The government is scrutinising more than 1,400 PV projects that were approved under its initial, highly generous ¥42 ($0.41) per kWh feed-in tariff (FIT), but which have since failed to move forward.

Judgment on the stuck projects will be meted out in two phases, with punishment likely to come in the form of a rescinded FIT offer.

Projects that have secured neither land rights nor a module-supply contract have until the end of March to do so.
