JSR Corporation (Head Office: Minato-ku, Tokyo; Representative Director, CEO and President: Tetsuro Hori) will unify the email domains used across the JSR Group starting Wednesday, July 1, 2026.

By unifying the multiple email domains currently in use within the Group into a common domain, we aim to present a clearer brand as a unified corporate group and further strengthen the Group’s overall capabilities.

■Overview of the changes

- New domain: @jsrgr.com

- Start date: Wednesday, July 1, 2026

* The start date may vary for Group companies in some regions.

* In consideration of business structure, some Group companies will not be included in this integration.

■Information for customers and business partners

- Emails sent to existing addresses using the former domains will continue to be delivered to the relevant employees.

- Depending on the security settings of your email systems (such as anti-spam filters or domain blocking functions), emails from the new domain may not be received correctly. In such cases, our representatives may contact your company separately to provide guidance or request adjustments to your settings. We appreciate your understanding and cooperation.
