A wooden hangiri, also called a sushi oke, is a traditional Japanese tub used to prepare sushi rice.
Because it is made from natural wood, proper care is important. Preparing it before first use, wiping it before each use, washing it promptly, and drying it properly can help keep the tub in good condition.
This guide explains how to care for a wooden hangiri at home.
Before First Use
Before using a new wooden hangiri for the first time, prepare the wood gently.
Method 1: Using Rice-Washing Water
Fill the hangiri with rice-washing water (the cloudy water collected when rinsing rice) and let it sit for approximately 2 hours.
Then rinse thoroughly with clean water and dry in a shaded, well-ventilated area.
Method 2: Using Vinegar and Water
If rice-washing water is not available, you can use a vinegar-and-water mixture instead.
Fill the hangiri with water and add 2β3 small cups of vinegar. Let it soak for 2β3 hours, then rinse it lightly with clean water.
Both methods can help reduce the natural scent of new wood and prepare the surface before making sushi rice.
These soaking methods are intended for first-use preparation only. For regular cleaning, avoid leaving the hangiri filled with water for a long time.
Before Each Use
Before adding freshly cooked rice, rinse the inside of the hangiri lightly with water, then wipe away excess moisture with a clean cloth.
The wood should be lightly damp, not wet. Remove any standing water before adding the rice.
Lightly dampening the surface can help reduce the chance of odors, stains, or discoloration. It can also help prevent the dry wood from absorbing too much moisture from the hot rice at once.
After Use
After using the hangiri, wash it promptly with water or warm water.
If needed, use a mild, neutral-pH kitchen detergent. Avoid harsh cleaners, strongly scented detergents, and abrasive scrubbers, as natural wood can absorb odors and may be damaged by rough cleaning.
After washing, rinse the hangiri lightly and wipe away excess water.
Dry it thoroughly, upside down, in a shaded, well-ventilated area.
Avoid direct sunlight, as rapid drying may cause the wood to shrink, warp, crack, or loosen the bands.
How to Store a Wooden Hangiri
Store the hangiri only after it is fully dry.
A cardboard box or breathable bag is suitable for storage.
Do not seal the hangiri in a plastic bag while moisture remains, as trapped moisture may cause odors, staining, or mold.
Store it in a dry place away from direct sunlight, heaters, air conditioners, and high humidity.
What to Avoid
To keep a wooden hangiri in good condition, avoid the following:
- Leaving water inside for a long time during regular use
- Dishwasher
- Microwave
- Oven
- Heated dish dryer
- Direct sunlight
- Strong airflow from heaters or air conditioners
- Sealed storage while damp
- Harsh or strongly scented cleaners
Wood is a natural material, so changes in color, grain, and tone may occur over time. These changes are part of the character of wooden kitchenware.

Frequently Asked Questions
Can I use vinegar instead of rice-washing water before the first use?
Yes. Rice-washing water is one option for preparing a new wooden hangiri, but a vinegar-and-water mixture can also be used.
If using vinegar, fill the tub with water, add 2β3 small cups of vinegar, and let it soak for 2β3 hours. Rinse lightly with clean water afterward.
Can I wash a wooden hangiri with dish soap?
Yes, when needed.
Use a mild, neutral-pH kitchen detergent, then rinse lightly and dry the hangiri properly. Avoid strongly scented or harsh cleaning products.
Can a hangiri go in the dishwasher?
No. A wooden hangiri should not be placed in a dishwasher.
Dishwasher heat, strong water pressure, and prolonged exposure to moisture may cause the wood to warp, crack, shrink, or loosen.
Why should I avoid direct sunlight?
Direct sunlight can dry the wood too quickly.
Rapid drying may cause shrinking, warping, cracking, or loosening of the bands. A shaded, well-ventilated area is best.
When should I store the hangiri?
Store the hangiri only after it is fully dry.
A cardboard box or breathable bag is recommended. Avoid sealed storage while the wood is still damp.
