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.
The central bank slightly cut its inflation forecast for this fiscal year in a quarterly review of its projections, suggesting that it will maintain its massive monetary stimulus for the time being to achieve its ambitious 2 percent target.
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.
Any such downgrade of the BOJ's 1.5 percent inflation target will make it difficult for the central bank to seek an early exit from its massive stimulus, said Kazuo Momma, a former BOJ official who oversaw its monetary policy and international affairs.
Service-sector sentiment improved for the first time in six quarters and companies remained upbeat on their capital expenditure plans, the Bank of Japan's "tankan" survey showed, offering hope the economic recovery will gather momentum in coming months.
The Bank of Japan's quarterly tankan business sentiment survey will likely show the headline index for big manufacturers' sentiment improved by four points to plus 14 in March from plus 10 in December, the poll of 19 economists found.
But household spending remained soft and consumer inflation was flat when stripping away the effect of rising energy costs, underscoring the challenges the Bank of Japan faces in generating sustained price rises backed by steady wage growth.
Members dismissed the notion that the BOJ would have to raise its 10-year government bond yield target due to gains in bond yields overseas, and instead said it should focus solely on the domestic economy.
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.
Fitch said that the recent US rate hikes could mark the beginning of a significant shift in global interest rate environment, with benchmark US policy rates settling higher over the long-term than current market expectations.
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.
Core machinery orders, a highly volatile data series regarded as a leading indicator of capital spending, probably rose 0.5 percent in January after a 6.7 percent gain in December, a Reuters poll of 14 economists found.
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.
The yen's volatility seen in 2016, when it rose sharply against the dollar in the first half of the year before falling toward year-end, made it hard for Japanese firms to do business, Masai said in a speech in Zurich, Switzerland, on Monday.
Sato also said the BOJ should not persist in maintaining the current pace of government bond purchases and consider reducing its massive holdings of treasury discount bills, since it now targets interest rates and not the pace of money printing.
The move comes after the central bank's erratic bond operation since late January confused market players, leading to a surge in Japanese Government Bond yields to one-year highs earlier this month.
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.
Scrambling for capital, Toshiba said it would consider selling most, even all, of its stake in the chips business - a decision that has investors questioning whether the company has a long-term future without the unit.
Members also believed it was appropriate for the BOJ to maintain its current ultra-easy policy, with one member even arguing that the central bank should not change policy hastily.
