I am not sure if this is the right place to ask this question but I wasn't sure which stackexchange site I should post this too.
I currently live in the UK and send monthly packages to my friend who lives in Tokyo, Japan. Due to a recent personal problem, I am no longer able to send packages directly to her house. Therefore she told me to send it to a post office instead and she would collect it from there. After some extensive googling, I found that this kind of service is called "kyoku dome" (局留め) but there doesn't seem to be a guide for my situation. Also this only seems to be able to be done inside of Japan but I am unsure. I have asked my Japanese friends but they either don't know or haven't sent packages to a post office in Japan from outside of Japan.
Is it possible for me to send a package, addressed to a post office in Japan with her name on it, from the UK and somehow get my friend to collect it? Does anyone know the procedure?
