Canon is preparing to move 50% of their production back to Japan by 2015:
"Japanese imaging and optical equipment maker Canon plans to return 50% of its production on-shore by the year 2015. Chairman and CEO Fujio Mitarai cited the weak yen and expenses of manufacturing overseas as the main reasons for moving back production to Japan."
Introducing automated production and robots should offset the expenses of moving back the production in Japan.
