Makoto Takahashi, president of KDDI (au), who caused a communication failure, said at a press conference on the 3rd that he would consider compensation for users. However, the terms and conditions stipulating the contract rules for personal mobile phone services stipulate that "compens damages" if the service is not available at all or the same condition is continuous for more than 24 hours. It is unclear whether this "difficult situation to use" applies or not, and the actual response is likely to attract attention.
