A company connected to the former secretary of a senior politician received more than 10 million yen from construction companies in return for introducing local government heads and major contractors, industry sources said.

A former secretary to House of Representatives member Michihiko Kano, deputy head of the Democratic Party of Japan, the main opposition party, is a board member of Gyosai-Toshikaihatsu Kenkyusho (Gyosaiken), a consultant company based in Chiyoda Ward, Tokyo.

The sources alleged Tuesday that the company received commissions from construction firms for introducing them to local government heads and general contractors in relation to public works projects nationwide.
