Kiriboshi Daikon — Japanese Simmered Dried Daikon Radish
Kiriboshi daikon (切り干し大根) is daikon radish that’s been shredded and dried in the winter sun until it’s brittle and amber-colored. Drying concentrates it — the sweetness, the minerals, and a faint smokiness that fresh daikon doesn’t have at all. Simmered with carrot and fried tofu in a soy-dashi broth, it becomes one of the most ordinary, most everyday side dishes in Japanese home cooking.
This is genuinely humble food. A bag of dried daikon costs almost nothing, keeps in the cupboard for months, and turns into four servings of vegetable side dish in about twenty minutes. It’s the kind of thing that appears in a small bowl next to rice, in a bento, or in the plastic deli containers at a Japanese supermarket — and almost nobody outside Japan has heard of it.

Why You’ll Love This Recipe
- It comes out of the cupboard. Dried daikon keeps for months, so this is a vegetable side dish you can make with nothing fresh in the fridge except a carrot.
- Better on day two. It’s meant to be made ahead — the flavor keeps soaking in as it sits.
- One pan, twenty minutes. Most of that is the daikon soaking while you do something else.
- Cheap, filling, and full of fiber. Drying concentrates the nutrients along with the flavor.
What is Kiriboshi Daikon?
Kiriboshi (切り干し) means “cut and dried,” and daikon (大根) is the long white Japanese radish. Fresh daikon is about 95% water, mild and slightly peppery. Take that water away in the cold winter wind and you get something completely different: chewy, distinctly sweet, and concentrated enough that 30 grams of it feeds two people.
It’s a preservation method from before refrigeration, and it survived because the dried version genuinely tastes better in this dish than fresh daikon would. You’ll also see it labeled sengiri daikon (せんぎり大根, “shredded daikon”) — the bag I buy uses that name. Same thing, different region’s word for it.
The bag in the photo is from Miyazaki, on the other side of Kyushu from me — the label makes a point of saying it was dried in the cold winter wind rather than in a machine, which is what gives it the sweetness. Miyazaki and neighboring Kagoshima produce most of Japan’s kiriboshi daikon, for the practical reason that the winters there are dry and windy.
Where to Buy Kiriboshi Daikon
Any Japanese or Korean grocery store will have it, usually in the dried goods aisle near the dried shiitake and kombu, in a clear bag of what looks like pale brown straw. It’s one of the cheapest things in the shop. Online it’s sold as “kiriboshi daikon,” “dried daikon,” or “dried radish strips” — all the same product, so search whichever name your shop uses.
If you don’t have a Japanese grocery within reach, Eden finely shredded dried daikon radish on Amazon is the easiest way to get it — it’s traditionally dried rather than machine-dried, which is the distinction that matters for sweetness, and one bag makes this dish several times over.
Two things to check when you buy: the color should be pale cream to light tan, not dark brown (dark means it’s old and will taste bitter), and it should smell faintly sweet rather than musty. Once opened, keep the bag sealed in a cool cupboard and use it within a couple of months.
Ingredients (Serves 2)
| Ingredient | Amount | Notes |
|---|---|---|
| Kiriboshi daikon (dried daikon) | 30 g / about 1 oz | Dry weight — it triples when soaked |
| Carrot | 1 (about 150 g) | Cut into matchsticks |
| Aburaage (fried tofu) | 1 sheet | Cut into thin strips |
| Water | 300 ml | |
| Dashi powder | 2 tsp | Granulated |
| Soy sauce | 2 tbsp | |
| Sugar | 2 tsp | |
| Mirin | 2 tsp | Hon-mirin |
| Neutral oil | 1 tbsp | For frying |
The broth is four pantry things: dashi powder, Japanese soy sauce, sugar, and hon-mirin. That’s the standard Japanese simmering base, and if you have those you can cook half the vegetable side dishes in the country — they’re all on my list of Japanese pantry essentials.
Aburaage is thin deep-fried tofu, sold refrigerated or frozen at Japanese groceries. It soaks up the broth like a sponge and is the thing that makes this taste finished rather than thin. If you genuinely can’t find it, leave it out rather than substituting — the dish still works, it’s just less rich. I use the same ingredient in sweet simmered tofu pouches.
How to Make Kiriboshi Daikon
Step 1: Soak the Dried Daikon
Rinse the dried daikon quickly under running water, then put it in a bowl and cover it with cold water. Leave it for about 15 minutes. It swells to roughly three times its dry volume, so use a bigger bowl than you think you need — 30 grams looks like almost nothing in the bag and fills a whole bowl once it’s rehydrated.
The soaking water turns a clear amber, which is the sugars coming out of the daikon.
Step 2: Squeeze It Dry
Drain the daikon and squeeze it firmly with both hands to get the water out. Squeeze harder than feels polite — any water left in it dilutes the broth and the dish ends up watery instead of concentrated. If the strands are very long, cut them into shorter, chopstick-friendly lengths.
Step 3: Cut the Carrot and Aburaage
Peel the carrot and cut it into matchsticks about the same thickness as the daikon strands, so everything cooks at the same rate and picks up together with chopsticks. Cut the aburaage into thin strips of similar length.
Step 4: Stir-Fry Everything in Oil
Heat the oil in a frying pan over medium heat and add the daikon, carrot, and aburaage together. Stir-fry until the carrot softens and loses its raw edge, two or three minutes. Don’t skip this step and go straight to simmering — coating everything in oil first keeps the daikon from going mushy and gives the finished dish a rounder flavor.
