Wasabi is more than just a spicy condiment—it represents Japan’s refined culinary spirit. Used in sushi, soba, and other iconic dishes, wasabi enhances flavor while symbolizing purity and balance. This article explains wasabi’s origins, uses, and cultural role in Japanese cuisine for international readers.

What Is Wasabi? Basic Information

Botanical Features of Wasabi

Wasabi is a perennial plant that grows in Japan’s cool, freshwater mountain streams. The rhizome is grated to create a paste with a distinctive pungent aroma. The sharp, sinus-clearing sensation comes from a compound called allyl isothiocyanate, which is released when the plant’s cells are crushed.

In addition, wasabi has antibacterial properties, making it an ideal complement to raw fish in preventing food poisoning.
