Yamagata Imoni Festival

Yamagata’s autumn comfort food is imoni — a hearty stew of taro, beef, konnyaku, and green onion in a sweet-soy broth — and every September the whole region celebrates it in the most over-the-top way imaginable.

Why It’s Interesting

At the Nihon-ichi no Imoni-kai (“Japan’s No.1 Imoni Gathering”), a single colossal cauldron — roughly six metres across — is set up on the Mamigasaki riverbed, filled with tonnes of ingredients, and stirred not by ladles but by a construction crane fitted with a giant scoop. Over the day it cooks around 30,000 bowls of stew, ladled out to the crowds who pour in from across the city to share one enormous communal meal. It’s part festival, part civic record-attempt, part outdoor potluck — and gloriously, quintessentially Roadside Japan.

Best Time to Visit

A Sunday in mid-September (usually the third Sunday) — a little after a peak-summer trip, but worth knowing about. Go early, before the bowls run out.

Getting There

The Mamigasaki riverbed is a walk or short bus from Yamagata Station; come by transit, as the area is mobbed.
