Nearly 30% of Large Japanese Companies Report Data Leaks

Oct 20, 2026 | News On Japan

TOKYO - Nearly one in three large companies in Japan have experienced a data leak or a suspected breach, according to a survey released by Teikoku Databank on October 19th, highlighting growing concerns over corporate information security as unauthorized access incidents continue to affect businesses across the country.

The survey found that 16.2% of companies overall reported having experienced an information leak or an incident in which a leak was suspected. Among large companies, the proportion rose to 30.2%. The figures include incidents caused by human error as well as cyberattacks.

The findings also revealed significant gaps in companies' ability to detect security incidents. A total of 14.8% of businesses, particularly small and medium-sized enterprises, said they did not know whether any information had been leaked.

Several respondents cited a lack of specialist personnel as the reason for their uncertainty, indicating that some businesses may be unable to identify breaches even when they occur.

Teikoku Databank emphasized the importance of establishing systems capable of detecting information leaks, particularly among small and medium-sized companies that may lack dedicated cybersecurity expertise.

The research suggests that preventing unauthorized access is only part of the challenge, with businesses also needing effective monitoring and detection systems to ensure that potential information leaks do not go unnoticed.
