I actually bought and tried the "Rocabo Biscuit Assort", a biscuit with 50% off sugar, sold by Seijo Ishii. The price is 690 yen per bag (excluding tax).
"Rocabo Biscuit Assortment" is a biscuit that uses not only wheat but also wheat and tofu powder for the dough to "50% off sugar" compared to general biscuits (Standard Tables of Food Composition in Japan 2015 "Soft" Compare with "biscuits").
A total of 7 bags of 2 types of assortment, "plain" and "tea" (4 plain, 3 tea). The nutrition facts label is as follows (per 15g (0.53oz) per bag).

■ Plain4 pieces in 1 bag. A round biscuit that is easy to throw into your mouth. It has a crispy and crunchy texture and is very fragrant! Personally, I like this crispy feeling, but because it is a type of biscuit that can bring moisture in the mouth, it may feel "dry" for some people. It is recommended to enjoy it with straight tea or black coffee.
■ Tea5 pieces in 1 bag. The texture is almost the same as plain. You will be healed by the slightly spreading scent of black tea. Is the black grain that can be seen here and there tea leaves? The part where the scent of black tea is not too intentional is also a good impression.
Seijo Ishii's "Rocabo Biscuits Assortment" has a sugar mass of less than 4g (0.14oz) per bag and you can enjoy it without feeling guilty. A bag of 4 to 5 pieces may seem a little expensive for about 100 yen, but it is an excellent snack in a low-carbohydrate diet.
