Ken Yagi, a deputy director general of the Finance Ministry's International Bureau, will soon become Japan's next executive director at the International Monetary Fund, a senior ministry official said Friday.

Yagi, who will succeed Yukio Yoshimura, will be formally named as Tokyo's top representative at the Washington-based lending agency around July 10, the official said.

The appointment will be conducted as part of the ministry's annual personnel reshuffle.

Yagi, who once served as a senior official at the Asian Development Bank, has been in his current position since July 1998. Yoshimura has been Japan's executive director at the IMF since February 1997.
