The lack of electricity in Japan is due to several nuclear power plants being shut down since the 11 March disasters.  They were planning on restarting this month, but, because of the ongoing disaster at Fukushima Daiichi, they will delay longer.

Hamaoka nuclear plant in Shizuoka Prefecture, Shika nuclear power plant in  Ishikawa Prefecture, and, Genkai nuclear power plant in Saga Prefecture, have all delayed their planned restarts.  This will make the problem of international parts supplies even worse.

Nuclear plant officials say it’s not just the ongoing disaster at Fukushima Daiichi, but the fact that the Japanese government has ordered nuke plants to increase structural protection against natural disasters.  That will take time.
