Contact

Reach us by email, phone, or fax during JST business hours, or send something physical to our Tokyo office if you still trust paper.

Best for filing questions, support invoices, and calmly worded explanations of what went wrong.

For issues that are easier to solve in one conversation than in twelve perfectly polite emails.

Fax

+81 3 6455 9271

Yes, this is Japan, we still use fax.

Office Hours

We keep Tokyo hours

If you contact us from another time zone, please interpret any delay as geographic reality rather than emotional distance.
