As of February 25, 2022, to strengthen network security, the Bank of Japan will disable Transport Layer Security (TLS) versions 1.0 and 1.1 for encrypted communication on its website.* The Bank will continue to accept internet connections from networks using TLS 1.2.

Major browsers to be affected are as follows.

For PCs:

  • Firefox 23 and below
  • Chrome 29 and below
  • Safari 6 and below

For smartphones:

  • Default browser for iOS 4 and below
  • Default browser for Android 4.3 and below

Users are kindly requested to make sure that their browsers support TLS 1.2 and take appropriate steps, e.g. upgrade the browsers and/or enable TLS 1.2 on their devices.
For inquiries regarding TLS 1.2 compatibility, configurations, and web environment for your device, please contact the relevant device manufacturers or system administrators.

We appreciate your kind understanding.

TLS is a protocol that (1) provides security by encrypting digital communications between a website and a user thereof and (2) ensures that no third party can eavesdrop or tamper with any message.
