Azuki Zoni is a distinctive regional variation of zoni, the traditional Japanese soup served during the New Year celebrations. Made with azuki red beans and round rice cakes, this unusual dish is especially popular in coastal areas of Tottori Prefecture, where it is an important part of local food culture.
Recipes and customs vary across the prefecture. In parts of western Tottori, both azuki zoni and clear-broth zoni are enjoyed, while clear-broth versions are more common in the mountainous areas of Hino District. Traditionally, azuki zoni was often seasoned with salt rather than sugar, and savory versions can still be found today.
Azuki zoni consists of round rice cakes served in a light broth made from gently simmered red beans. Although its appearance resembles zenzai or oshiruko, two familiar Japanese sweet red-bean dishes, azuki zoni is generally lighter and less sweet.
In some households, the New Year begins with clear-broth zoni containing rock seaweed on January 1, followed by azuki zoni from January 2. The dish is traditionally prepared with the first water drawn on New Year’s Day, known as wakamizu, which the head of the household offers to the family’s guardian deity.
Two round rice cakes are commonly placed in each bowl. Azuki beans are also associated with wishes for prosperity and the continuation of the family line because a single pod contains many beans. These customs give the dish significance beyond its role as a seasonal meal.
The neighboring Izumo region, in present-day Shimane Prefecture, has its own traditions involving red-bean zoni. During Kamiarizuki, the tenth month of the traditional lunar calendar when deities are believed to gather in the region, red-bean zoni was served during the Kamiari Festival. One theory suggests that the name zenzai originated from this ceremonial food, known as jinzaimochi. This proposed connection reflects the long-standing relationship between red-bean dishes, religious customs, and regional food traditions in the San’in area.
To make azuki zoni, red beans are simmered slowly in plenty of water over low heat. Sugar is added once the beans begin to soften, and the sweetness is adjusted to taste. A small amount of salt may be added to balance the flavor, while some family recipes include dashi stock.
The beans are generally cooked gently so that they retain their shape, creating a light, soupy consistency rather than a thick paste. Depending on household preferences, the dish may also be seasoned with miso or soy sauce. The round rice cakes are often boiled separately before serving so that they remain tender without becoming excessively soft.
Azuki zoni offers visitors a glimpse into the regional traditions that make Japanese New Year cuisine so diverse. If you visit Tottori during the winter holiday season, this distinctive red-bean and rice-cake soup is a wonderful way to discover a local dish shaped by family customs, seasonal ingredients, and generations of tradition.
