> People can obtain digital addresses by registering with Japan Post's Yu ID membership service. Their digital addresses will not change even if their physical addresses change.
OK, so your social security number is your "digital address", and the post office has a database of everyone's current address.
I'm not sure what problem this solves. Shaves seconds off the time it takes you to write an address? Better hope they've got error correction built in, since normal addresses are fairly "fault tolerant" in terms of still being deliverable.
If you move you still need to notify them, although perhaps in Japan big brother already knows you've moved.
