Japan was part of my territory back in the day, spent a lot of time there. We were taken to a wasabi 'farm' during a holiday which consisted of a whole system of stream diversions off of a mountain side. I couldn't even see the wasabi plants until someone pointed them out to me. They're raised in the running water through very loose soil, right along the banks of the stream. Not sure if it's possible to grow it without the running water part(?). Maybe as an element of an aquaponics scheme?

Well, no shortage of water here. I'm in a rainforest. my battle is usually things rotting & not being warm enough. I'd have to over winter them here in a high tunnel.
I have searched for wasabi in the past with zero results.
Even in Japan, they are a much guarded secret - like truffles in Italy - nobody wants to give up their source.
Thanks, I did see that also. For some reason they don't want to ship to Alaska:( Bums me out because I have ordered from them before. Are you getting some? I did find a source through "Hirt" seeds. Got the plants & so far so good. They are small plants & lost many leaves in the shipping.
