On 3rd April 2016 I was on an amazing study tour in Japan to witness first hand the cultivation of perennial vegetables. These are wild native species which were previously wild foraged in Japan but are now cultivated to meet demands for what is collectively known as sansai (mountain veggies). There’s a whole section of supermarkets devoted to sansai. The one we are most familiar with in the west is wasabi, but for most of us it is in name only as it is almost always horseradish, mustard and food colouring which are the ingredients of wasabi sauce offered in sushi bars, rather than genuine wasabi (Wasabia japonica).
The farm we visited was on the Izu peninsula, a popular tourist area. It was one of the most beautiful and naturalistic farms that I’ve witnessed anywhere and could be categorised as a permaculture forest garden with shade-loving wasabi growing in running water diverted from a river into an intricate series of neatly set out beds and intercropped with trees like loquat and other fruit. Most of the work seems to be done manually.
First, a few videos from the farm and below can be found an album of pictures of wasabi and other plants we saw, including at a shrine and associated vegetable garden adjacent to the farm! Wasabi has very narrower ecological requirements to produce well, including shade and running cool mountain spring water.
17th March 2019: I’m adding three pictures at the bottom of a group of “wild” wasabi plants growing in quite a dry shady environment in the hills near to Toyota in Japan!

One thought on “A visit to a Wasabi farm on the Izu peninsular in Japan”
From what I read, I think Wasabi would like Skye. At least if I can give it some wind protection! I’ve just ordered a couple of plants and am just working out where they may be happy….
