It's a bank card for the Japan Post Office (like Switzerland, Japan's postal system also provides banking services).
My grandmother in Japan has the same card and she uses it primarily as her bank because the post office/bank is literally at the floor level of her condo.
Japan doesn't use the term "bank card." "Cash card" (キャッシュカード) is the
wasei-eigo terminology used for an ATM card; think of it as a [get your]
cash [out of the bank's ATM]
card.
If you're interested, there's an
impartial list of many Japanese wasei-eigo on Wikipedia.
