I am currently in the first week of my 3 months long vacation in Japan, and I decided to buy some stuff. I found out that I could get the items taxfree in store, and thought "that's a smart thing to do". So I got my stuff taxfree.
What I didn't know was that I couldn't use my products before I left Japan, and that's not gonna happen for a long time, so now I am just really regreting my action and wondering if I could pay back the tax?
Is there possible for me to use the products before i leave Japan? Or do i have to leave to be able to use them?
