When it comes to health and longevity, Japan has long been admired for its balanced lifestyle, nutritious cuisine, and natural remedies. Among its many health secrets, Aojiru — commonly known as Japanese green juice — stands out as a simple yet powerful way to boost your daily nutrition.
What Is Japanese Green Juice?
Japanese green juice, or Aojiru (青汁), literally means “green juice” in Japanese. Traditionally made from kale or young barley grass (yomogi or aojiru no moto), this vibrant green drink is packed with nutrients and has been a staple in many Japanese households since the 1940s.
Originally developed by Dr. Niro Endo as a way to treat his family's health issues, Aojiru has evolved into a national health drink embraced by everyone from busy office workers to health-conscious elders.
Key Benefits of Japanese Green Juice
-
Rich in Vitamins & Minerals
Aojiru is loaded with vitamin C, vitamin A, potassium, calcium, and iron — all essential for immune support, bone health, and overall wellness. -
Digestive Health
The high fiber content promotes regular bowel movements and supports gut health, making it an excellent natural remedy for constipation. -
Detox and Cleanse
Chlorophyll-rich greens like kale and barley grass help cleanse the body by removing toxins and improving liver function. -
Antioxidant Power
Aojiru contains a high level of antioxidants which combat free radicals, reduce inflammation, and may even slow signs of aging. -
Convenient Nutrition Boost
Whether you're skipping meals or just need an energy pick-me-up, a small serving of green juice offers an easy and quick nutrient boost.
What Does It Taste Like?
Let’s be honest — traditional Aojiru has a strong, grassy, and bitter flavor. For this reason, it’s often considered an acquired taste. But modern blends often include matcha, yuzu, apple, or honey to improve palatability while preserving its health benefits.
