Complete Wasabi Guide

If you’ve ever eaten sushi, you know about wasabi. It’s green and sort of spicy, the kind of spicy that burns through the nose. Pretty awesome, right?

It dawned on me that after many years in Japan, I knew very little about this plant.
I mean, was it even a condiment? How’s it grown? Where does it come from? How much does fresh wasabi really cost? Is it a root?
I had a lot of questions. Daio Wasabi Farm in Nagano had all the answers!

DAIO WASABI FARM is in Nagano Prefecture, a three hour drive or train ride from Tokyo.
Not only do they grow fresh wasabi, Nagano one of the best places in the world to cultivate it and try it fresh. This place is huge! Daio has covered an entire river bed to give the wasabi plant shade.
That’s right. Wasabi is grown in the water.
Each bush os always submerged and wasabi is not a root at all. It’s the stem.
This is why calling it “Japanese Horseradish” is wrong because it’s not horseradish at all.

Oh, and the farm was also a location in a Kurosawa film so that sealed the deal for me to visit.

Let’s get an inside look at these wasabi plants down on the river.
Home sweet home. This is where wasabi resides in Japan.

Wasabi needs a cool place with constant fresh water.

This variety of wasabi is called “hon wasabi” and is used most commonly with sushi. It’s also popular with foods like steak and washoku dishes.

The fresh water that melts from the Japanese alps surrounding it is loaded with the necessary minerals for the wasabi to thrive.

I plucked it from the soil like a carrot, but unlike the carrot, the wasabi stem is covered with leaves and roots to protect it.

Where’s the wasabi?

Here it is! I had to wash off some of the soil and tear off the roots and leaves to get to that spicy stem.

The things with wasabi is that you need to eat it fast,
The taste goes away 15 minutes after grating. This is the main reason why wasabi is placed under the sushi – it holds the flavor and kick longer.

It’s important to note that the green leaves from the wasabi root are also popular in cooking. They have a strong bitter taste and most likely full of vitamins

Some consider wasabi to be one of the superfoods with a ton of health properties.
It could be true. All I know is that those wasabi vapors really kick you in the face every time.
There’s got to be something good about that, right?
