I am visiting Japan this October for 2 weeks and I would like to spend 2 days in Sapporo but I am confused regarding the travel time from tokyo to sapporo. I am interested on the sleeper train to save time but I can not look for any clear information about it. I have recently read about HOKKAIDO SHINKANSEN which was opened since March 2016. Link is here https://www.sapporostation.com/hokkaido-shinkansen-traveling-from-tokyo-to-sapporo/
Could anyone help me regarding this route, schedule and if sleeper train going to Sapporo is possible. Thank you! Arigatu!
By the way I will be having a 14-DAY JR PASS.
