These limited express trains, Kamui and Lilac connect Sapporo and Asahikawa. Kamui and Lilac run on exactly same route. The only difference is accommodation. Lilac has Green seat and Kamui does not. But the reserved ordinary seat of Kamui is called “U seat”. It has better seat with some equipment. But it is a sort of Reserved Ordinary seat. So JR Pass Ordinary covers this seat.
In this post, I show you the details of these train and the timetable.
