Japan earthquake: One month on

Available for over a year

A month after the Japanese earthquake and tsunami, the BBC's Mariko Oi in Tokyo joins Lesley Curwen in London to look at how badly the country's economy has been hit and how it might be repaired. Mariko Oi talked to the Japanese economics minister, Kaoru Yosano who said power black-outs could go on for three to five years. He also said it was not the right time for Japan to decide whether to change its nuclear policy. Shinji Taniguchi, production manager at Furukawa Electric's Totsuka factory explained the difficulties of working with rolling black-outs. And Hiromasa Yonekura, the chairman of the Japan Business Federation said it was time to unite and help rebuild the devastated Tohoku area. Duncan Bartlett reports from Tokyo on how individuals have responded to the crisis, and whether people are prepared to stop mourning and start spending again. And Lesley Curwen talks to Steve Agg, chief executive of the Chartered Institute of Logistics and Transport about how Japan's disaster has interrupted global supply chains. Will this mean big companies source fewer components from Japan in future?
