Hello, i've planned to go to Japan in November-December, and I would like to go to Sapporo, using only my JR Pass, and if possible, with night trains, so I went to Hyperdia to check for a route, I think I found something that is good for me, but I need to be sure it's only using trains that I can use only with the JR Pass.
Here is the travel:

Tokyo > Sendai : Shinkansen Yamabiko 221
Sendai > Hakodate : Ltd.exp Hokutosei
Hakodate > Sapporo : Ltd.exp Super Hokuto 1
Please tell me if this is good with JR Pass, and if it's not, what kind of trains should I take to go to sapporo by night without extra fee (if it's possible).
Thank you!
