On Japanese food, 賞味期限 (shōmi kigen) means “best-before,” while 消費期限 (shōhi kigen) means “use-by.” A best-before date primarily concerns expected quality; a use-by date is a safety-focused deadline and food should not be consumed after it. Both dates assume that the package is unopened and stored exactly as instructed.
Indian shoppers may also see an English importer label declaring “Expiry/Use By” and sometimes “Best Before.” Always follow the current label applied for sale in India rather than interpreting the Japanese date in isolation.
Best-before vs expiry/use-by: quick comparison
| Date marking | Japanese term | What it tells you | What shoppers should do |
|---|---|---|---|
| Best before | 賞味期限 | The date until which an unopened, correctly stored product is expected to retain its intended quality | Use before the date for the best taste and texture; follow the India label and seller guidance |
| Use by | 消費期限 | A safety-focused deadline for foods that can deteriorate relatively quickly | Do not consume after the date |
| Expiry/Use By in India | May appear on an importer-applied English label | The applicable last-use declaration for sale in India | Do not consume after the declared date |
| Manufacture/packing date | 製造年月日 or related wording | When the food was manufactured or packed | Do not confuse it with the final consumption date |
What does 賞味期限 mean?
賞味期限 (shōmi kigen) is Japan’s best-before date. It indicates the period during which the unopened product should maintain its expected flavour, texture and overall quality when stored according to the label.
Japan commonly uses best-before dates for shelf-stable products that do not deteriorate rapidly, such as:
- Potato chips and savoury snacks
- Biscuits and packaged chocolate
- Instant noodles and cup noodles
- Tea and coffee
- Seasonings and sauces
- Canned or retort foods
- Some candies and gummies
Japan’s Consumer Affairs Agency explains that a product passing its best-before date does not automatically become inedible at midnight. However, that does not mean every product remains suitable after the date. Actual condition depends on packaging integrity, storage history, formulation, climate and how long the date has passed.
For imported food in India, customers should follow the English importer label, the retailer’s policy and any product-specific directions. Japanned does not recommend treating a passed date as permission to consume a product.
What does 消費期限 mean?
消費期限 (shōhi kigen) is Japan’s use-by date. It is used for products where safety can decline comparatively quickly, even when the food has been handled correctly.
Examples may include:
- Fresh bento meals
- Sandwiches
- Prepared delicatessen food
- Fresh cakes and desserts
- Some refrigerated foods
- Other short-shelf-life products
Food should not be consumed after a use-by date. Appearance or smell cannot reliably prove that a food is free from harmful microorganisms. This is particularly important for children, pregnant people, older adults and anyone with reduced immunity.
The most important condition: unopened and stored correctly
Japanese date markings are normally established on the assumption that:
- The original seal remains intact.
- The food has been stored at the temperature stated on the package.
- The product has been protected from sunlight, heat and excessive humidity.
- The package has not been punctured, swollen, leaking or otherwise damaged.
Once a pack is opened, the printed best-before or use-by date may no longer describe how long the food will remain suitable. Follow after-opening instructions and consume the product promptly.

What Indian shoppers will see on imported Japanese food
Imported Japanese food sold in India can carry two sets of information:
- The original Japanese package, showing the manufacturer’s Japanese declarations.
- An English label for the Indian market, showing the applicable importer, ingredients, allergens, date marking and other required information.
Under the current FSSAI Labelling and Display Regulations, “Date of manufacture or packaging” and “Expiry/Use by” are declared, while “Best before” may also appear as optional or additional information.
This difference matters: a Japanese pack may prominently show 賞味期限, while the Indian label can use the terminology required for its sale in India. Shoppers should not remove the English sticker or rely on a machine translation of one Japanese phrase.
How to locate the date on Japanese packaging
Look for 賞味期限 or 消費期限 near one of these locations:
- The back label near the ingredients
- The bottom of a box or can
- The sealed edge of a pouch
- The bottle neck or cap
- A phrase directing you elsewhere, such as “printed outside the frame”
Common supporting phrases
| Japanese | Possible meaning |
|---|---|
| 枠外に記載 | Printed outside the box or designated frame |
| 底面に記載 | Printed on the bottom |
| 側面に記載 | Printed on the side |
| 製造年月日 | Date of manufacture |
| ロット / 製造記号 | Lot or production code |
A production code is not necessarily a date. If the numbers are unclear, send a complete photograph—including the wording beside the code—to the seller or importer.
How are Japanese dates written?
Japanese food dates are commonly arranged in year-month-day order, but the number of elements and punctuation can vary. A product with a longer shelf life may display only a year and month where permitted, while another may include a full date.
Examples of possible formats include:
- 2027.08.15 — commonly read as 15 August 2027
- 27.08.15 — may use a shortened year, but confirm the nearby wording
- 2027年8月15日 — 15 August 2027
- 2027.08 — year and month only
Never guess an ambiguous date. Compare it with the Indian importer label and ask for clarification if the format or printing is uncertain.
