Prosecutors have questioned a managing director of Mitsui & Co. over his alleged role in interfering with bidding for a Japan-funded power plant project on a Russian-held island in 2000, informed sources said Wednesday.
The Tokyo District Public Prosecutor's Office is investigating whether the man played a role in the alleged bid-rigging for the Kunashiri Island project as a supervisor to Masahide Iino, 44, head of a Mitsui industry project team, and two other employees.
Iino, Yusuke Shimazaki, 38, and Masayuki Takekoshi, 28, were arrested July 3 on suspicion of interfering with the bidding for the project on the island northeast of Hokkaido.
