Regarding wording for Nutrient Content Claims

"Rich in calcium", "zero-fat", "30% less salt"... Regarding Nutrient Content Claims, "Food Labeling Standards" define the standards, and the labeling must meet the specified conditions.

Take a look at the examples of expressions below.

Examples of expression indicating the ability of a food to supplement nutrients, or to ensure the proper intake of certain nutrients/calories
(" The guideline for nutrition labeling based on Food Labeling Act" pg19)

(1) Indications of the ability of a food to supplement nutrients

Indications that it is "high" high XX, rich in XX, plenty of XX
Other indications similar to the above
Indications that it is "present/contained" source of XX, provides XX, XX contained, contains XX, XX used, XX added
Other indications similar to the above
Indications that it is "enhanced" 30% extra XX, 2 times more XX
Other indications that nutrients quantities have been enhanced compared to other foods

(2) Indications of the ability of a food to ensure the proper intake of certain nutrients/calories

Indications that it is "not present/contained" XX free, zero XX, non XX
Other indications similar to the above
Indications that it is "low" low XX, XX reduced, low in XX, XX light, diet XX
Other indications similar to the above
Indications that it is "reduced" 30% less XX, 10g less XX, 50% less XX
Other indications that nutrients quantities have been reduced compared to other foods

Indications that no sugars are added or indications that no sodium is added

Indications that "no sugars are added" no use of sugars, no sugar used
Other indications similar to the above*
(*Descriptions such as "non-sugar" and "sugarless" will follow the labeling standards for indications that sugars are not present/contained.)
Indications that "no sodium is added" no salt added, no salt used
Other indications similar to the above

With the above clarified, what kind of expressions are there in "other indications similar to the above"?

"The fact-finding survey 2018 on Nutrition Facts and labeling of Foods with Nutrient Function Claims in foods on market"(pg13) was posted on the website of the Consumer Affairs Agency in April 2020. It includes "plenty of dietary fibers" as the description example of Nutrient Content Claims other than the above mentioned.
It means "plenty of" dietary fibers (is contained).

If you try to label "Nutrient Content Claims" for the products you manufacture or sell, you might have to check the examples of the above expressions before considering the labeling. However, even if you do not intend to do so, there may be cases where "other indications similar to the above" are displayed.

In addition, Nutrient Content Claims indicated outside of the collective labeling frame ((for mandatory items in Japan) thereafter referred as "collective labeling") tend to draw attention. However, wordings indicated inside the collective labelling such as "Legal name: XX (the name of nutrients such as potassium, magnesium. etc.) contained in food" are considered to be one type of "Nutrient Content Claims".

"Nutrient Content Claims" indicate each intake of the nutrients whose deficiency or excessive intake affects the promotion and maintenance of the public health.

It seems like people are more concerned about their health and nutrition than ever before due to this COVID-19 pandemic. I suggest reading through the inspection results and guidelines we have introduced and checking your packaging and description examples again.
