We stopped updating this site on June 30, 2024. From now on, information on Educational Campus-wide Computing System (ECCS) will be provided at utelecon The Portal Site of Information Systems @ UTokyo.
Immediately after changing the initial password for the UTokyo Account, such as when you use the UTokyo Account for the first time, you may receive “Incorrect user ID or password. Type the correct user ID and password, and try again” message on the ECCS User Menu. This happens even though you have successfully signed in and the screen has moved to the ECCS User Menu (idm.ecc.u-tokyo.ac.jp).
This occurs because it takes at most ten minutes for the password change in the UTokyo Account to be reflected in the ECCS User Menu.
If the above error message appears, please wait for about ten minutes from when you changed the password.
We apologize for any inconvenience and concern that this may cause.
