FNNプライムオンライン, Zonebourse and NEWS GEISPO reported a data breach at Joshin (Japan) on 26 October 2026, and it has been confirmed. It affected 6,230,000 records. Exposed: Passwords and logins, Phone numbers, Names, Addresses, Member IDs and Subscription contract information and more.
Look for Joshin’s own notice or letter: it should say what of yours was involved. Keep it.
Change your Joshin password, and the same password anywhere else you use it. Turn on two-step sign-in.
Expect scams that use your details: calls, texts or emails pretending to be Joshin, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
