A beloved autumn comfort dish from the Yamagata prefecture in northern Japan, this hearty taro stew is simmered with thin-sliced beef, root vegetables, and konjac in a light soy-mirin broth. It is traditionally cooked outdoors in massive pots along riverbanks during the imoni-kai festival, but is equally delicious made at home on the stovetop.

Ingredients
For the stew base
- 1.2 lb satoimo taro root (about 8 small tubers), scrubbed
- 1 sheet white konjac (konnyaku), cut into bite-sized triangles
- 1 medium burdock root (gobo), scrubbed and sliced diagonally
- 4 large dried shiitake mushrooms, rehydrated and sliced
- 6 cups dashi stock (kombu and bonito based)
For the protein and aromatics
- 12 oz thinly sliced beef (sukiyaki-style or shabu cut)
- 2 tablespoons neutral oil
- 1 large yellow onion, sliced into wedges
- 1 large burdock root, sliced on the bias into thin ovals
- 1 small piece fresh ginger (1 inch), peeled and julienned
For the seasoning and finishing
- 3 tablespoons soy sauce (usukuchi light preferred)
- 2 tablespoons mirin
- 1 tablespoon sake
- 1 teaspoon salt, or to taste
- 4 stalks Japanese leek (negi), cut into 2-inch pieces
- 1 tablespoon sansho pepper or shichimi togarashi for serving
Directions
- Bring a large pot of water to a boil and parboil the taro roots for 3 minutes until the skins loosen; drain, cool slightly, then peel off the skins with a knife and halve any large tubers.
- Heat the oil in a wide donabe or heavy Dutch oven over medium heat and sear the sliced beef in batches until just browned, then transfer to a plate.
- Add the onion and ginger to the same pot and sauté for 2 minutes until softened, then stir in the burdock and shiitake mushrooms and cook for another minute.
- Pour in the dashi stock, soy sauce, mirin, and sake, then add the konjac triangles and bring everything to a gentle boil.
- Add the peeled taro roots, reduce the heat to a low simmer, and skim any foam from the surface. Cook uncovered for 15-20 minutes, until the taro is tender when pierced and the broth has reduced slightly.
- Return the seared beef to the pot along with the negi pieces and simmer for just 2 more minutes to warm through without overcooking the meat.
- Taste and adjust with salt as needed, then ladle into deep bowls and serve piping hot with a small dish of sansho pepper or shichimi togarashi on the side.
Cook’s Notes
- Always parboil taro before simmering; raw satoimo is itchy and can irritate the mouth due to calcium oxalate.
- If true satoimo is unavailable, baby Yukon Gold potatoes are an acceptable substitute though the texture will differ.
- For a more traditional outdoor flavor, add a small piece of smoked konbu or use a charcoal-grilled cedar plank under the pot.
- Stir gently near the end of cooking to keep the taro from breaking apart and clouding the broth.
- Leftovers deepen in flavor overnight and can be reheated with a splash of fresh dashi to refresh the broth.
