Japanese copper cookware is valued for its fast, even heat conduction and precise temperature control. Most pieces are lined with tin, which protects food from reacting with copper and provides gentle, consistent heating. With proper care, copper cookware can be enjoyed daily for many years.
Before First Use
Copper Tamagoyaki Pan (Oil Seasoning – Abura-narashi)
- Wash gently with mild dish soap and a soft sponge.
- Fill the pan about halfway with cooking oil and heat slowly over low–medium heat for 4–5 minutes.
- Let cool, discard the oil, and wipe the interior clean with a paper towel.
Copper Cooking Pots
(Yukihira Pan, Donburi Pan, Shabu Shabu Pan)
- No seasoning required
- Wash with mild soap, rinse, and dry thoroughly before use
Using Copper Cookware
- Use low to medium heat—copper heats very quickly
- Keep the flame under the base; avoid letting it climb the sides
- Transfer food to another container after cooking, especially salty or acidic dishes
-
Do not use unlined copper with acidic ingredients (e.g., vinegar, citrus)
Cleaning After Use
Allow cookware to cool completely before cleaning.
Tamagoyaki Pan
- Wipe inside and outside with a paper towel
Cooking Pots
- Wash with warm water, mild soap, and a soft sponge
- Dry thoroughly to prevent tarnish
If verdigris (bluish-green tarnish) appears, gently clean with a soft cloth and cream-type cleanser. Verdigris is not harmful but may affect flavor.
Long-Term Storage
- Remove all moisture after washing
- Wrap in newspaper, place in a plastic bag, and store in a cool, dry area
- For extended storage, lightly oil the tin lining before wrapping
- Re-season before use if stored for a long period
Things to Avoid
- Never heat an empty pan (tin lining may melt)
- Avoid frying in copper cookware
- Do not use metal utensils, steel wool, or abrasive cleaners
- Do not use a dishwasher
- Do not leave food in the cookware after use
With regular use and simple care, Japanese copper cookware develops a rich patina and becomes increasingly responsive—making it a dependable and beautiful tool for everyday cooking.
