Hi,
I'm arriving in Tokyo on April 3rd.
If you're still there at that time, I'd like to pass by to take a look, because I'm sure you'll have something i need.
some info: The last time I left Tokyo, the big thing was cancelling cell phones & other contracts. Depending on your bank (mine was Risona), you don't need to bother cancelling that because they don't have any monthly fees; they just close the account automatically if there is no activity for like 2 years.
Good luck, and looking forward to hearing back from you!
