Rebuilding northeast Japan to take years, billions

Six oil refineries that can turn 1.4 million barrels of oil a day into fuel - a third of Japan's refining capacity - are shut down, two due to fires. An out of control blaze at one refinery is raging for a sixth day.
Steel plants have also been hit.
Nippon Steel Corp.'s factory in Kamaishi, Iwate Prefecture was shut after the tsunami flooded part of the plant. The facility makes steel and wire rods for vehicle powertrains and chassis. Sumitomo Metal Industries Ltd. plant in Kashima, Ibaraki prefecture also went dark after the earthquake.
Elsewhere, widespread power shortages from damage to four nuclear plants - an unfolding crisis in itself - have forced many companies to halt production.
Sony Corp. has halted output at several factories, including one that makes Blu-Ray discs. Toshiba Corp. has done the same. All automakers including Toyota Motor Corp., the world's biggest, have stopped making cars nationwide.
Companies are also facing problems shipping components, receiving raw materials and getting workers to facilities that are working, said Dale Ford, an analyst at technology market research firm IHS iSuppli.
The components made by Japan's hi-tech industry are destined for final assembly in China and other countries. Analysts said there's enough inventory in the global supply chain to tide over customers up to four weeks and companies such as Apple, Dell and Lenovo will have to switch to backup sources by then to avoid shortages of parts for iPads and computers.
Initial estimates of insurance losses from the disaster range as high as $60 billion.
