Kuroda Haruhiko is set to become the Bank of Japan's longest-serving governor on Wednesday, his 3,116th day in office. During his time in charge of the central bank, he has become known for overseeing one of the world's biggest monetary easing programs.
Kuroda took the helm in 2013 and quickly set about trying to drag Japan out of deflation.
He set a target of 2-percent inflation within roughly two years, and started pumping money into the markets to reach it.
Kuroda's easing program weakened the value of the yen against the dollar and lifted stock prices.
He and his fellow policymakers have stuck with the strategy for more than 8 years, but the inflation target continues to elude them.
The bank's aggressive bond-buying program has prompted concerns about Japan's fiscal health.
But Kuroda has been quick to defend his approach. He told a news conference last week that Japan would be much worse off without it.
He said, "A macroeconomic simulation has shown that without aggressive and persistent easing, Japan's growth rate and prices would have been much lower, and the job increases not nearly as large."
Kuroda has one-and-a-half years left until his second term ends in 2023. BOJ officials are increasingly skeptical that Japan will reach 2-percent inflation during his tenure.
