Wasabi: Real vs Imitation
Authentic Japanese wasabi is rare, often replaced by imitation made from horseradish, mustard, and green food coloring. True wasabi comes from the Wasabia japonica plant, grown in riverbeds.

Wasabia japonica requires specific conditions: shaded, cool, running water, and rocky riverbeds. It's labor-intensive to cultivate and takes up to 18 months to mature, contributing to its rarity and cost.
Flavor and Texture
