The next president of the Asian Development Bank should also come from Japan after the five-year term of the current chief, former government official Haruhiko Kuroda, comes to an end in 2016, according to a senior ADB official.

Robert Orr, ADB's executive director and the U.S. ambassador to the bank, said in an interview Wednesday he is "certain that the next president will be from Japan. I would be shocked if he were not."

Since the launch of the multilateral lender in 1966, Japan has supplied all eight ADB presidents and criticism is growing over its dominance of the top post.
