about Ltd. Exp Super Hakuto

hi,
im planing to have a trip to tottori.then i found this two limited express called
1.LTD.EXP SUPER HAKUTO
2.LTD.EXP SUPER INABA
my question is ,
1.can i ride them by using all JR rail pass all the way to tottori?
2.do they have any unreserved car like shinkansen?

can i ride them by using all JR rail pass all the way to tottori?

No, these trains partially run on non-JR railway tracks, which means that pass holders have to pay a supplement. I believe the supplement is about 1800 yen one way.

do they have any unreserved car like shinkansen?

Yes, they have reserved and unreserved cars.

I rode it a few years ago and overlooked the non JR bit. No drama, the conductor wrote me out a supplementary during the non JR ticket inspection.

thanks a lot for ur reply.
i need a little more information.i wanted to know
1.from where the non JR track starts.
2.from which station i have to get the supplementary ticket and how.

It is non JR from Kamigori to Chizu if I recall correctly. You may be able to pay the supplement when booking but I just paid the conductor on board the train.The Chizu company people come through for a ticket check in their section.
