Otsuka Soyjoy: Soy-Based Healthy Nutritious Snack Bars

When it comes to energy bars, many Japanese will probably think of Calorie Mate from Otsuka Pharmaceutical or Otsuka Seiyaku (大塚製薬). 

The product is Japan’s most-loved nutrition bar, put on the market in 1983, whose base is wheat, as often seen. However, these Soyjoy mainly consist of soy flour.

First released in 2006, Soyjoy is also a product from Otsuka Pharmaceutical.

These bars look similar to Calorie Mate. But based on the article on Japanese Wikipedia, they are not nutritional supplements but snacks.

As mentioned above, these Soyjoy bars mainly consist of powdered whole soybeans and contain no wheat, so they are gluten-free. 

Compared to Calorie Mate, the slightly moist baked dough incorporates more fruits, nuts, or other ingredients, which brings you more joy and satisfaction.

Besides, the bar packs nutrients equivalent to about 35 pieces of soybeans, including vegetable protein, soy isoflavones, and fibers, so it is a healthy, nutritious snack.

Otsuka offers four types of Soyjoy (fruit, nut, plant-based, and 80 kcal varieties), whose flavors are varied. Thus depending on your mood, you can choose what you want.
