Hankyu Corporation announced in January they would sell ICOCA cards for commuter pass use starting March 1. The switchover is interesting on many levels. ICOCA is the JR West transit IC card and PiTaPa is the transit IC card for Kansai area private lines (Hankyu, Keihan, Hanshin, Kintetsu, etc.). They are both FeliCa cards, offer commuter passes and are compatible for transit use under the Japan Transit IC Mutual Use Association project specification.
There is one big difference: ICOCA is prepaid while PiTaPa is a postpaid credit card/transit card hybrid that can never really be mainstream because it has credit checks. ICOCA can be bought by anyone at a ticket machine. The Hankyu/Hanshin switchover to prepaid ICOCA for the masses follows the JR West arrangement that Kintetsu and Keihan already have in place. There is just one last little detail that JR West needs to work out however: get ICOCA on mobile digital wallet platforms like Apple Pay and Google Pay. Super Suica should take care of that in 2021.
