Hegi Soba, also searched as Niigata funori buckwheat noodles, is a regional noodle from the Uonuma area. Funori seaweed is simmered into a green paste, kneaded into buckwheat flour, cut into even noodles, and served in one-bite mounds on a flat wooden board with dipping sauce, onion, and mustard.
Ingredients
- Dried funori (seaweed binder) 30 g
- Buckwheat flour 400 g
- Water (for simmering the funori and for kneading, as needed) about 400–500 ml (adjust as you go)
- [Dipping sauce] Mentsuyu (3x concentrate) 100 ml
- [Dipping sauce] Water 200 ml
- [Condiments] Naganegi (long onion), thinly sliced, as needed
- [Condiments] Prepared Japanese mustard (neri-garashi) as needed
- [Condiments] Toasted white sesame (optional) as needed
Steps
- Rinse the dried funori lightly in water and put it in a pot. Add a little more water than needed to just cover it (enough to hide the funori, about 300–400 ml) and simmer slowly over low heat. Cook 45–60 minutes, until the mass approaches a clean green, stirring now and then so it does not scorch. A copper pot helps the color develop, but a home stainless-steel pot works if you take the time. Let
- For 400 g buckwheat flour, add enough funori paste to make about 20 percent of the total (a weight ratio of roughly 8:2 buckwheat to funori). If the dough is dry, add funori cooking liquid or water a teaspoon at a time and knead firmly with both hands until it is as soft as an earlobe. Once it comes together, wrap it and rest 15–20 minutes.
- On a board dusted with flour (buckwheat flour or starch for rolling), flatten the dough. Aim for a thickness of 2–3 mm and roll it with a pin so the edges are even. Fold it, then cut by pressing the knife downward rather than drawing it toward you, so the noodles are even in width. Dust the cut noodles and shake them apart.
- Bring a generous pot of water to a boil and scatter the noodles in. After it returns to a boil, cook over medium heat for 40–60 seconds (a little more or less depending on how the flour was milled and how thick the noodles are). Lift them into a colander before the cooking water becomes too cloudy and rinse thoroughly in cold water to remove the slipperiness. A final ice-water rinse helps the chew
- Mix the mentsuyu and water to make the dipping sauce and divide it among small bowls. Gather the noodles in one-bite bundles and arrange them on a flat dish (a hegi board is ideal if you have one), then add the onion, mustard, and sesame if you like. Do not dissolve the mustard completely into the sauce; place a little on the noodles, then dip them in the sauce to eat.

Notes
It is often said that funori's clean green develops more readily in contact with copper ions. Even without a copper pot at home, a long, low simmer still makes a very good noodle.
How much water buckwheat flour absorbs changes with the weather and the grind. Do not add the water or funori cooking liquid all at once; watch the dough as you knead. If it turns sticky, dust on more buckwheat flour.
If you do not have a hegi board at home, arranging one-bite portions on a flat wooden plate or tray in the teburi style still gives the right feel. Do not pile them high; smaller servings are easier to eat.
In Uonuma, mustard is the standard condiment rather than wasabi. Store-bought prepared mustard is fine; if it is too hot, start with a very small amount.
The aroma is especially good when the new autumn buckwheat (akishin) is in season. There is also a shortcut that adds commercial funori binder to dried 100-percent buckwheat noodles, but the flavor does not match noodles you roll yourself.

Substitutes
- Copper pot → stainless pot, long low simmer
- Hegi board → flat wooden plate or tray
- Japanese mustard → a little wasabi (mustard is more local)
- 3x mentsuyu → Kanto-style noodle sauce, diluted
- Toasted white sesame → optional, can omit
Storage
Freshly rolled and boiled noodles taste best. The funori paste keeps about 2 days in the fridge; wrap the dough and roll it within a few hours. Cooked noodles lose their chew quickly, so store them apart from the dipping sauce and eat soon. Overnight leftovers slacken, and freezing them in the sauce is not recommended.
FAQ
- How do I fix dough that is sticky or dry?
- Buckwheat hydration changes with the weather. If it is sticky, dust on more buckwheat flour and keep kneading; if it is dry, add funori cooking liquid or water a teaspoon at a time until it feels as soft as an earlobe, then rest it.
- Why do the noodles break or turn mushy?
- They were probably rolled thinner than 2–3 mm or boiled longer than about 60 seconds after the return to a boil. Use plenty of water, scatter the noodles in, and rinse off the slipperiness in cold water as soon as you lift them.
- Can I make hegi soba ahead of time?
- The funori can be simmered into a paste a day ahead and chilled. After the dough rests, roll and cut it the same day if you can; refrigerated dough should be used within a few hours. Mix the dipping sauce ahead, but boil the noodles just before eating.
- What if I have no copper pot for the green color?
- The bright green comes from a reaction with copper ions, but it is not required. A long 45–60 minute simmer in stainless steel still gives slickness and bounce, even if the paste looks a bit duller.
- How should I plate without a hegi board?
- Use a flat wooden plate or tray and set out one-bite bundles instead of a single tall pile. That makes dipping easier and is closer to the Uonuma style of serving.
Origin and history
Hegi soba is a Niigata regional noodle made with funori seaweed as the binder and served in one-bite mounds on a peeled-wood board called a hegi. It is said to have originated in the Uonuma area, when funori once used to size the weft threads of woven cloth was turned into a binder for buckwheat noodles. The funori gives a slick texture and bounce, and chopped onion with mustard is the local way to eat it.
The word hegi comes from a verb meaning to peel and refers to a square vessel. The one-bite plating is also called teburi or tebire and has a beauty related to the gestures of handling weaving threads. The noodles themselves can be enjoyed year-round, but the new buckwheat harvested in autumn is especially fine in color, taste, and aroma.
This recipe restyles 30 g dried funori and 400 g buckwheat flour into a 4-serving home version. Notes on copper-pot color and professional rolling are included as hints for approaching shop technique, while the steps themselves can be reproduced with a stainless-steel pot and an ordinary knife. With dipping sauce, mustard, and onion, enjoy a bowl that tastes of Niigata.
