Can Japanese duty-free cosmetics and food not be used or eaten while in Japan?

Japan’s duty-free shops usually sell cosmetics and food that can be used when leaving Japan immediately after purchase. However, in some cases there may be restrictions or regulations.

For cosmetics, some brands may have expiration dates or other restrictions, such as they need to be used before a specific date or must be used within a certain time after opening. In addition, some cosmetics may be affected by environmental factors such as temperature or humidity, so it is recommended to read product instructions carefully and understand their storage and use before traveling.

For food, some may have shelf life limits or other restrictions, such as needing to be eaten by a specific date or must be kept at a specific temperature. Additionally, if the food needs to be refrigerated or frozen, you need to ensure that the correct temperature is maintained during transportation and storage.

In short, when purchasing cosmetics and food in duty-free shops, it is recommended to read the product descriptions carefully and understand their use and storage methods to ensure correct use and enjoy their advantages during travel.
