Who do you have your Japan card through? By last year, all of the Japan visa/mc issuers were required to provide compliance with the MC SecureCode or Verified by Visa program. (There's also one for JCB) You just need to have setup your online statement viewing and the same username/password combo is used for the verification screen, in most cases. I have two visa cards from SMBC and one MC from MUFJ.

Anyway... SE supports all three.
