From NHK World: July 22, 2011. 37 nuclear reactors in Japan, or nearly 70 percent of them, remain shut. This includes 2 reactors operated by Kansai Electric Power Company in Fukui Prefecture that were recently closed for regular inspections.

According to the plant operators, inspections for 11 of the 37 reactors will finish by August. But it is still unknown when any of these will be resumed due to the government's new stress-test requirements announced earlier this month.

The remaining 17 reactors that are currently in operation will also be brought to a halt for regular inspections every 13 months. Among these is the Kansai Electric Ohi power plant No. 4 reactor in Fukui Prefecture that will shut down by Saturday. An additional 3 reactors will be brought to a halt by August.

Among the 13 other reactors in operation, 5 will be stopped by autumn, 6 by winter, and 2 by spring.
This would leave Japan with no nuclear reactors in operation by spring next year.
