On 26 May 2011, the JFTC found that four companies (Taiyo Nippon Sanso Corporation, Air Liquide Japan Ltd, Air Water Inc and Iwatani Corporation) had engaged in price-fixing activities in violation of Article 3 (prohibition of unreasonable restraint of trade) of the Antimonopoly Act. The four companies had reached an agreement to raise the selling price of specified air separation gases, by approximately 10% from their original prices, from at least January 2008. The JFTC issued a cease and desist order and imposed a surcharge payment in the amount of 14,104,850,000 yen. It is important to note that the JFTC also imposed a 50% increase on the total fine for those companies that had previously received a surcharge payment order in the last 10 years.
