Can Japanese lacquerware go in the dishwasher?

No. Heat, water pressure and detergent together crack, cloud and peel the lacquer, and the rapid drying and temperature swings discolour and warp it. Wash in lukewarm water with a soft cloth and dry immediately.

Can lacquerware go in the microwave?

No. Microwave, oven and direct flame all cause major and immediate damage.

Does sunlight damage urushi?

Yes. UV degrades the urushi film itself, causing fading and surface cracking, so keep pieces out of direct sunlight including in storage.

Lacquerware survives generations by hand, and one dishwasher cycle.

Urushi is a natural resin film, not a coat of varnish. Everything that damages it is something people reasonably do to ordinary tableware without thinking, and none of it can be undone.

Cross-section of lacquerware. Urushi is a thin film of many coats over a wooden base. Intact, the surface is unbroken and glossy. Damaged, the film has crazed through and clouded, while the wooden base beneath is unchanged. — What you are looking after is the film, not the bowl. It is built up coat by coat over a base that moves with heat and moisture — which is why sudden heat, pressure and detergent craze it, and why the damage cannot be washed back out.

What destroys it

✗Dishwasher. Never. Heat, water pressure and detergent together crack, cloud and peel the lacquer; the rapid drying and temperature swings also discolour and warp it.
✗Microwave / oven / direct flame. Never. Causes major, immediate damage.
✗Direct sunlight. Avoid, including in storage. UV degrades the urushi film itself, causing fading and surface cracking.
✗Soaking / air drying. Do not leave it to soak or to dry on its own. Wash in lukewarm water with a soft cloth, rinse, and dry immediately.
✗Stacking. Put soft cloth or paper between pieces in storage.

Why it catches peopleEvery one of these is a normal, reasonable thing to do with Western tableware. Nothing about the object signals otherwise, and the damage is not reversible.

How these pages are put together. Written in Japan, but we do not own or test the pieces described here — the facts are compiled from makers, specialist retailers and published sources, and every one is listed at the foot of the page so you can check it yourself. Makers do change specifications, so confirm against the listing or the manual before buying. If something here is wrong, tell us and it gets corrected.

Where to look

Lacquerware is produced across Japan — Echizen, Yamanaka, Wajima and Aizu among the best-known centres. Prices vary enormously with how many coats of urushi are involved and whether the base is wood or a composite; ask before you assume.

Musubi Kiln — lacquerware ↗

One thing to carry into any shop, not just this one: 漢 lacquer on a label can mean natural urushi or a urethane coating, and general marketplaces rarely distinguish them. The two are not interchangeable — everything on this page applies to the first and none of it to the second. If a listing will not say which it is, treat that silence as the answer.
