The Bank of Japan raised its benchmark policy rate to a 31-year high of 1.25% from 1.0% at the conclusion of its monetary policy meeting on Friday.
The decision, approved by a 7-2 vote, was in line with market expectations and marked the second rate hike for the central bank this year.
The BOJ last raised its benchmark policy rate to 1.0% from 0.75% in June.
The central bank said Japan's economy is recovering moderately, although some weakness remains due geopolitical uncertainties acting as risks to the outlook.
The economy is expected to continue growing moderately, driven by rising global AI-related demand and various government measures, the BOJ said.
Rising crude oil prices and the depreciation of the yen have pushed medium- to long-term inflation expectations higher, bringing the underlying rate of consumer price inflation closer to the BOJ's 2% target.
