Yamato Transport Co. said Tuesday it has sought a court injunction to halt Japan Post's parcel-handling tieup with convenience store operator Lawson Inc.
Yamato took this step at the Tokyo District Court because it views the alliance as unfair under the Antimonopoly Law.
Yamato believes Japan Post's full-fledged entry into the parcel delivery market via Lawson's nationwide network is unfair because Japan Post receives preferential treatment in taxation and other areas.
"We would like to pursue our claim in court that it is unfair competition" a Yamato spokesman said.
Lawson has agreed to handle Japan Post parcels from mid-November. This has angered Yamato, which has a tieup with the convenience store operator in the same sector.
Lawson has said it wants to renew its partnership contract with Yamato when the current contract expires on Nov. 19.
Yamato, however, decided in August to terminate its alliance with Lawson due to the latter's tieup deal with Japan Post.
A Japan Post official said Tuesday that the company is not doing anything wrong.
