Microsoft’s current support article specifically warns that the normal Skype Credit reactivation process works differently in Japan.
More importantly, the Microsoft Services Agreement stated the Japan exception explicitly: when a user located in Japan purchased Skype Credit from the Skype website, the normal inactivity/reactivation rule did not apply. Instead, the credit expired 180 days after purchase, and once expired it could no longer be reactivated or used.
