I'm sending a lot of items back to the UK from Japan and paying about triple the standard cost to register my mail (kakitome; 書留). However, I've yet to find a portal where I can actually claim on undelivered mail. I'd like to know:
- how long has to pass before I can claim, and
- whether registered means it's tracked and traced just in Japan or in the recipient's country as well.
I have looked all over the English version of the Japan Post Office website to no avail.
