How sensitive is Japan to slowdown in the USA? Sure Japan's biggest trade is with China, the USA accounts for only 20% of Japanese trade with other countries.

Goldman Sachs is predicting that Japan is already in a recession. Its new weakness is is its two tier workforce with lower wages and no benefits for part time workers, leading to lower consumption.
