JR East announced a special plastic Suica card for inbound tourists called “Welcome Suica” that will be available from September 1, 2019 at major Tokyo area stations and service centers. The main attraction according to the press release is that the Welcome Suica card does away with the ¥500 deposit, and the hassle of getting it back when leaving the country, but the card is only valid for 28 days from the issue date.
You can be sure that Welcome Suica cannot be added to Apple Pay or Google Pay and will strictly be plastic issue like Rinkai Suica and Monorail Suica. JR East also says that unused Welcome Suica balances will not be refundable but the unique card design makes a nice souvenir.
The whole thing sounds like it would have been a nice idea before Apple Pay Suica and Google Pay Suica, both of which let users to add virtual Suica cards without a deposit.
