PRACTICAL BUYER GUIDE
What “made in Japan” means on a dog-food label
Separate the product’s country of origin from ingredient origin, brand ownership and the address of a Japanese seller or importer.

Five label fields answer different questions
Japanese pet-food law requires the product name, best-before date, ingredients, country of origin, and the responsible business name and address to appear in Japanese. A package may separately identify a manufacturer, importer or seller.
A Japanese company address or Japanese brand does not by itself mean that the product was manufactured in Japan. Read the field labelled 原産国 or 原産国名 for the product’s declared country of origin.
Country of origin follows the last substantial process
The Ministry of Agriculture, Forestry and Fisheries explains that origin is generally the country where the final process that substantially changed the product was completed. Merely repacking a finished product does not make the repacking country its origin.
The relevant process depends on the product. Official examples include extrusion for dry kibble. Adding flavour after imported kibble has been formed may not change its origin, while processing raw meat into jerky can be the substantial final process.
Ingredient origin is a separate statement
Japan’s pet-food law does not generally require the origin of every ingredient. A voluntary claim about Japanese chicken or another ingredient must therefore be read separately from the origin of the finished food. “Made in Japan” does not promise that every ingredient came from Japan.
For a medical or allergy-related restriction, do not infer ingredient provenance from the single word 国産. Use the latest complete ingredient statement, a manufacturer response and veterinary guidance.
A practical check for Rakuten listings
Match the exact product name, flavour, life stage and pack size first. Then locate the origin field and note whether the named Japanese business is the manufacturer, importer or seller. Multi-variant listings can show different specifications, so confirm the selected option and compare it again with the delivered package.
Country of origin is useful identification data, but it does not rank nutritional adequacy, ingredient quality or suitability for an individual dog. Compare purpose, life stage, guaranteed analysis, energy and feeding directions as well.
