Toshiba Group companies will unify their email address domains to ‘@mail.toshiba,’ in a transition that will start in April this year. The move is part of a wider shift under which Toshiba will unify its online presence to the ‘.toshiba’ top-level domain^*1, accessible only to Toshiba Group and highly secure. The change will give Group brand consistency across its operations and ensure safer, more secure communications with customers and stakeholders.

The transition will start with Toshiba Corporation^*2, which largely uses ‘@toshiba.co.jp,’ and from there it will be extended to Group companies around the world. As email addresses for various inquiries will also change, we ask all parties that communicate with Toshiba and that have specified domains in email receive settings^*3 to add ‘@mail.toshiba’ to the list.

Thank you for your understanding and cooperation.

*1: Top-level domains (e.g., ‘.co.jp,’ ‘.com’) are the highest-level in the internet domain hierarchy and indicate the location or type of the organization. ‘.toshiba’ is a top-level domain that can only be used by the Toshiba Group, which will prevent unauthorized use of email addresses by phishing emails impersonating people in Toshiba Group and reduce security risks. Toshiba Group now uses generic top-level domains such as ‘.co.jp’ and ‘.com.,’ with different Group companies in different countries and regions using different email addresses.

*2: Including Toshiba Infrastructure Systems Corporation, which will be integrated into Toshiba Corporation on April 1, 2025.

*3: The email addresses assigned to individual employees of Toshiba Group companies will be changed in turn, at different times or each email address. When the domain is changed, the account name (the part before @) will also change. Emails sent to old email addresses will initially be automatically forwarded to the new email address, but after some time old addresses will no longer be recognized or usable. If you have registered an old email address in your email client, etc., please change it to the new email address when you are contacted by a Toshiba representative with details of the email change.
