An online bank with
a long heritage

As part of Sony Financial Group, we've been using
technology to help customers bank better since 2001.

Hello, we're Sony Bank

We're an online bank. That means you won't find any Sony Bank branches. Instead, we're at your fingertips. We're here to make banking simple for customers on the go - in and outside Japan. No long queues, no inconvenient opening hours, and no language barriers. Just better banking. Anytime, anywhere.

CEO message

    Thank you for being our loyal customers.

    Sony Bank was established in June 2001 as an online asset management bank for individuals. Ever since our launch, we have embraced a "Be fair" corporate policy, entered new frontiers and used technologies to grow our business.

    Today internet banking is so common that transaction capabilities alone cannot differentiate us from competitors. We are therefore creating unique products and services based on unique ideas and the latest technologies to stand apart and provide new value to customers.

    We are also further enhancing compliance and information security to ensure the uncompromising soundness and peace of mind required of banks.

    Our goal is to continue raising the trust and satisfaction of customers and become an internet bank they feel close to in a mutually beneficial relationship that flourishes for years to come.
