Abstract: Recent Studies in the area of foreign exchange market efficiency have employed time series analysis to test for the absence of long‐run equilibrium or cointegration relationships among the exchange rates for the major currencies. Cointegration directly violates the weak form of the Efficient Market Hypothesis in a speculative efficient market (Granger, 1986). In this study, we address the efficiency of the Tokyo spot foreign exchange market while updating the test procedures developed by Phillips and Ouliaris (1990), Johansen and Juselius (1990) and Johansen (1991). Cointegration is found to be absent, showing that the Tokyo spot market is consistent with the efficient market hypothesis.
