Navigating the grocery store in Japan can be a bit daunting, especially when trying to decipher the dates on food packaging. Unlike some countries where there’s a single “expiration date,” Japan uses two terms: “shōmikigen” (賞味期限) and “shōhigen” (消費期限). Understanding the difference is crucial for ensuring food safety and avoiding waste.

The Two Dates: What They Mean

  • Shōmikigen (賞味期限): Best-by Date This date indicates the period during which the food is expected to maintain its optimal flavor, texture, and quality. It’s not necessarily unsafe to consume food after the shōmikigen, but the quality may have deteriorated. This date is typically found on items with a longer shelf life, such as: Snack foods (お菓子 – okashi) Canned goods (缶詰 – kanzume) Instant noodles (インスタントラーメン – insutantorāmen) Dry goods (乾燥食品 – kansō shokuhin)
  • Shōhigen (消費期限): Expiration Date This date indicates the point at which the food is no longer considered safe to consume. It’s crucial to adhere to the shōhigen to avoid food poisoning. This date is typically found on perishable items with a shorter shelf life, such as: Fresh meat (生肉 – namaniku) Fresh fish (生魚 – namazakana) Dairy products (乳製品 – nyūseihin) Prepared meals (お弁当 – obentō)

Examples to Clarify

  • Yogurt (ヨーグルト – yōguruto): You’ll likely see a shōhigen, as it’s a dairy product that can spoil relatively quickly. Consuming it after the shōhigen poses a risk of food poisoning.
  • Potato chips (ポテトチップス – poteto chippusu): These usually have a shōmikigen. Even after the date, they might still be safe to eat, but they might not taste as fresh or crispy.
  • Pre-made bento box (お弁当 – obentō): These almost always have a shōhigen. Because they contain numerous different food types, and are designed for quick consumption, it is very important to adhere to the shōhigen.

Key Points for Foreign Residents

  • Always check the dates on food packaging before purchasing.
  • When in doubt, it’s always safer to err on the side of caution and discard food that has passed its shōhigen.
  • Storing foods according to the storage instructions on the packaging will help them last as long as possible.
  • Learn to recognize the kanji for each term: 賞味期限 (shōmikigen) and 消費期限 (shōhigen).
  • Remember that proper storage plays a major role in food safety, regardless of the dates.

Preventing Food Waste

  • Plan your meals and grocery shopping to avoid buying more than you need.
  • Store food properly to extend its shelf life.
  • Use your senses: if food smells or looks off, it’s best to discard it, even if the date hasn’t passed.

By understanding the difference between shōmikigen and shōhigen, you can make informed decisions about your food and ensure a safe and enjoyable culinary experience in Japan.
