The information found on the Japanese nutrition facts panel is often different from what is found in the United States of America or countries with a tightly regulated Nutrition/Food Labelling sector. Reason being, food manufacturers are not compelled to put a nutrition label on a food product. In fact, it is voluntary and left up to the sole discretion of the manufacturer. A label is only compelled when the product makes a nutritional claim "e.g, High in vitamin C or calcium". However imported food products generally require a nutrition label.
Here are some facts regarding the Japanese food label when it is present:
⌦ It provides vague nutrition and sometimes misleading information(e.g) it will show Total Fat but does not breakdown the components of the fat - Trans Fat, Cholesterol or even Saturated Fat amongst others.
(e.g) it will claim to be high in a particular vitamin or another nutrient, but this claim is only validated if the entire package is consumed.
⌦ Determining the serving size and nutritional content per size is a challenge.
The Japanese food label often provides the nutrition information per 100 grams (100 g) or 100 millilitres (100 ml). This does not translate into helpful information especially, if a food product has a net weight of 350 g or 540 ml. Can you estimate how much is 100 g of potato chips or cooked rice? For the calorie concerned person, the use of a calculator and or food scale is required to determine how much the recommended serving (100 g) translates into first. From there, determining whether a 100 g of the product is sufficient for their needs-food or diet.

This table should be helpful in deciphering the Japanese food label.
In all fairness food labels vary from country to country, but nevertheless they provide information that appears to be culturally significant to that region/country.
