ah ok. thanks. i'm going to visit japan for a month or so. i thought about tokio, matsumoto, nagoya, region kyoto and fukuoka. but i can arrange my itinerary;-)
Here are contact details of the government/municipality of the places you're planning to visit. I'd like to suggest to contact them and ask if they can help you to find/meet the rice farmers.
Official website of Matsumoto-shi (Matsumoto city)
http://www.city.matsumoto.nagano.jp/english/Internationalcenter/index.html
At the very bottom of the page you'll find the contact details for their Public Information & International Liaison Division.
I cannot find such information for Nagoya city or
Aichi prefecture (where Nagoya is located), but here's the Front Desk number for Aichi prefecture.
As it is shown on the English version page, I assume they speak English as well.
