life—qualities desirable for a new year. Many of the vegetables and garnishes included in the soup are chosen for their auspicious meanings: carrots and daikon represent fertility and vitality; leafy greens symbolize growth and prosperity. Eating Zoni is also considered a way to honor the Toshigami, the deity of the New Year, who is believed to visit homes during this time.
Through this meal, Japanese families express gratitude for the past and hope for the future, all while participating in a tradition that links generations.
Regional Variations: Kanto vs. Kansai and Beyond
Zoni is perhaps most fascinating for its regional diversity, offering a culinary map of Japan in a single bowl. Two of the most well-known styles come from the Kanto and Kansai regions.
- Kanto-style Zoni, common in Tokyo and the eastern parts of Japan, features a clear, soy sauce-based broth with grilled square mochi. The soup typically includes chicken, kamaboko (fish cake), leafy greens like spinach, and carrots.
- Kansai-style Zoni, found in areas like Kyoto and Osaka, uses a white miso broth with round, boiled mochi. The broth is creamier and slightly sweeter, often featuring daikon, carrot, and taro root.
Kyoto-style Zoni goes a step further with the use of sweet white miso and unique additions like yuzu peel and tofu, adding a fragrant, citrusy note.

These versions preserve the symbolic and communal essence of Zoni while offering new flavor experiences.
Zoni Around the World: How the Diaspora Keeps the Tradition Alive
Japanese diaspora communities have found creative ways to preserve the Zoni tradition while adapting it to local ingredients. In places like California, Hawaii, and Brazil, families prepare Zoni with regional twists—using napa cabbage instead of mitsuba, or yucca in place of taro.
Consider a Japanese-American family in Los Angeles, who prepare Kanto-style Zoni with free-range chicken and kale. Or a Brazilian-Japanese family in São Paulo, who combine local root vegetables with mochi imported during the holiday season. These adaptations reflect a deep emotional connection to heritage and an enduring respect for tradition.
Zoni thus becomes more than a meal—it’s a way for the Japanese diaspora to pass on identity, memory, and meaning to new generations.
