Well, I’ve gone and done it. I’ve started a nukadoko.

When I first got interested in nukadoko pickles, the first thing I thought about was where to get the rice bran.

Starting by Choosing Reliable Rice Bran

Rice bran is sold at supermarkets and department stores. But something nagged at me.

The pesticides and chemical fertilizers used in growing the rice, and the additives that might come in during processing. If I was starting nukadoko for my health, it felt a bit off to include all of that.

So I reached out to a miso shop in Fukui Prefecture, in business since 1914, that I’d come to rely on. They wrote back with a thorough reply, letting me know they also carry trustworthy rice bran. I ordered without hesitation.

Miso and rice bran, both from the same shop in Fukui. The idea of sourcing what I put in my body from a place I can trust has taken root in me naturally.

I Was Particular About the Container Too

I went to a home improvement store to find the right container.

Nukadoko is high in salt. I needed something sturdy, made of a material that wouldn’t be degraded by salt. I picked up several options in person and chose the right size for nurturing a nukadoko bed.

Nurturing the Nukadoko with Scraps, Kombu, and Chili

I put the rice bran in the container, added salt, and mixed. Then I added dried chili peppers and kombu kelp.

The chili is for preservation and flavor. The kombu draws out umami. Both have been used in traditional nukadoko-making for generations.

Then there’s the “scraps” — another key component.

Scraps means the parts of vegetables we’d normally throw away: carrot peels, daikon radish leaves, cabbage outer leaves. These get buried in the nukadoko for about a week to encourage fermentation. You don’t pickle vegetables for eating right away — first you need a period to let the nukadoko bed develop.

After a week, I gently turned the bran. A wave of fermentation aroma rose up. That was the moment I thought, “It’s alive.”

The Nukadoko’s Home Changes with the Seasons

Temperature management is crucial for a nukadoko.

In summer, when it’s hot and fermentation moves too fast, the nukadoko goes in the refrigerator. In winter, when fermentation slows down, I keep it in the entryway — the coolest spot in the house.

Everyone says “you have to mix it every day” — but I’ve learned that when it’s in the fridge, you don’t have to be quite so strict about it. I watch the condition of the nukadoko and engage with it at my own pace.

Mixing by Hand Changes Your Hands

You mix a nukadoko with your bare hands.

At first that felt a little off-putting, but once you get used to it, it’s actually pleasant. You start to get a sense of the bed’s condition just from the temperature and texture.

And there’s something else I noticed: my hands started looking better.

Rice bran is rich in vitamin E and ferulic acid — nutrients that are good for skin. Mixing it every day, the roughness I used to have on my hands gradually stopped bothering me. The nukadoko wasn’t just nurturing the vegetables — it was nurturing my hands too.
