Unauthorized access to Keisei Electric Railway's Skyliner seat reservation system (up to about 3.37 million records): user IDs, encrypted passwords, names, phone numbers and email addresses may have been obtained — what users should do
On November 13, 2026, Keisei Electric Railway announced that a third party had gained unauthorized access to its Skyliner seat reservation system late at night on Wednesday, November 11, 2026. Customer information of the Skyliner Ticketless Service may have been obtained, covering up to about 3.37 million records. The items are user ID, password, name in kana, phone number and email address; the company says the passwords are encrypted, so a third party cannot recover them. Affected customers will be contacted individually at their registered email address at a later date. To strengthen security, the company has suspended the whole seat reservation system, and it has not said when it will resume. Skyliner tickets are still on sale at station counters and ticket machines. As of November 15, 2026, no follow-up notice had been found. This site's conclusion: names, phone numbers and email addresses can be used to make genuine-looking contact, so be ready for emails, texts and calls in Keisei's name. The company says the passwords are encrypted, but if you reuse the same password on other services, change it there as a precaution.
