Logging In

A. How To Log In

Go to the login page using your browser:
http://keio.jp/

Enter your Keio ID and password.

Form Format Example
Keio ID [user name]@keio.jp or
[user name]@[subdomain].keio.jp
keiotaro@keio.jp or
keiotaro@xx.keio.jp
Password Password specified for the ID entered in the Keio ID field Ju92#1515Yo

After correctly entering the ID and password, click [Login].

B. If Your Login Fails

If your login fails due to an incorrect Keio ID or password, an error message appears in red under the ID/password fields. Check the following:

  • Are your Keio ID and password correct?
  • Did you enter your entire email address (Keio ID), including the domain name (e.g.xxxx@keio.jp or xxxx@z1.keio.jp)?
  • All the characters of your email address (Keio ID) and password must be 1-byte characters. Did you accidentally enter any 2-byte characters?
  • The Keio ID domain name is "keio.jp or xx.keio.jp". Did you mistakenly enter "xx.keio.ac.jp" instead?
  • Is the Caps Lock or Num Lock key pressed?
    You might have pressed the Caps Lock key when you registered your password during activation.
  • Have you completed the activation process?

If your login still fails, contact the Help Desk right away.
