TOKYO: Japan's economy grew for the eighth straight quarter at the end of 2017, government data showed Wednesday, its longest period of expansion since the "bubble" boom days of the late 1980s.
Gross domestic product in the fourth quarter of last year expanded 0.1 percent from the previous three months, the Cabinet Office said, reports AFP.
But the growth rate fell short of market expectations of 0.2 percent and represented a slowdown from the 0.6 percent in July-September.
At an annualised rate, the world's third largest economy grew 0.5 percent.
"The growth rate for the last quarter was very low compared with the bubble period but the economy is solid enough," said Takeshi Minami, chief economist at Norinchukin Research Institute.
"There are lingering worries over consumption but we can expect the economy to pick up further if 'shunto' wage hikes are better than the previous years," he said, referring to collective wage negotiations between labour and management held every spring.
"The current expansion could be extended further," he told AFP.
For the calendar year 2017, the economy grew 1.6 percent, against 0.9-percent in 2016.
Japan's Minister for Economy, Trade and Industry Toshimitsu Motegi said the current expansion was solid compared with the more volatile "bubble" boom in the 1980s, according to Bloomberg News.
Amid speculative investment in land and stocks on low interest rates, the Nikkei stock index hit almost 40,000 in 1989 -- nearly double its current level.
The bubble burst at the start of the 1990s, ushering in a period of low or no growth known as the "lost decades".
The current period of growth is good news for Prime Minister Shinzo Abe, who has been trying to fire up the economy with his pro-spending policy dubbed Abenomics since he took office in late 2012.
Junko Nishioka, chief economist at Sumitomo Mitsui Banking Corp., also said an uptick in income suggested the Japanese economy would expand further.
Abenomics is providing "a wide range of tax measures quite beneficial to Japanese firms", she said, with the current expansion phase less reliant on exports.
"Compared to the bubble economy, the Japanese corporate sector is very cautious in its investment, in other words the signs of a bubble are contained compared to 30 years ago," Nishioka added.
Bank of Japan Governor Haruhiko Kuroda, who looks set to stay at the helm until 2023, has vowed to maintain a loose monetary policy given still weak inflation..
