So I moved back to the UK in early Dec 2011, but I have started getting letters from Kobe City tax office saying that I need to pay them 100,000 yen (yes, 10man) city tax for the period Jan to June 2012. I contacted them to say "but I am not living in Japan anymore" but they insist that I have to pay it anyway.
I have never heard of this before from friends moving home, and it didn't happen to me when I left JET.
Has anyone else come across this one?
