Tepco appointment stirs public anger in Japan
The cosy relationship between some of Japan's largest companies has been thrown into the spotlight.
The former president of Tokyo Electric Power (Tepco), the firm behind last year's devastating meltdown at the Fukushima nuclear power plant following the earthquake and tsunami, is to take up a position with Fuji Oil.
Masataka Shimizu had to stand down from Tepco, following the crisis. Tepco owns a significant share of Fuji Oil's parent company, AOC Holdings.
The BBC's Mariko Oi says there's much public anger over the appointment.
