Economic and fiscal policy minister Heizo Takenaka said Tuesday he plans to tell government officials and business leaders from East Asia about upbeat developments in Japan's economy when he attends a conference this weekend in Singapore.

"I would like to tell (them) how significantly the Japanese economy has changed over the last half-year," Takenaka said, citing rises in Tokyo stock prices from April to September that were the highest since 1972 on a half-year basis.
