We will be in Osaka for 3 days without the need of a JR Pass since we will be spending the first two days using a hop-on hop-off and enjoying the Tenjin Festival, then on the third day will be going to the Osaka Universal Studios.
The next day we wish to go to Sapporo and for the below reasons were thinking of catching the sleeping train from Osaka to Tokyo
1. to deposit our luggage in Tokyo without taking them on the low-cost flight from Tokyo to Sapporo
2. to experience an overnight sleeper train
3. Flights from Tokyo to Sapporo are cheaper and shorter
My questions are how can I see the prices including bedding for the Sunrise train? When we arrive in Sapporo New Chitose, we will be going to Usuzan and the following day to Asahikawa,
so should I consider some kind of pass to cover the sleeper train, the trip from Tokyo to Haneda Airoport and the travel until we arrive in Asakihawa? Then, the plan is to rent a car.
