Support is available 24 hours a day, 7 days a week, including weekends and holidays, through the chat and the contact form. We work in English and Japanese. If neither is your first language, write to us in your own language anyway: we use translation tools and will do our best to help you in it.
Most questions are answered here in the help centre, and the chat points you to the right article first. If that doesn't settle it, the same chat connects you to a person. See How do I contact support?
