"If you are a global investor and you're seeking a diversification of risk in your portfolio, what's very interesting is that the dependency of, let's say the Chinese equity market, on what's happening in the U.S. is becoming less and less," said Jim McCafferty, joint-head of APAC equity research at Nomura.

The Bank of Japan, after maintaining its ultra-low interest rates last week, released the minutes from its April monetary policy meeting on Wednesday morning.

"Many members expressed the view that underlying inflation, measured by the CPI excluding such factors as energy, remained relatively low," the minutes said.

Most members of BOJ policy board expect short-term and long-term interest rates to remain at their present levels or lower, the minutes added.

The Japanese yen crossed the 136 level on Tuesday and was last at 136.19 against the greenback. The currency has been weakening as the Bank of Japan's monetary policy diverges from that of the Fed.

Experts previously told CNBC that the main focus of the central bank is not exchange rates but inflation.
