The dollar stood at 146.125 yen on Tuesday, staying near a nine-month high of 146.565 hit last Thursday.
But anxiety over the weak yen appears less than a year ago as households are becoming accustomed to rising prices, he said.
The benefits of a weak yen are also becoming clearer due to Japan's re-opening of borders, which is reviving inbound tourism and domestic service-sector firms, he added.
"Public discontent over the weak yen isn't escalating to a scale seen last year," he said.
But authorities could intervene if the yen speeds up its pace of declines and breaches 150 to the dollar, he said.
