Retire in Japan through buying into a business?

Hi,

I was looking into farming in Japan, specifically fruit orchards as a late in life goal.
Currently I am working in government development planning with a BSc in environmental issues.
It seems that buying a farm is not a simple process and I'd more likely find a route by being a partner in a business with locals handling most of the day to day.
Am I missing something that absolutely stops my hopes of getting into agriculture and business in Japan from Canada?
