This is a asaoke—a shallow-style pickling tub.
It has a lower height than standard pickling tubs, making it especially well suited for nukazuke (rice bran pickling).

Pickling containers are available in a variety of materials, including plastic and enamel, but this one is crafted from natural wood: sawara.

This product uses Kiso sawara, a type of sawara cypress grown in the Kiso region of Nagano.

The standing trees resemble hinoki in appearance, but the wood is softer, lighter, more water-resistant, and easier to work with than hinoki.

Sawara gently absorbs moisture and has a more subdued scent compared to hinoki.
Its mild character makes it well suited for use with food, and it has long been favored for items like rice tubs, wooden rice containers, and drop lids.

We introduce a shallow tub fitted with a bamboo hoop, known as a “taga”, which is placed around the body of the tub.

It is available in two sizes: 27cm and 30cm in diameter (approx. 10.63″ to 11.81″).

Let us introduce each size.

※ Before using the tub, please begin with the initial soaking process to remove bitterness and odor.

We recommend a simple preparation step to help condition the wood.
Fill the tub about 80% full with rice-washing water (the water from rinsing rice),
and let it sit for 3 to 8 hours.
Since some water may seep out, it’s best to do this in a sink.
This process allows the wood to swell slightly and may help seal minor gaps.
It also helps soften the scent of the sawara cypress using the natural deodorizing effect of the rice water.

Wooden tubs for nukazuke and pickling are becoming less common these days.

But the flavor of pickles touched by the scent of sawara is truly special.
The wood also helps regulate moisture, so excess water rarely collects in the nukadoko.

Of course, daily care is still essential,
but once you get used to how sawara behaves,
many find it easier to manage than enamel or ceramic containers.

From summer vegetables like cucumbers and eggplants
to cool-weather favorites like daikon and carrots,
nukazuke can be enjoyed year-round as a perfect companion to rice.

These tubs may not feel as familiar now,
but something about the presence of one finished with a bamboo hoop brings a quiet sense of comfort.

While this tub does absorb some moisture,
depending on the season and what’s inside, water may still collect at the bottom.
If using the tub indoors, we recommend:
– placing it in a space like an entryway or concrete floor where moisture is less of a concern, or
– setting a tray or other surface underneath that can safely get wet.

Please store the tub in a cool, well-ventilated place, away from direct sunlight.
Also, please do not store the tub in a refrigerator.
Doing so may cause mold to form on the outer surface.
This tub is designed for year-round storage at room temperature.
In warmer months, it’s best to place it in a cool and well-ventilated area.

Wooden tubs have long been a part of daily life.
And once you learn how to care for them,
you may find they become one of the most reliable companions in your kitchen.

Pickling is a wonderful way to preserve vegetables—
and to enjoy ones you might not be able to eat in large quantities when raw.
Nukazuke is a form of fermented food, and with a mindful approach to salt,
it’s a healthy and delicious part of daily life.

Using a well-crafted sawara tub like this can bring both joy and depth
to your pickling experience.

Please be sure to check the size and choose the one that feels right for you.

Care Instructions

• Before use, gently wipe the inside of the bento box with a damp cloth.
• After use, wash both the inside and outside of the tub carefully using salt or a powdered cleanser.
  Do not leave standing water in the bento box, as this can accelerate the deterioration of the wood.
• After washing and drying,
  spraying the inside with sanitizing alcohol (ethanol) can help prevent mold and discoloration.
• Allow the bento box to air-dry in a shaded, well-ventilated area—such as near a window or ventilation fan.
  Avoid direct sunlight, as rapid drying may cause the wood to shrink,
  leading to the hoop coming loose, cracking, or warping.
• Do not use a dishwasher or dish dryer.
• If the bento box will not be used for over a month, wrap the body and lid separately in paper or cloth.
  Store them in a cool, dry place with a stable temperature.
  Leave the lid open during storage.
  Keeping it closed or storing it in a plastic bag may cause sap or resin to form.
