Hello & Konnichiwa,
I am using hyperdia to plan my trip. I will have a JR Pass. Hyperdia gives me the schedule including ROKUMON train when I click on “JR railway only” at the search criteria (no private railway).
I am wondering if Rokumon is a JR train and my pass will be valid on it, or a Shinano train and I will need to buy a ticket?
Thank you for your answer in advance,
The Rokumon train is part of the Shinano Railway. It is a special tourist train that has in-car dining and other unique services. You can see more information about it on its official website (in English).
To travel between Nakakaruizawa and Karuizawa, please take the regular Shinano Railway train.
I hope that helps answer your question.
