Japan's consumer price index in September rose for the fourth straight month as energy prices increased due to the weaker yen.
The Internal Affairs Ministry says the index stood at 100.5 in September against a base of 100 for 2010.
That's up 0.7 percent from the same month last year.
The index excludes volatile fresh food prices.
The inflation index, which excludes food and energy prices, was flat in September from a year earlier at 98.5. The declining trend came to a halt for the first time in almost five years.
Ministry officials attribute this to the continued rise in gasoline prices and power rates as a result of the weaker yen and instability in the Middle East.
They add that the prices of durable leisure goods, such as computers, TVs and printers, have risen for two consecutive months for the first time since January 1992.
The officials say the nationwide index showed smaller growth than the previous month, but the leading index for Tokyo's 23 wards has increased. They are hopeful that this growth trend will spread to the rest of the country.
