Imoni — Yamagata, Japan

Imoni is a stew made with satoimo, the Japanese taro, plus meat, konnyaku and thick scallion. In inland Yamagata the most common version uses beef and a broth seasoned with shoyu and sugar. In the Shonai region, by the Sea of Japan, it includes pork, fried tofu and miso. There are also versions with mushrooms and mountain greens, or with tofu.

According to the Ministry of Agriculture of Japan, the origin is told like this: in the 17th century, boatmen going upriver on the Mogami waited days for the people who received the cargo, near present-day Nakayama. To pass the time they cooked the taro from a nearby village on the riverbank together with the dried cod they carried. Beef only entered the dish in the early 20th century.

Imoni is the focus of imonikai, the autumn gatherings where families, friends and coworkers bring pots and ingredients to cook on riverbanks. In Yamagata, imonikai are one of the year’s major events, like New Year and year-end festivals, and during the season shops and supermarkets sell ingredients and rent pots and firewood.

In mid-September the city of Yamagata holds an imoni festival on the riverbank featuring a pot about 6.5 meters in diameter, stirred by an excavator. When the stew is finished, many people add udon or curry to the remaining broth.