Step 5: Add the Broth and Simmer
Add the water, dashi powder, soy sauce, sugar, and mirin. Bring it to a simmer over medium heat and let it cook uncovered, stirring now and then, until the liquid has reduced to about a third of what you started with. This takes roughly 10 to 15 minutes.
Stirring occasionally matters more than it sounds — it’s what moves the seasoning through evenly as the liquid concentrates.
Step 6: Take It Off While There’s Still a Little Liquid
Stop when there’s a small amount of glossy broth left pooling in the pan rather than cooking it completely dry. The daikon keeps absorbing as it cools, so a pan that looks slightly wet now will be perfect by the time it reaches the bowl. Cooked until bone dry, it turns tough.
Tips and Variations
- Keep the soaking water. It’s sweet and full of flavor, and plenty of Japanese cooks use it in place of some of the water in the broth. Strain it first, and taste — if your daikon was old, the water can be slightly bitter, in which case throw it out.
- Don’t over-soak. Fifteen minutes is enough. An hour makes it limp and washes out the sweetness you’re paying for.
- Squeeze harder. The single most common reason this dish comes out bland and watery.
- Add dried shiitake. Soak two or three alongside the daikon, slice them, and add them in with the carrot. They belong in this dish.
- Add chikuwa or a little pork. Both are common home additions if you want it more substantial.
- Make it vegan. Swap the dashi powder for kombu or dried shiitake stock — see my guide to dashi substitutes. Aburaage is already plant-based.
What to Serve It With
This is a kobachi — a small-bowl side dish. It never sits in the middle of the table; it sits beside the rice.
- Rice, miso soup, and a grilled fish — the standard Japanese dinner, and where this belongs.
- Alongside a richer main like ginger pork, where its plainness is the point.
- Cold, straight from the container, in a bento box. This is probably how most of it actually gets eaten.
Storing
Kiriboshi daikon keeps in an airtight container in the fridge for four or five days, and it is genuinely better on the second day — the broth finishes soaking in overnight. Eat it cold, at room temperature, or briefly reheated; all three are normal, and cold straight from the fridge is the most common.
It freezes well too, which is why people make a big batch. Portion it into small containers and freeze for up to a month — it thaws in a bento box by lunchtime, which is exactly what it’s used for.
Frequently Asked Questions
What is kiriboshi daikon?
Daikon radish shredded and dried in the sun until brittle. Drying removes the water and concentrates the sugars, so it tastes sweeter and chewier than fresh daikon, with a faint smoky note. It’s sold dry in bags and rehydrates in about 15 minutes. It’s also labeled sengiri daikon, dried daikon, or dried radish strips.
How long do you soak dried daikon?
About 15 minutes in cold water — long enough for it to swell to roughly three times its volume and turn soft but still chewy. Longer isn’t better: over-soaking makes it limp and leaches out the sweetness. Squeeze it firmly afterward.
Can you use the soaking water?
Yes, and many Japanese cooks do — it’s sweet and carries flavor, so it can replace part of the water in the broth. Strain it and taste it first. If the daikon was old, the water can be bitter, and then it’s better thrown away.
What does kiriboshi daikon taste like?
Sweet and mellow, with a chewy, slightly fibrous texture — closer to a dried mushroom than to fresh radish. The sharp peppery bite of raw daikon is completely gone. Simmered in soy and dashi it tastes savory-sweet and mild, which is why it works as a background dish next to rice.
Is kiriboshi daikon healthy?
It’s very high in fiber, and drying concentrates minerals like calcium and iron relative to fresh daikon. The dish itself is low in fat — the only additions are a tablespoon of oil and a couple of teaspoons of sugar across two servings. The soy sauce makes it salty, so that’s the one thing to keep an eye on.
Can I make it without aburaage?
Yes. The dish is still good, just lighter — the fried tofu is what soaks up the broth and adds richness. Don’t substitute plain tofu, which falls apart and adds water. Thinly sliced pork or chikuwa fish cake are the usual alternatives if you want something in that role.
Can I use fresh daikon instead?
You can simmer fresh daikon the same way, but it’s a different dish — milder, softer, and without the sweetness or the chew. Fresh daikon also releases a lot of water into the pan, so you’d need less liquid. For this recipe the dried version isn’t a substitute for fresh; it’s the point.
Kiriboshi Daikon (Japanese Simmered Dried Daikon Radish)
Ingredients
Method
- Rinse the dried daikon briefly, then cover it with cold water in a large bowl and soak for about 15 minutes, until it swells to roughly three times its volume and turns soft but still chewy.
- Drain and squeeze the daikon firmly with both hands to remove as much water as possible. Any water left behind will dilute the broth. Cut very long strands into shorter lengths.
- Peel the carrot and cut it into matchsticks about the same thickness as the daikon strands. Cut the aburaage into thin strips.
- Heat the oil in a frying pan over medium heat. Add the daikon, carrot, and aburaage together and stir-fry for 2 to 3 minutes, until the carrot softens. Do not skip this – coating everything in oil keeps the daikon from going mushy.
- Add the water, dashi powder, soy sauce, sugar, and mirin. Bring to a simmer over medium heat and cook uncovered, stirring occasionally, for 10 to 15 minutes, until the liquid has reduced to about a third.
- Take the pan off the heat while a little glossy broth still pools in the pan – the daikon keeps absorbing as it cools. Serve warm, at room temperature, or cold.
