UK-based Japanese vegetable growers

Really nice article here: about a Sussex-based farm that specialises in Japanese veggies. So glad to see enterprises like this, which probably make it a lot easier for London and South East restaurants to get fresher ingredients. I'd like to know if any UK bento-ers out there have used these guys' produce, or would consider it (I'm in Newcastle, so it's a bit far; maybe when I go and visit the folks!).
