The ECCS email system for students changed over to the ECCS Cloud Email using Google’s G Suite for Education in April, 2016. Some of the web applications have been available from the beginning even though they have been used as an alternative email system. In May, 2017, along with the easing of the restriction for using the applications and partly from the easing of the restriction for email system, we have decided to announce how to use the applications for the G Suite for Education, which had not been announced sufficiently enough on this website.

Please note that initial setting is required when you use for the first time. Please refer to How to use ECCS Cloud Email -Initial setting, etc.- for details.
In addition, please see Information on ECCS Cloud Email for the outline, and Operation policies for the ECCS Cloud Email (currently available only in Japanese) for the ECCS Cloud Email's operation policies.

Important Things to be Considered

Multi-Factor Authentication (MFA)

You can log in to the ECCS Cloud Email with your UTokyo Account. Even though it is possible to save important data using ECCS Cloud Email as it is not possible to sufficiently protect your account solely with a password, even if you do not reuse same passwords or set up an easy-to-guess password, please set up multi-factor authentication (MFA) for UTokyo Account.

Use of Multiple Accounts

Some users may already have a Google account (, etc.) other than the ECCS Cloud Email. It is possible for many Google web applications to be used while switching between multiple accounts. However, if users tend to use many accounts and applications at the same time, it will be useful for users to use Google Chrome as the main web browser and log into each Google account on its own window.

Backing up and saving your data following graduation

Your ECCS Cloud Email account will be deleted following your graduation. Please refer to “(New) Notice for ECCS users leaving the University of Tokyo following graduation, retirement, or resignation" for details on the deletion of accounts following graduation. In order to save or copy data in one go to other Google accounts, we recommend users to create an archive following the steps given in “Backing Up Contents (Method of use)" and download them on your PC, etc.

If you have lost the device

If you have lost the device on which you use your ECCS Cloud Email account, please change the password immediately(UTokyo Account User Menu).
