Tokyo:Some of Japan's biggest firms including Sony and Toyota shut down operations in southern Japan today after the region was struck by a deadly earthquake, fuelling worries about disruption to supply lines and possible effects on the wider economy.
At least nine people were killed in Thursday night's 6.5-magnitude quake, which also toppled houses and buckled roads on the southwestern island of Kyushu.
With widespread damage to infrastructure, several companies -- including in the steel, auto and technology sectors -- said they had temporarily ceased production.
Exporter giants Toyota, Honda and Sony were carrying out safety checks assess possible damage to plants and those of suppliers.
Other firms shutting down included Mitsubishi Electric, Renesas and Fujifilm as well as tyre maker Bridgestone and beverage titan Suntory Holdings.
Sony shares were down around three percent in the afternoon, Toyota lost 1.2 percent and Honda was off 0.45 percent while Bridgestone lost 0.70 percent.
However, the broader Nikkei stock index was only slightly lower, with some of the losses also attributable to profit-taking after a strong rally this week.
Minister of Economy, Trade and Industry Motoo Hayashi told reporters the there had not been the devastation that tore into northern Japan after the 2011 quake.
"There are some companies that have stopped operations, but so far I've received no reports of huge impact such we had" in the March, 2011 quake, he said, according to Jiji Press
That quake unleashed a deadly tsunami that swallowed schools and entire neighbourhoods, killing more than 18,000 people and triggered reactor meltdowns that released radiation in the most dangerous nuclear disaster since Chernobyl in 1986.
It also led to the closure for several months of dozens of factories, decimating the country's production capacity and sending shockwaves through the already struggling economy.
Shattered supply chains and rolling power shortages forced companies such as Sony and Toyota to temporarily shut plants in the weeks after the disaster and Japan's industrial output tumbled by its largest amount on record in the March.
Many component manufacturers were based in the worst-hit regions and the disaster led to a call for firms to spread their operations to avoid a repeat of the widespread shutdown that hammered economic growth.
The latest quake comes as the economy struggles to get on track, with the government's growth drive stumbling and growth still tepid.
