Nikkei 225 rises as yen weakens

Tokyo's benchmark Nikkei Stock Average rose on Wednesday as a weaker yen spurred strong gains in export-oriented equities.

The Nikkei 225 ended the day at 40,762, gaining 0.9 percent from Tuesday.

Investors bought up export-related shares, including automakers, on the yen's depreciation against the dollar. The value of their sales overseas has been rising along with a stronger greenback.

On the Tokyo foreign exchange market, the Japanese yen briefly hit a 34-year low around noon.

Remarks by a Bank of Japan policy board member during the session may have sparked buying moves by investors. He said the relaxed monetary environment will remain in place for the time being.

The yen has continued to weaken against the dollar since the central bank's monetary decision on March 19.
