A massive 8.9 magnitude earthquake and tsunami struck the northeast coast of Japan on Friday, the strongest quake in Japan since records began, causing widespread destruction and probably killing at least 1,300 people.

Here is the impact on manufacturers, energy firms and other companies with facilities in northeastern Japan.

MANUFACTURING

- Sony Corp said it had suspended operations at six production facilities in the affected area. One factory was flooded, while the other five did not suffer major damage, the company said.

- Nissan Motor Co said it had halted production at all four of its car assembly factories in Japan, including those in severely hit Tochigi and Fukushima prefectures. Small fires broke out at two of the factories.

- Toyota Motor Co said it had halted production at two factories with combined annual capacity of 420,000 small cars built mainly for overseas markets.

- Honda Motor Co said a 43-year-old male employee had died at its R&D centre in Tochigi prefecture after a wall collapsed in the canteen, while about 30 people were injured. It said four of its domestic plants and a research and development center will remain shuttered on Monday.

- Fuji Heavy Industries Ltd said it had halted eight of its 10 factories, including all five car and car parts-related plants for its Subaru-brand vehicles in Gunma prefecture, north of Tokyo. It also suspended operations at its aircraft and power products factories in Tochigi.

- Kirin Holdings said four large beer tanks had collapsed and some of the contents had been washed away at a factory in Sendai. Operations were also suspended at its factory in Ibaraki after part of the facility was damaged.

Other companies said they had halted operations of their plants in the region as workers were evacuated following tsunami warnings or due to power outages. They include Asahi Kasei Corp , GlaxoSmithKline , JSR , Nestle , Nippon Paper Group , Sapporo Breweries Ltd and Morinaga Milk Industry .

NUCLEAR, UTILITIES

- The government said there had been an explosion at Tokyo Electric Power Co's Fukushima nuclear plant, some 240 km (150 miles) north of Tokyo, but it had not yet confirmed whether the explosion was at a reactor.

TEPCO has been working to reduce pressure in the core of the reactor of the plant damaged by the quake. The outer structure of the building that houses the reactor appeared to have blown off, TV footage showed, which could suggest the containment building had already been breached. Tens of thousands of residents have already been evacuated from the vicinity.

- TEPCO also said it foresaw a power shortage of 7 million KW on Sunday and 10 million KW on weekdays, and would consider asking customers to accept outages in turns from Sunday.

- Electric Power Development (J-Power) has halted operations at its Isogo thermal plant in Yokohama, Jiji news reported.

- Tokyo Gas Co said it has stopped supplying gas to more than 35,000 households and facilities in the Kanto area in eastern Japan.

REFINERS

- JX Holdings said a fire at its Sendai refinery had originated from a land oil product shipping facility nearby, not an LPG tank as feared earlier.
