UK-based Japanese vegetable growers

Really nice article here: http://search.japantimes.co.jp/cgi-bin/nn20100922f2.html 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!).
