info on how to get from A to B

hi, i'd appreciate it if someone could tell me how to get from:

1) Kanazawa to Shirakawa-go
2) Shirakawa-go to Takayama
3) Takayama to Kiso Valley
4) Kiso Valley to Kamikochi
5) Kamikochi to Matsumoto
6) Matsumoto to Tokyo

by cheaper means than the shinkansen, such as direct buses or highway buses. if you could tell me the name of the companies, that'd be awesome too. Thanks!!

The more efficient route would be: Kanazawa - Shirakawago - Takayama - Kamikochi - Matsumoto - Kiso Valley - Matsumoto
