Worldwide Opportunities on Organic Farms (WWOOF, pron.: /ˈwʊf/), or Willing Workers on Organic Farms, is a loose network of national organisations that facilitate placement of volunteers on organic farms.
(...)
WWOOFing aims to provide volunteers with first-hand experience in organic and ecologically sound growing methods, to help the organic movement, and to let volunteers experience life in a rural setting or a different country. WWOOF volunteers ('WWOOFers') generally do not receive financial payment. The host provides food, accommodation, and opportunities to learn, in exchange for assistance with farming or gardening activities.
The duration of the visit can range from a few days to years. Workdays average five to six hours, and participants interact with WWOOFers from other countries. WWOOF farms include private gardens through smallholdings, allotments, and commercial farms.

I'd like to do a WWOOF course in Hokkaido soon. I'm a UK resident so I'm allowed to stay in Japan for up to ninety days without a Visa, so I'm hoping to spend nearly three months in the country.
Even though I've been studying Japanese for a year, I'm terrified. I'm sure I can get to Japan without a problem but navigating my way from Tokyo to Sapporo sounds like a nightmare. I'm thinking about flying between the two cities so I don't have to deal with confusing trains or bus rides.
