How To Grow Potatoes

Every day we meet so many lovely people.... this kind lady was nice enough to tell me how we grow rice in Yudanaka. I've been in Japan for 13years now, at last I found out about something I've wondered about for over a decade!!!! Possibly rice can be more more productive than over staple diets? ...Potatoes, wheat.... What do you think? Watch the video and enjoy a view that I've waited for 13years for.
