【UPDATE】 This is only for customers in areas struck by the disaster.

Softbank and Docomo have both announced that they would not be charging their customers in Kumamoto for extra data usage. Docomo, Softbank, and AU have also said that customers have until the end of May to pay their April bill (for those who pay with a bill sent through the mail only; those who pay through automatic withdrawal will still be billed per usual) . They are offering support (lender phones/reduction in repair fees) for customers whose phones were damage in the earthquakes, so please contact a branch for assistance. As always, if you need Japanese language support, you have only to ask and it will be provided.
