All University Mail FAQ
If you cannot log in from http://mail.st.kyoto-u.ac.jp/, you are asked to confirm whether you can log in to https://ecs.iimc.kyoto-u.ac.jp/. If you cannot log in to both, your password seems to be wrong. If you want to reset your password, please consult at the support desk in ACCMS South Building with your student ID card or faculty ID card.
If you change your ECS-ID password, you cannot log in for an hour because it takes up to an hour to reflect password changes in our system. If you cannot log in, wait for a while and retry later.
