ticket for Kurobe Tateyama alpine route

I plan to take a trip from Toyama to the Kurobe Tateyama alpine route and return to Tokyo this October. I will be staying in Murodo overnight, so there should be enough time. Can you tell me whether I can get any combination ticket that will cover the transportation throughout the whole journey?

Thank you.

For your trip, there is a need to buy each ticket to go to Toyama from Tokyo, and back to Tokyo from Shinanoomachi. If you go to Tateyama from Tokyo, a combination ticket is not sold, on the other hand, the ticket to the starting point at Osaka and Nagoya have been sold.
The ticket for Alpine route can be booked on the web.
