while I would hope so, this is rarely the case - its trivial to clone a usb key, even if its hardware encryption, and as this person freely copied it, it would appear policy is not in place (like denying usb devices in corporate machines). most "encryption" is either bitlocker or a numeric pin, which is very easily defeated. But also claiming no attempt has been made is impossible as they have no way of knowing if it was read, which was my point. The other obvious point is the Japanese are very deferential people, so it may be worse than admitted.
