But new board member Goushi Kataoka dissented to the BOJ's decision to maintain its interest rate targets, saying current monetary policy was insufficient to push inflation up to 2 percent during fiscal 2019.
At a rate review on July 19-20, the Bank of Japan is set to keep monetary policy steady and offer a more upbeat assessment of the economy than it did in June to say it is expanding moderately, said sources familiar with the central bank's thinking.
"It will be difficult for the BOJ to adopt what it has to do for an exit strategy whoever takes the post," said Takeshi Minami, chief economist at Norinchukin Research Institute, who saw no reason to replace Kuroda.
Speaking at a lower house fiscal and monetary policy committee meeting, Kuroda affirmed yield curve control as the main focus of monetary policy.
Speaking in the lower house fiscal and monetary policy committee, Kuroda said that the BOJ would adjust policy if needed, but that the central bank had recently upgraded Japan's economic outlook and the global economy was growing stronger.
"Infrastructure needs are huge and it's simply not possible for the Asian Development Bank and the World Bank to fill the gap completely," Kuroda, who was formerly head of the ADB, tolda seminar hosted by an ADB-affiliated think tank.
Kuroda also said that while Japan's economic prospects were brightening, inflation was lacking momentum and justified maintaining the BOJ's massive monetary stimulus for some time.
Kuroda, speaking in the upper house of parliament, also said he felt the BOJ would be able to manage its exit smoothly, including reducing the size of its balance sheet.
There is still a year left in Kuroda's current five-year stint, and the selection process won't begin in earnest until the latter half of this year, but some of Prime Minister Shinzo Abe's closest aides and senior financial officials say reappointment is a real possibility.
Kuroda also dismissed financial market concerns that the BOJ will eventually lose its ability to control long-term interest rates under its yield-curve-control framework.
"While some improvements have been observed in economic and price developments, there is still a long way to go to achieve our price target," Kuroda said in a speech at a Reuters Newsmaker event.
In a widely expected move, the BOJ maintained the 0.1 percent interest it charges on a portion of excess reserves that financial institutions park at the central bank.
Takehiro Sato and Takahide Kiuchi have been thorns in Kuroda's side since he launched his radical monetary experiment in 2013, consistently warning of the demerits of the BOJ's huge asset purchases and dissenting to many proposals to ramp up stimulus.
Kuroda said Japan's economic growth was accelerating and keeping inflation on track to hit the BOJ's 2 percent target during the fiscal year ending in March 2019, in line with its latest quarterly forecasts made in November.
Markets are also focusing on what BOJ Governor Haruhiko Kuroda has to say on US President Donald Trump's protectionist trade stance, particularly with Trump taking direct aim at Japan's powerful auto industry - a mainstay of its economy.
As the annual talkfest of the rich and powerful from across the world reached its last day here, top economic leaders felt the global economy is improving though mostly on internal factors even as they warned of new 'black swan' events post elections in various countries.
The Bank of Japan (BOJ) left policy unchanged on Tuesday at the conclusion of its two-day policy meeting, as widely expected.
BOJ Governor Haruhiko Kuroda has said the central bank may slow the pace of money printing if it can hit its interest rate targets, set under a policy revamp in September, with fewer asset purchases.
Japan's economic growth handily beat expectations in the July-September period, expanding for a third straight quarter as exports recovered, but weak domestic activity cast doubt on hopes for a sustainable economic recovery.
The Bank of Japan has for the past three years embarked on a bond-buying stimulus programme to try to keep interest rates ultra-low and increase borrowing and spending.
Clinton held a five percentage point lead over Republican rival Donald Trump, according to a Reuters/Ipsos opinion poll released on Monday, down only slightly since the FBI said last week it was reviewing new emails in its investigation of the former secretary of state ahead of the November 8 election.
While the sluggish indicators come as little surprise to policymakers, Friday's numbers add to a recent run of gloomy data that will keep the Bank of Japan under pressure to maintain an aggressive stimulus programme.
In a clear departure from his initial "shock and awe" tactics to jolt the nation from its deflationary mindset, he has even taken to flagging what little change lies ahead, trying predictability where surprise has failed.
With policy on hold, the nine-member board may also debate some operational details of its new policy framework adopted last month, such as to what extent the central bank could slow its bond purchases if yields fall below target.
But some regions warned of weakness in private consumption including the Tokai central Japan region, home to auto giant Toyota Motor Corp, where a strong yen hurt corporate profits and dampened consumer sentiment.
