Warning about suspicious e-mails claiming to be from our company

Recently, we have been receiving unsolicited e-mails claiming to be from our company.

However, we have never sent out such unsolicited e-mails, and we believe that they are “spoofed e-mails” sent by spoofing the sender’s name to our domain.
Please be aware that we have nothing to do with this.


The following is an example of an email that was actually sent.

From: (Our domain is included.)
Subject: Subject: Commercial offer.

Body text:

Hello, thank you very much for your interest.

〜The content is a request for bitcoin transfer in faltering Japanese.〜


These e-mails were not sent from our mail server but were sent from a different server with a spoofed sender.

If you receive a suspicious email claiming to be from us, please delete it immediately.
– Delete the email immediately.
– Completely ignore it.
– Never reply or forward the email.
