Origin of wasabi

The origin of this vegetable can be traced to Japan around 794 CE. The scientific name of this vegetable is Wasabia Japonica. The terms ‘Wasabia’ and ‘Japonica’ all have Japanese origins. Japan’s oldest encyclopedia of medical plants (known as Honzo-Wamyo) reveals that this plant was first known as Yamaoi, (Yama meaning mountain) for the mountainous geographical area where it was first discovered. Based on the physical appearance and growth region, the initial name evolved into what we know now. 

The development of this plant as a food began as far as the Nara period (710-793 AD). In the Mie Prefecture, a Japanese Buddhist monk (Koubou-Daishi) is believed to be the first person to see the bigger picture as he transplanted a cutting of this plant from Mount Koya to the area around the Chuzen-Ji temple. In the Yamaguchi Prefecture, the story goes that after the loss of the battle of Dannoura, in 1185, runaway Heike soldiers took cuttings of this plant from the Kidani-Kyo Gorge. They used the roots to garnish a nice meal for themselves, and also ate the stems and leaves of this plant. 


Every part of this plant is useful and has numerous functions. For instance, this plant can be used to prepare sauces and condiments. This plant is also used as a spice or flavoring agent. Components from this plant are even used to develop health products and cosmetics.

Commercial production

Japan is the leading producer of this plant, as it thrives well in the climatic conditions of its natural habitat in river valleys. This plant does not require direct sunlight. However, it can only thrive around 4,200-8,200 feet above sea level with an air temperature between 46.4°F (8°C) and 68°F (20°C). Anything more or less than this range would yield loss.


Real wasabi is very expensive, as the plant only thrives in special climatic conditions. Nonetheless, most of these plants are available in a green thick paste made from the combination of mustard, horseradish, and food coloring. Some forms of this product are paste, peas, powder, and roots. All of them last for different periods when left in a pantry or stored in the fridge. The shelf life of each form differs. 

This plant’s pastes and powders can be stored in a cool, dark pantry when unopened. Once opened, the paste can last up to twelve months in the refrigerator, and the powder can last half that time. The peas last from 2-3 weeks when unopened, and are better off left in a pantry. Once opened, they should be stored in the fridge. The roots last a day in the pantry and up to a month when refrigerated.
