As the title declared. I was wandering about using JR Pass for entering Kitasenju Station or nearby station such as Nippori Station to go straight to Ayase Station.
From what I search. It seems that JR Ayase still count as one station of the Joban line but the line between Kitasenju and Ayase seems to be a Chiyoda line. So I'm not quite sure that Can I just change the train at Kitasenju Station to Ayase station and get off like that?
Or I need to ride the Joban line and get off at Matsudo Station and ride the local Joban line to get back to Ayase Station so it will be fully covered by the JR Pass.
Thank you for answer in advance.
