What are the support center's business hours?

Please contact us via email.

We generally respond to inquiries in the order received during business hours (weekdays: 9:30–12:00 / 13:00–18:00).

Depending on the nature of the inquiry, it may take some time to provide a response.

Please note that inquiries received on weekends, national holidays, or during year-end/New Year and summer holiday periods will be addressed on the next business day or later.
