How do we know which train is covered by JR pass

Hello there,

Basically all JR trains in Hokkaido are covered by the JR Pass. [Full validity can be found here], we also have a great interactive map with all lines covered. I would also recommend learning to plan with Hyperdia, this way you can find all JR trains, in addition to a lot of other helpful information.

1.) Yes this train is covered.

2.) There is no train station at Sounkyu, so you will want to use a bus instead. This costs around 900yen from Kamikawa.

3.) Here is how to access Asahikawa Airport.

Hope this helps,
Daniel
