Happy Customers

Don’t just take our word for it...

After spending 10 years based in Tokyo as an expat you accumulate a lot of correspondence which doesn’t go away the minute you leave. Thanks to MailMate bringing this service (finally) to Japan it was a worry I crossed off my list. The process is simple, online and offers various levels of service so you have choices. My mail is making it to me in South Korea regularly and securely.

Paul Hardisty, President & Representative Director - Sports Footwear & Apparel Industry

Mailmate's service has proven to be much, much more than virtual mail forwarding. They assist with getting me copies of all my Japanese correspondence, utility bills, and government notices, provide a bill payment facility when I am outside of Japan, and even help translate correspondence I don’t understand.

They’re practically my Japanese concierge at a fraction of the cost I was previously paying property managers, assistants, and translators, etc. for the same service(s).
