Busses to Himeji Castle

Which bus goes to Himeji Castle from Sanyohimeji Station?
If we purchase Kansai Thru pass, is the bus cover under this pass ?

Buses are not covered in Himeji as shown by the following map:

(note that Himeji is outside the orange zone, which indicates the area in which buses are covered)

But it is only a pleasant (if the weather is fine) 15 minute walk from the station to the castle.

The castle is visible from Sanyohimeji station (private railway) and Himeji station(JR).

The castle is under renovation right now until 2014. It is completely covered by scaffoldings. Probably not worth your time.
