Yuzu (also known as Japanese citron, Citrus junos, Japanese yuzu citrus, or Yuja) may not be as common as oranges or lemons, but once you discover it, this small citrus fruit leaves a lasting impression. With its intensely fragrant aroma, sharp tangy flavor, and impressive health benefits, yuzu has earned a special place in Japanese and Korean cuisine—and increasingly in global wellness conversations.
If you have ever tasted a dish with a bright citrus kick that feels deeper and more complex than lemon, chances are yuzu was involved. But yuzu is not just about flavor. It also offers a surprising range of nutrients, antioxidants, and therapeutic properties that support overall health. Let’s take a closer look at yuzu fruit—what it is, how it benefits the body, how to consume it safely, and who should (and should not) include it in their diet.
What Is Yuzu?
Yuzu is a small, round citrus fruit that originated in East Asia, particularly China, and later became deeply rooted in Japanese and Korean food culture. It looks somewhat like a rough-skinned lemon or small grapefruit, with a thick, bumpy rind that turns yellow when ripe.
Unlike sweet citrus fruits, yuzu is rarely eaten on its own. Its juice is extremely sour, and its peel is intensely aromatic. Because of this, yuzu is mainly used as a flavoring ingredient rather than a snack fruit. In Japan, yuzu is used in everything from sauces and soups to desserts, beverages, cosmetics, and even traditional baths. Over time, its health-supporting properties and unique flavor have made it popular worldwide.
