Wasabi , often hailed as Japan’s fiery green condiment, is a staple in Japanese cuisine, renowned for its sharp, pungent flavour that can transform any dish. It is derived from the Wasabia japonica plant, a member of the Brassicaceae family, which also includes mustard, horseradish, and cabbage. This guide looks into the world of wasabi known as Wasabia japonica offering insight into its history, culinary uses, and tips for incorporating this unique ingredient into your cooking repertoire.
The Origins of Wasabia japonica
The use of Wasabia japonica dates back to the Nara period (710-794 AD), originally utilised for its medicinal properties before making its way into the culinary scene. It was traditionally cultivated in the mountainous river valleys of Japan, a practice that continues in some regions today. The rarity and difficulty of growing Wasabia japonica make it a prized ingredient in Japanese cuisine.
Cultivation and Harvesting
Wasabia japonica is notoriously difficult to cultivate due to its need for specific conditions: clean, running water, a cool climate, and protection from direct sunlight. These requirements mean that Wasabia japonica is often grown in shaded, natural water streams in the mountainous regions of Japan. The plant takes about 12 to 18 months to mature, after which the stem, or rhizome, is harvested to produce wasabi.
Real Wasabi vs. Wasabi Substitutes
Most wasabi served outside of Japan is not real wasabia but a mixture of horseradish, mustard, starch, and green food colouring. This is because real wasabia is expensive and loses its flavour quickly once grated. Real wasabi rhizomes has a more complex flavour profile, with a unique, fiery heat that dissipates more rapidly than the lingering burn of horseradish.
Culinary Uses of Wasabi
Sushi and Sashimi

Wasabi in Other Dishes
Beyond sushi, wasabi can be used in various dishes, including salads and noodles, as a seasoning for meats. It is also popular as a flavouring for snacks, like wasabi peas. Wasabi’s pungency complements many dishes, adding depth and heat.
Health Benefits of Wasabi
Wasabia japonicasabi is not only valued for its flavour but also for its health benefits. It contains isothiocyanates, compounds known for their anti-inflammatory, antimicrobial, and potential cancer-preventing properties. Wasabi also aids digestion and can help prevent food poisoning, which is particularly beneficial when consuming raw fish.
How to Use Wasabi 101
When using real wasabi paste, it is best grated fresh, as its volatile compounds start to fade within minutes, losing its potency and flavour. A traditional wasabi grater, made of sharkskin, is typically used, but a fine metal grater can work as well. Due to its intensity, it is important to use wasabia sparingly.
Storing Wasabi 101
Fresh wasabi rhizomes should be wrapped in damp paper towels and stored in the refrigerator, where they can last for about a week. Wasabi paste should be kept in an airtight container in the fridge and used within a month for optimal flavour.
Conclusion
Wasabia japonica is a distinctive element of Japanese cuisine, celebrated for its unique heat and depth of flavour. While real wasabi paste may be challenging to find outside Japan, its growing popularity has made it more accessible in global markets. Whether you are a sushi aficionado or a culinary explorer, incorporating wasabia into your dishes can add an authentic Japanese twist to your meals. Remember, the key to enjoying wasabia is to use it sparingly, allowing its pungent flavour to complement rather than overpower your dish.
