The "Imoni" (stewed potato stew) party is loved by local people as a typical autumn event, especially in the Tohoku region. As the name implies, Japan's No. 1 Imoniikai Festival, held every September in Yamagata City, Yamagata Prefecture, is the largest in Japan in terms of the scale of the event! In this issue, we will introduce the schedule, events, and things to do at Japan's No.1 Imoniikai Festival 2025.

Speaking of autumn in Yamagata, a taro stew party is held on a riverbank.

Everyone knows that the soul food of Yamagata Prefecture is "imoni" (stewed potatoes). In autumn, it is a regular event for people in Yamagata Prefecture to get together with family, relatives, friends, or company social gatherings and have a taro stew party at a riverbank. Some supermarkets offer free rental of a set of tools for a taro stew party during the taro stew party season, and the culture of this event is deeply rooted in the community. The "Japan's No. 1 Imojikai Festival," the parent of the Imojikai, is scheduled to be held on Sunday, September 14, 2025. We hope you will come to this dynamic potato stew festival, which is worthy of the name "Japan's No.1!

Yamagata's Imoni Festival actually holds a Guinness record!

Japan's No.1 Imojikai Festival started in 1989, and the 30th festival in 2018 was recognized by the Guinness Book of Records as the "Most Soup Served in 8 Hours," to our surprise. In 2022, the festival will be recognized by the Agency for Cultural Affairs as one of the "100 Years of Traditional Foods". In 2022, the festival was recognized by the Agency for Cultural Affairs in the "Traditional 100-Year Food Category: Local Cuisine Continuing from the Edo Period" and received a special award from the Agency for Cultural Affairs.
Enjoy the delicious taro stew!

Everything is dynamic! A scale that is out of the standard!

The pot used at Japan's No.1 Imoni Festival is a giant pot with a diameter of 6.5 meters. It is nicknamed "Nabetaro," and the pot currently in use is the third generation Nabetaro. This giant Nabetaro cooks approximately 30,000 meals at once. The cooking method is also dynamic, and heavy equipment, a "mobile crane specification machine/backhoe," is used, and sanitation is strictly controlled. Before the potato stew, the parts are disassembled into small pieces and thoroughly cleaned, and butter is used as lubricant. It is said that about 100 servings of taro stew can be scooped using this special backhoe, and it supports the largest taro stew festival in Japan, which is attended by many people every year.
