Following the Fukushima accident, the ongoing instability at the nuclear plant significantly disrupted the power supply in northeastern Japan, necessitating the implementation of temporary power outages and rolling blackouts.1

These energy uncertainties, combined with the physical destruction of infrastructure caused by the earthquake and tsunami, severely hampered the region's manufacturing output in the months following the disaster. Industries that were particularly affected included those involved in the production of automobiles and high-technology items, such as semiconductors. However, by late summer 2011, many businesses had resumed at least limited production, and industrial output largely returned to pre-disaster levels by early 2012.1
