Okara Day (Okara no Kara no Hi)

What Is Okara Day?

Every year on January 30th, Japan celebrates "Okara Day." The date comes from a wordplay (goroawase) on the numbers: in Japanese, "0" can be read as "o," "3" as "ka," and "0" as "ra," together spelling out "o-ka-ra" -- okara. The day was established by Mutsuo Iemura, an "okara revival producer." Okara is the byproduct left over after pressing soy milk from soybeans, but it's actually a remarkably nutritious and versatile ingredient. This day aims to spread awareness of okara's health benefits and culinary uses, while also raising awareness about reducing food waste.

Okara: A Treasure Trove Packed With "The Source of Life"

Okara is often thought of as just leftover pulp from making soy milk or tofu, but it's actually packed with the nutrients of soybeans. It's especially rich in dietary fiber -- reportedly about twice as much as burdock root. It also contains plant-based protein, calcium, potassium, and soy isoflavones, making it a "superfood" ideal for filling nutritional gaps common in modern diets.

The Beautiful Name "U-no-hana"

In Japan, okara has long been known by the poetic name "u-no-hana" (deutzia flower). This name comes from the resemblance between okara's pure white appearance and the white flowers of the deutzia shrub, which blooms in early summer. Okara is also a symbol of the traditional Japanese spirit of "shimatsu" -- using ingredients carefully and without waste.

The Evolving Uses of Okara

Beyond the traditional simmered dish "u-no-hana itari," okara's health benefits have made it popular in Western-style recipes too. Used in place of flour, it can lower the carb content of baked goods and bread. Added as a binder to hamburger patties or fish cakes, it boosts volume while cutting calories. Because it has such a mild flavor, it blends easily into almost any dish.

SDGs and "Dried Okara"

Because okara has high water content and spoils easily, much of it was historically thrown away. Recently, however, improved technology has made it possible to turn okara into a fine, dry powder -- "okara powder" (dried okara). This allows for long-term storage and easy use, simply sprinkled into drinks or miso soup, achieving both food waste reduction and better health.

The Appeal of Okara

• Its outstanding dietary fiber content is expected to help support gut health
• Rich in compounds like soy saponins and soy isoflavones, which are great for skin health and menopause care
• Low in carbs and calories, yet filling -- perfect for dieting
• Affordable, and sometimes even free, making it gentle on the household budget
• Doesn't overpower other flavors, so it works well for bulking up dishes or adding texture

Tips for Enjoying Okara

If you're worried about okara being too dry, the trick is to pair it with ingredients that bring fat (such as mayonnaise or olive oil) or extra moisture. Try seasoning it like potato salad, or mix it into donuts or cookies for a moist, chewy texture. With a bit of creativity, okara can become a surprisingly delicious dish.

Tips for Enjoying Okara Day

• Make a hearty bowl of "u-no-hana" simmered okara for dinner
• Try making pancakes or muffins using okara powder instead of flour
• Visit a local tofu shop and pick up some fresh "raw okara"
• Share your favorite okara recipe on social media to spread the word

The Wisdom of Living Healthily Without Waste

Okara Day is a chance to remember the beautiful Japanese spirit of using every part of an ingredient to its fullest. Thrown away, it's just waste -- but used well, it's a wonderfully healthy dish. On January 30th, why not put a warm, white okara dish on your table and give your body a refreshing reset from the inside?
