However in some cases, "Partir" can also be used with the preposition "À", as in "to leave TO a place"; it's quite common especially for trips:
Partir au Canada/To leave to Canada..
In this case it's almost like a synonym of "Aller", like here:
"Je devais y partir" means "I was supposed to go there"
The use of "Y" replacing "AU Japon" (and not "EN" which would replace "DU Japon") indicates we're talking about a destination.
Here are a couple more expressions with "Partir" used to refer to a destination:
Partir en voyage = To go on a trip
Partir en vacances = To go on vacation
Hope this helps :)
