Gluten-Free Furikake: What Japanese Labels Can and Can't Tell You
Japanese labels declare wheat, not every gluten grain. 9 of 28 products list no wheat, but that does not prove they are gluten-free.
Not a celiac-safe list. Japan's labeling rules don't cover barley or rye, "brewed vinegar" and starch syrup may come from gluten grains without saying so, and shared lines aren't disclosed. "No listed wheat" is the strongest statement a Japanese label supports.
How we check this
A product qualifies if the allergen list does not include the "wheat" code, and the full Japanese ingredient text has no additional mention of 小麦 (wheat) that our automated flag might have missed. There is no dedicated "wheat" contains_flag on Japanese labels — wheat is only ever recorded as a mandatory allergen code — so this list uses the allergen code as its primary signal.

Questions about this list
Is furikake gluten-free?
Not provably, from a Japanese label alone — wheat is the only gluten grain Japan requires manufacturers to declare. Even a product with no listed wheat can't be confirmed gluten-free without checking barley, rye, oats, and cross-contact directly with the manufacturer.
Why is soy sauce a problem?
Traditional Japanese soy sauce (shoyu) is typically brewed from wheat and soybeans together, so a furikake seasoned with soy sauce usually lists wheat as an ingredient — one of the most common reasons a product doesn't make this list.
Is "gluten-free" on a Japanese package the same as in the US/EU?
Not necessarily. Gluten-free labeling standards and testing thresholds differ by country, and Japan's mandatory allergen system covers wheat specifically, not "gluten" as a category. Always check the specific certification or standard a package claims, rather than assuming equivalence.
