Where’s Kanazawa bus stop ?

I plan go to Kanazawa sta. on 6.00 AM. by from Ueno. Where's Kanazawa bus stop to Shiragawago for resevasion ticket bus and map?

Are you taking the Nohi Bus? Their website says that their buses stop at the Kanazawa Ekimae bus stop and I think that's just outside the east exit of the station. When you make your reservations there should be info on which stop it is. Check out this page for a good map of the bus stops at Kanazawa Station (scroll all the way down):

Also the station has a tourist information center with english speaking staff just next to the east exit, as well as a bus info center just outside the east exit. You could always find out there as well.

Also, here's the English site for Nohi Bus in case you don't have your bus tickets yet.
