The World Bank has a positive view on the Japanese economy despite the awful impacts of the earthquake and tsunami.

Singapore, March 21, 2011 Japan real GDP growth will slow, but the slowdown
will likely be temporary, as a result of the earthquake and tsunami and growth
should start picking up after mid-2011 as reconstruction efforts get underway,
says the World Bank in its latest East Asia and Pacific Economic Update
released today. While it is still too early for a full assessment, Japan痴
past experience suggests an accelerated reconstruction effort, and the short
term impact on the economies of developing East Asia is likely to be limited.
