J-WESTQuick! is an official JR-WEST app that lets you quickly access the login screen of JR-WEST’s e5489 service and JR-WEST’s My Dia timetable and fare search service.
By signing up for a J-WEST ID, when you access the e5489 login screen via J-WESTQuick!, the app will automatically remember your J-WEST ID. This eliminates the need to enter your J-WEST ID every time you log in, making the reservations procedure more convenient than ever.
*It is possible to use the app even if you have not signed up for a J-WEST ID.
However, you will need to sign up for a J-WEST ID beforehand to use the app to access the login screen of the e5489 service.
