If you need to change your login name for higher education, etc.
GSIC uses the information as of the first day of each month to make a batch change around the 10th of the month.
Therefore, there is no need for you to apply for or re-register for a new TSUBAME account.
Until the change, please use your old TSUBAME login name.
Please note that the timing of the change may not coincide with the timing of the Tokyo Tech IC card, which is the source of the information, and it may take a long time for the change to be completed.
If you wish to change your login name as soon as possible for some special reason, please contact us using the contact form.
