Service-sector inflation is being closely watched by the Bank of Japan for clues on whether demand-driven price gains are broadening enough to justify raising interest rates further.
The November year-on-year gain in the services producer price index, which measures the price companies charge each other for services, accelerated from a 2.9% gain in October, BOJ data showed.
The BOJ ended negative interest rates in March and raised its short-term policy rate to 0.25% in July on the view that Japan was making steady progress towards durably achieving its 2% inflation target.
Governor Kazuo Ueda has said the BOJ will keep raising rates if inflation remains on track to stably hit 2% as it projects.
