Getting the country past the virus will be job No. 1, requiring a road map for reopening after the latest virus emergency ends this week and more stimulus to woo voters before national elections this fall.

Then comes the harder part: boosting innovation and tackling other long-simmering problems that have eroded Japan’s prosperity and made it the slowest growing nation in the Group of Seven.
