First-Use Guide: What to Do When New Japanese Tableware Arrives

Unpack the piece carefully, check for damage and read the care instructions before washing or heating it. A porcelain plate may be ready after a gentle wash; a donabe may need seasoning, cooling and thorough drying. The right first step depends on what the object is made to do.

Use the chart to find your piece, then follow the relevant section. Each links to a fuller care guide for everyday use.

If the material or intended use is unclear, ask the seller first. A decorative vessel is not necessarily tableware, and neither a teapot nor a bowl is automatically suitable for the stove. Never scratch a finish to identify it.

Porcelain

New porcelain generally needs washing, not rice-water seasoning. Follow the care card for delicate decoration or repairs.

First wash:

1. Rinse with warm water on both sides.
2. Wash gently with a soft sponge and a small amount of mild dish soap.
3. Rinse and dry with a soft cloth.

Check microwave and dishwasher permissions separately before using either appliance. See the Japanese porcelain care guide for painted and gold-decorated pieces.

Cast iron tetsubin

For a kettle intended to boil water, follow its maker’s first-use routine. OIGEN’s kettle guidance is one example; another model may need a different method.

1. Rinse the inside gently as directed. Do not scour the interior coating.
2. Use the specified water quantity, water type and heat source; do not exceed the permitted fill level.
3. Follow the manufacturer’s boiling and discard sequence. Keep clear of steam and hot water.
4. Never let the kettle boil dry.
5. Empty as directed, turn off the heat and let the kettle’s retained warmth dry it. Do not put an empty kettle on a lit burner to dry.

The cast iron tetsubin care guide covers daily drying and rust.

An enamel-lined cast-iron teapot is for brewing tea. Follow its washing instructions and keep it off the burner unless its manufacturer explicitly permits heating that model.

Urushi lacquerware

A new lacquer bowl, tray or tea container needs care suited to its finish and construction:

1. If it has arrived very cold or warm, allow it to approach room temperature before cleaning.
2. Wash only if permitted for that object; some tea containers and decorated pieces are routinely dry-wiped.
3. For washable lacquerware, clean gently and dry with a soft cloth as directed.

Ask the maker or seller about a strong or persistent odour before use. See the urushi lacquerware care guide for washing and storage.

Donabe clay pot

Some donabe need rice-porridge seasoning, or medome (目止め); others specify different preparation. If your model calls for rice porridge:

1. Wash as directed, then dry the pot thoroughly, especially its exterior base, before applying heat.
2. Add the water and rice quantities given in the model’s instructions.
3. Heat gently on a compatible stove, with the pot’s exterior dry.
4. Attend the pot throughout cooking. Avoid boil-over, scorching and boiling dry; use the stated cooking time.
5. Turn off the heat and let the pot cool sufficiently before handling or washing. Do not cool a hot pot with cold water.
6. Discard the porridge once safe to handle, rinse as directed and dry thoroughly before storage or further heating.

Marumitsu’s instructions for its applicable heat-resistant pots illustrate why both drying before heating and cooling afterward belong in the preparation routine.

Seasoning does not make a pot crack-proof or change its heat compatibility. Allow enough time for cooling and complete drying. The donabe care guide covers cooking and subsequent care.

Edo Kiriko cut glass

For a new cut-glass drinking vessel, check the maker’s washing instructions:

1. Let a very cold or warm glass approach room temperature before washing.
2. Use water at a gentle temperature appropriate to the glass; avoid abrupt changes.
3. Wash gently with a soft cloth or sponge and a small amount of mild dish soap.
4. Rinse thoroughly with warm water.
5. Dry gently with a soft, lint-free cloth. Do not force the cloth into a narrow opening or twist the glass against its base.

Use a confirmed heat-resistant vessel for hot drinks; pre-warming ordinary cut glass does not make it heat-resistant. Check the product’s dishwasher instructions too. See the Edo Kiriko care guide.

Kyusu teapot

Check the pot’s clay or porcelain, finish and strainer before cleaning.

Before brewing:

1. Rinse as the maker directs, including the strainer. Do not scour or force the filter.
2. Check that the lid fits and the strainer is unobstructed.
3. Choose a water temperature suitable for the pot and the tea.
4. Brew according to the tea supplier’s recipe.
5. After brewing, empty the leaves promptly.
6. Rinse and dry fully with the lid separate.

Use a special first-use treatment only if the maker recommends one.

The kyusu care guide explains daily cleaning and the different types of strainer.

Matcha chasen and chawan

Clean the bowl, whisk, scoop and tea container separately; their routines differ.

Chasen first use:

1. Put clean water in a stable bowl. Hold the chasen by its handle and dip the tips for about 1–2 minutes before use, following Ippodo’s chasen guidance. Never pour hot water over a whisk resting in your hand.
2. Do not force the tips apart with your fingers.
3. Lift it by the handle and check for broken tips.

After whisking, rinse promptly without detergent and let it dry in the open air.

Chawan first use:

1. Wash or rinse the bowl as its maker directs.
2. Pre-wet only if recommended for that bowl; it will not permanently seal glaze crackle.
3. Dry the bowl thoroughly before storage.

Dry-wipe a traditional bamboo chashaku. For a natsume tea container, check the cleaning method for its material and finish.

See the matcha set care guide for drying, storage and when to replace a worn whisk.

Furin wind chime

Before hanging a new fūrin:

1. Check the suspension string. If it shows any fraying, replace before hanging.
2. Keep an intact original paper strip. Replace it if damaged, using the maker’s replacement or matching the original size and weight.
3. Choose a sheltered spot under an eave or roof overhang. Keep the bell out of driving rain and protect glass or painted finishes from prolonged direct sunlight.
4. Hang where the furin cannot swing against a wall, post, or another furin.

For storage, clean the finish as directed, dry completely and wrap. Keep iron bells off burners and avoid unapproved oils. See the furin care guide.

If you notice a smell, deposit or damage

An unfamiliar smell or mark deserves a closer look before use. Photograph it and contact the maker or seller, especially for:

• Persistent metallic taste or discoloured water from a kettle.
• A persistent smell from a clay teapot after its prescribed preparation.
• A strong or persistent smell from lacquerware.
• Loose residue or flaking on iron. Leave the interior treatment and mineral deposits undisturbed until you have advice.
• Cracks, leaks or unexplained marks on a donabe.

Do not use food, heat or improvised chemical treatments to test an unexplained defect.

Older or heirloom pieces

Inspect older pieces before applying a routine intended for a new product:

1. Look under good light for cracks, chips, flaking glaze or worn lacquer, and photograph any concerns.
2. Check for old repairs and identify their materials where possible.
3. Have leaks, structural cracks, unstable finishes or unknown repairs assessed. Rinsing or repeating a seasoning cycle cannot establish that an old piece is safe to use.

Keep an uncertain piece for display until its food-contact and heat suitability have been assessed.

FAQ

How much time should I allow before first use?

A washable plate may only need cleaning and drying. A donabe that needs seasoning also requires cooling and thorough drying afterward. Read the whole process before starting so those stages have enough time.

Does every new piece need water for first use?

No. A traditional bamboo scoop is normally dry-wiped; a whisk is rinsed. Tea containers and decorated objects have their own cleaning requirements. Check before wetting or soaking them.
