In 2008, Nikkei Business magazine carried out a survey of consumer electronics retailers which placed Yamada Denki at the bottom for consumer satisfaction. The company was displeased with this outcome and sued the Nikkei for 55 million yen in damages, claiming that the survey was not carried out as randomly as the publisher claimed. A judge has now ruled in favour of the magazine and dismissed the suit. In his opinion, the survey results were not produced arbitrarily so the magazine cannot be guilty of unfairly damaging the retailer's reputation. A Yamada spokesman has said they will immediately appeal.
