Fifty-three of the nation's top 100 companies have created sections for accepting in-house whistle-blowers' reports about wrongdoing in their companies, according to a Kyodo News survey released Monday.

One of the remaining 47 companies said it has devised a plan to set up such a section, with 30 others are considering setting up such sections, according to the survey of 100 firms selected according to such standards as profitability and public familiarity.

Seven of the 47 said they have arranged for existing departments, such as personnel affairs sections, to collect tips from whistle-blowers.
