Competition Law (the Act on Prohibition of Private Monopolization and Maintenance of Fair Trade, the Act against Delay in Payment of Subcontract Proceeds, Etc. to Subcontractors, the Act against Unjustifiable Premiums and Misleading Representations, etc.) is an area of law in which directors and officers often inadvertently find themselves in breach of various regulations. The consequences of a breach of competition law can be quite serious, especially in instances where a company is ordered to pay a significant administrative penalty or criminal sanctions are imposed.
For these reasons, our firm places great importance on identifying potential competition law problems in clients’ businesses before they arise, addressing each issue through dialogue, and raising awareness of relevant legislation among clients.
In regard to cartels and bid rigging, the firm deals not only with large-scale international and domestic cases involving dealings with the Japan Fair Trade Commission, such as applications for a surcharge reduction under the current leniency system and the establishment of ex post facto compliance systems, but also with notifications in response to the business combination regulations required at the time of implementing the M&A process. Furthermore, our firm handles a wide range of cases, including negotiation and litigation with regard to unfair trade practices as well as the provision of advice on dispute prevention by ensuring the exclusion of unfair contract terms in compliance with competition laws, particularly in cases where there is an imbalance of power between the parties.
