Please Help with this 15 day Itinerary - JR Pass

Hi, I'm no expert on this so someone may have a better reply, but based on my research to date the trip from Takayama to Shirakawa-go and from there to Kanazawa is by bus, both with the same company. I found this helpful link for the timetable and costs and an indication of when reservations are needed with one company. I don't know if there are other options but this is a good guide...
No idea if JPR can be used for that bus company sorry.

Have fun.

Also, still on the bus to Kanazawa issue, this helpful link that has two bus companies going...

it says the bus isn't cover by the JRP.

Thank you Marie for your help. If anyone else can help I would greatly appreciate it!!

Hi there,

Marie posted some great information on the bus from Kanazawa/Takayama to Shirakawago. You do indeed need a reservation for the bus, which can be bought at either train station. There are English speaking tourist information desks available, which are a great help! When purchasing a ticket you can buy a one way ticket Takayama - Shirakawago and a ticket later on the same day Shirakawa-go at the same time.

Okay, now to rail travel. Your research is very good, first the route from Tokyo - Takayama takes you with the Shinkansen to Nagoya and then with the Wide View Express to Takayama - route is completely covered by the JR Pass.

Kanazawa - Mount Koya, first take the Thunderbird express to Osaka. From where take a local train to Shin-Imamiya. At Shin-Imamiya change train company and use the Nankai Express to Gokurabashi (¥850), this is the station for Koya. The route looks like this.

Mount Koya - Kyoto. First take the Nankai Express back from Gokurabashi to Shin-Imamiya, here take a local train to Osaka station, from which you can use the JR Kyoto line to Kyoto. The route looks like this.

Travel to Hiroshima and back to Tokyo.
With the JR Pass you can either use the Kodama or Hikari Express to Shin-Osaka and transfer there to Sakura Express bound for Hiroshima. All these trains are included, Himeji is directly on the route to Hiroshima and all trains make a stop there. For travel back to Tokyo, use the Sakura to Shin-Osaka and the Hikari from there to Tokyo station.

I hope this helps!

Thank you so much, Daniel!

I have a question on the following two routes. Which (if any) of these trains are covered by the JR Pass? Thank you.

Kanazawa - Mount Koya, first take the Thunderbird express to Osaka. From where take a local train to Shin-Imamiya. At Shin-Imamiya change train company and use the Nankai Express to Gokurabashi (¥850), this is the station for Koya. The route looks like this.

Mount Koya - Kyoto. First take the Nankai Express back from Gokurabashi to Shin-Imamiya, here take a local train to Osaka station, from which you can use the JR Kyoto line to Kyoto. The route looks like this.

The JR Pass covers the part Kanazawa - Osaka for the first route and Travel from Shin-Imamiya - Kyoto on the 2nd.

In other words the Nankai Express is the only part not covered.

Hope this helps :)
Daniel

Thank you again Daniel for all your help!!
