One in Three Japanese Companies in Poll Report Cyber Incidents

Tokyo, 12 November 2026 – About one in three Japanese companies responding to a survey released on 12 November said their own systems or those of an external service provider had been hit by a cyberattack this year. About 10% reported disruption to operations, while 22% reported an attack that caused no damage. The poll was conducted from 27 October to 6 November and drew responses from 214 of the 508 companies contacted.

For Asian businesses with suppliers or service providers in Japan, the findings highlight a risk that extends beyond a company’s own systems. An interruption at a provider can affect deliveries, billing or customer service even when the client’s network is unaffected. The results describe the companies that answered the survey, not the incidence of cyberattacks across all Japanese businesses. They also distinguish attacks that interrupted operations from incidents respondents said caused no damage.