Best-before does not mean manufacture date
A common mistake is to see an old-looking number and assume the product has expired. First identify what the number represents.
| Term | Japanese | Purpose |
|---|---|---|
| Best before | 賞味期限 | Quality date |
| Use by | 消費期限 | Safety-focused last-use date |
| Manufacture date | 製造年月日 | Date of production |
| Lot code | ロット / 製造記号 | Production traceability |
Do not calculate an expiry date from a manufacture date unless the label or manufacturer explicitly provides the shelf-life period and calculation method.
Can Japanese food be eaten after the best-before date?
A passed best-before date concerns expected quality and does not automatically prove that an unopened product became unsafe at that exact moment. That is the general distinction made by Japan’s date-labelling system. It is not, however, a universal recommendation to eat imported food after the date.
Do not consume the product when:
- The Indian label’s Expiry/Use By date has passed.
- The Japanese label shows 消費期限 and that date has passed.
- The seal is broken or the package is swollen, leaking, punctured or badly damaged.
- The food required refrigeration and its temperature history is uncertain.
- There are signs of mould, infestation, fermentation where none is intended, or an abnormal odour.
- The date or product identity cannot be confirmed.
- The manufacturer or importer advises against consumption.
People at greater risk from foodborne illness should apply particularly cautious standards and seek professional guidance when necessary.
Why Indian weather changes the practical risk
India’s summer heat and monsoon humidity can damage food quality faster when storage instructions are ignored. Long shelf life does not make a product heat-proof.
Chocolate
Heat can cause cocoa butter or sugar bloom, creating a pale or whitish surface. Bloom is generally a quality change rather than proof of spoilage, but it does not override the printed date, package condition or storage instructions.
Seaweed and rice crackers
Humidity can make nori and senbei lose crispness. Reseal immediately and keep them dry.
Matcha, tea and coffee
Air, moisture, light and heat can weaken aroma and flavour after opening. Use airtight storage and follow the pack’s refrigeration guidance where applicable.
Gummies and candy
Heat may soften, deform or fuse pieces together. A texture change is not enough on its own to determine safety.
Instant ramen and seasonings
Moisture can affect noodles and powdered soup sachets. Do not use sachets that are leaking, damp, inflated or damaged.
What to do when the Japanese and Indian dates appear different
- Keep the product unopened.
- Photograph the complete Japanese date area and the full English importer label.
- Check whether one number is a manufacture or lot code.
- Contact the seller or importer with the product name, batch number and photographs.
- Do not consume the product until the discrepancy is resolved.
A sticker placed over part of the original package is not automatically suspicious; import labels sometimes need practical placement on limited packaging space. However, the required information should remain available and internally consistent.
Can a seller extend or replace the manufacturer’s date?
A retailer should not invent, overwrite or privately extend a manufacturer’s date. Any Indian declaration must be based on valid product and regulatory information. If a date appears altered, erased, inconsistent or unsupported, do not consume the product and contact the seller or importer.
How Japanned customers should check deliveries
When your Japanese food order arrives:
- Check the external parcel for heat, moisture or crushing damage.
- Inspect each product seal and package.
- Locate the English importer label.
- Confirm the Expiry/Use By or Best Before information.
- Read the storage instructions before putting the product away.
- Contact customer support promptly if anything is unclear.

Frequently asked questions
Is 賞味期限 an expiry date?
賞味期限 is more accurately translated as best-before. It concerns expected quality for an unopened product stored as instructed. Follow the Indian importer label for the declaration applicable to the product’s sale in India.
Is 消費期限 the same as use-by?
Yes. 消費期限 is Japan’s safety-focused use-by date. Do not consume food after this date.
Does Japanese food expire at the beginning or end of the printed day?
The printed date identifies the labelled day under the applicable system. Do not attempt to extend the period by calculating hours, time zones or purchase time.
Why does my Japanese pack show only a year and month?
Some longer-life foods may use a year-and-month format. Confirm the nearby wording and the English importer label rather than assuming a missing day.
Does the best-before date still apply after opening?
Not as a guarantee. Printed date markings generally assume the product is unopened. After opening, follow the specific refrigeration and consume-promptly instructions.
Can I rely on smell to check food past its use-by date?
No. Harmful microorganisms are not always detectable by smell, taste or appearance. Do not consume food after a use-by or expiry date.
Is white chocolate bloom the same as expiry?
No. Bloom is a physical quality change caused by fat or sugar movement, often related to temperature. The printed date, seal, storage history and overall condition must still be checked.
What if the printed date has rubbed off?
Do not guess. Keep the pack unopened and contact the seller or importer with the batch details and photographs.
Final takeaway
賞味期限 means best-before; 消費期限 means use-by. Best-before primarily concerns quality, while use-by is safety-focused. Neither date protects a product that was opened, damaged or stored incorrectly. Indian shoppers should always check the English importer label, follow its Expiry/Use By declaration and ask for clarification whenever the date format or package condition is uncertain.
The official distinction is explained by the Consumer Affairs Agency of Japan. Regulatory requirements and product formulations can change, so the current physical label always takes precedence.
Food-safety note: This article provides general consumer information and is not a product-specific safety assessment. If a use-by/expiry date has passed or the packaging and storage history are uncertain, do not consume the food.
