After announcing the Japanese economy will be saved, the impact of Japanese exchange rate on Japanese stock market and housing market for the market participants in the investment when there is a basis for reference. Through the smooth transition regression model, using exchange rate as threshold variable, and adding interest rates, price index and some economic variables, to explore the yen exchange rate under different thresholds, the Japanese real estate and the stock market will cause what impact changes. The empirical results point out that the yen exchange rate has a significant positive effect on stock price and real estate at less than or equal to the threshold. It is just the result that the policy may start fermenting after six months of Abe''s election. The Japanese government can observe the exchange rate in what range, by controlling the exchange rate to determine how Japan''s economic trends will change, and then with some policies, may make the Japanese economy to a longer future.
