The story

Sony Bank launched in 2001 as a pioneering internet-only bank in Japan under the Sony Financial Holdings umbrella. The bank differentiated itself through multi-currency foreign deposits and a globally usable Visa debit card (Sony Bank WALLET), winning consistent top rankings in Japanese net-bank customer satisfaction surveys. Over time, Sony Bank layered on mortgage lending, a card loan product (guaranteed by Acom), and open banking API connectivity. By 2025, the bank is positioning as a comprehensive digital retail bank leveraging the Sony Financial Group's insurance and investment ecosystem.
