A Central Japan Railway Co. official is suspected of leaking information to construction firm Obayashi Corp. during the tender process for maglev train-related construction work, sources said Tuesday.
The special investigation squad of the Tokyo District Public Prosecutor's Office has been looking into the case, questioning the official and an Obayashi executive among others. Investigators suspect Obayashi gained an advantage over its competitors by obtaining inside information from the railway operator, which is also known as JR Tokai.
JR Tokai said it will conduct an in-house probe.
