Tokyo: Japan's consumer prices rose 3.2 per cent from a year earlier in April to the highest level since 1991, the government said on Friday, largely due to a sales tax increase.
Other April data for the world's third-largest economy were largely in line with forecasts. Industrial production fell 2.5 per cent from a year earlier and household spending sank 4.6 per cent. Unemployment was 3.6 per cent, the same as in March.
Japan raised its sales tax to eight per cent in April from five per cent. Japan's central bank estimates that 1.7 percentage points of the inflation rate in April could be attributed to the tax hike. The 3.2 per cent figure is for the core consumer price index, which excludes fresh food.
Prime Minister Shinzo Abe's policies aimed at ending a deflationary slump that has slowed growth for nearly two decades have made some headway, though the inflation rate remains well below the two per cent target set by the central bank and government when the tax hike is factored out.
Consumers and businesses ramped up spending ahead of the increase, boosting demand temporarily. The economy is expected to contract or at least slow sharply this quarter.
Economists say a sustained recovery will hinge on strong consumer demand, and that requires wage increases to catch up with the higher prices.
Shortages of labour in some areas, such as construction and trucking, have been pushing prices and to a limited extent wages higher. But so far overall incomes have not kept pace with the tax hike and price increases.
Prices in Japan were pushed up last year by increases in costs for energy as the yen weakened against the dollar because of massive monetary easing. Many businesses raised prices or offered less for the same price to compensate for their own higher costs.
Revving up consumer demand through stronger purchasing power will be crucial, said Stephan Danninger, Asia and Pacific division chief for the International Monetary Fund.
"The need for inflation to be meaningful in contributing to a stable and faster growing economy is through demand and not through the input of higher prices," he told a seminar in Tokyo on Friday.
The dollar is now buying about 101 yen compared with 80 yen two years ago. But the yen's recent stabilisation near 101 to the dollar means inflation is getting less of a push from the exchange rate than it did last year.
"The sharp fall in import price inflation points to a slowdown in consumer inflation in coming months, which should provide some relief to households' battered finances," Capital Economics analyst Marcel Thieliant said in a commentary.
Massive monetary easing by the Bank of Japan has mainly given the government leeway to work on reforms needed to enhance Japan's competitiveness in the longer run and to repair government finances, said Masaaki Kanno, chief economist at JP Morgan in Tokyo.
The April 1 tax hike and a further 2 percentage point increase planned for next year are part of the government's effort to bring Japan's huge public debt, which is more than twice the size of the economy, under control.
"One of the most important roles is for the BOJ to buy time," said Kanno.
