TOKYO, Oct 27 (Reuters) - Japan's core consumer prices rose 0.7 percent in September from a year earlier to mark a ninth straight rising month, offering the central bank some hope that economic recovery is helping to drive inflation towards its 2 percent target.
The data will be among factors the Bank of Japan will scrutinise when it updates its long-term growth and price projections at next week's rate review.
The gain in the nationwide core consumer price index, which includes oil products but excludes volatile fresh food prices, compared with a median market forecast for a 0.8 percent gain and followed a 0.7 percent increase in August.
Stripping away the effect of fresh food and energy, consumer prices rose 0.2 percent in September from a year ago, data from the internal affairs ministry showed on Friday.
Core consumer prices in Tokyo, available a month before the nationwide data, were up 0.6 percent in October from a year earlier, against a median forecast for a 0.5 percent rise. It was the fastest annual pace since March 2015.
Japan's economy expanded at an annualised 2.5 percent in the second quarter as consumer and corporate spending picked up, with steady growth likely to be sustained in coming quarters.
But inflation remains distant from the BOJ's 2 percent target with companies reluctant to raise prices for fear of scaring away cost-sensitive consumers.
The BOJ is set to largely maintain its price forecasts at its policy meeting next week, blaming stagnant inflation on factors such as corporate efforts to boost productivity, and signalling that it will hold off on expanding stimulus for the time being.
